What's New in Version 5.6.5
The new features and miscellaneous enhancements outlined below were
introduced in the 5.6 Version.
Product Enhancements for
Release Date: June 4, 2002
- More on Session-Specific Trading
The introduction of session-specific holidays (see item #29 above) necessitated simple but widespread revisions to Investor/RT date/time manipulation functions. A bug slipped by our testing of this new facility and it has been corrected in Version 5.6 Rev 5. The error affected charting of instruments assigned to sessions other than session 0, where session 0 was defined as having a recent session-specific holiday in the holidays.txt file.
- Editing Closed Portfolio
The Investor/RT portfolio management feature enables editing of most open position data items in the portfolio window itself by simply editing the cells in the portfolio spreadsheet. However, once a position is closed, the position information is not long present in the portfolio window. The Portfolio Reports tool on the portfolio toolbar can be used to view summary or detailed reports of closed positions, but this information could not be edited in any way to correct data entry mistakes, etc. Version 5.6 Rev 5 introduces a closed position editing facility for this purpose. To access the new feature first click on the “Portfolio Reports” button on the toolbar. When the portfolio window appears, choose the time period of interest (this year, this quarter, this month, this week, etc.) and click the new “Edit Closed Positions” button. An editing window will appear listing all of the closed positions by closing date. The list can be displayed sorted by ticker or closing date as desired. As you select any position in this list, its information appears in edit boxes to the right. The following items can be adjusted:
- Position Type (Long or Short)
- Open Date/Time and Close Date/Time
- Open Quantity and Closed Quantity
- Open Price and Close Price (per share or per contract)
- Commission Amount
- Text Description (up to 32 characters)
After making changes press the Apply button to save the changes; you can then continue editing other closed positions. Click OK to save the changes and dismiss the window. A button is provided for deleting the selected closed position so it will no longer appear on the summary or detailed closed position reports. The delete function will be supported in a future release.
- Chart Panning Delay
Setup: Preferences: Charts: General now has a checkbox and entry box for specifying whether you want to delay activating the chart panning tool when you mouse down inside a traditional chart window. If the checkbox is not checked any mouse down in a chart window that does not “select” some element will activate the chart panning tool instantly so you can drag the chart immediately in any direction. If the checkbox is checked then the software will delay the specified number of seconds (e.g. 1.25 seconds) before activating the panning tool. The default for new users of I/RT will be to delay 1.25 seconds. This setting avoids accidental panning of the chart when you click in the chart. This can happen for example, when you click to select an indicator and “miss”. Such accidental panning will put the chart into manual scaling mode. It is recommended that you specify at least a small delay, even .5 seconds, so that “missed” clicks do not have this unintended side-effect.
- Session-Specific Trading
Trading holidays can now be made specific to a particular trading session rather than global for all sessions. This new feature will be of interest to users of Investor/RT who monitor both U.S. and international exchanges. When the U.S. has a trading holiday, the markets in Europe are often open for trading and vice versa. Thus, this feature enables the user to specify holidays that are specific only to the instruments that are assigned to a particular trading session (or sessions) but no others.
At present, the specification of holidays is accomplished by editing a text file named “Holidays.txt” located in the admin folder/directory inside the Investor/RT folder/directory. The file was formerly named “Holidays” with no file name extension. The .txt extension was added in this release to make it easier for Windows users to edit this file with Notepad by double-clicking on it. Alternatively, you can open the file using the File: Open command in Investor/RT, make changes to the file and use File: Save to save it.
Each line in the file specifies a date, the name of the holiday, and a code indicating whether the holiday is global (code H), or whether the holiday is specific to a particular session number. Here are some sample lines in the Holidays.txt file:
-Year 2002 Trading Holidays
Lines that begin with a hyphen are comments, other lines have the format:
Be careful. The two digit year number must come first, then the month, then the day. Dates are always six numeric digits followed immediately by a comma. The code can be the letter H (it must be capital H) to designate a global (all sessions) holiday. The example above is from our default holidays.txt file. It is setup for U.S. Trading Holidays for all sessions. An Investor/RT user in Europe who tracks U.S. stocks in session 0 and European exchanges using other session(s), can edit the holiday.txt file as follows:
-Year 2002 Trading Holidays
020527,0,US Memorial Day
020704,0,US Independence Day
020902,0,US Labor Day
021128,0,US Thanksgiving Day
These adjustments limit the holidays (except Christmas) to session 0 instruments. All other trading sessions are considered open on those days.
The dates in the holidays.txt file must be in ascending date sequence. You may include the same date two or more times if you wish to declare that same date a holiday for two or more sessions, e.g.:
-Year 2002 Trading Holidays
020527,0,US Memorial Day
020527,1,US Memorial Day
020704,0,US Independence Day
020704,1,US Independence Day
020902,0,US Labor Day
020902,1,US Labor Day
021128,0,US Thanksgiving Day
021128,1,US Thanksgiving Day
In this example of U.S. holidays May 27, July 4, Sep 2, and 11/28, Investor/RT considers sessions 0 and 1 to have a trading holiday while all other sessions are considered open on those dates. Note that it is important to leave past holidays in the file since Investor/RT uses this information to eliminate those days from traditional charts.
On the actual date of a holiday, the System Status window will show the text “HOLIDAY” as the status of each affected session.
- New Indicator: Mixed Periodicity Data (RTL:
- myTrack Trading Holiday Improvements
Further work was done on the myTrack version of Investor/RT to improve the handling of post holiday historical data downloading. Historical intra-day data from myTrack does not include the actual date for the data, only the time of each intra-day bar. Investor/RT now does a better job of inferring the date of each collection of intra-day bars by considering trading holidays. Further, we have eliminated all error message dialogs for myTrack error messages. Instead, any error messages are briefly shown in the status message area of the main toolbar. They are also recorded in the “Message Log” for future reference (File: Open: Message Log).
- Tick and Tickbar Charting and “Seconds Per
The periodicity setup window has been revised so that when Tick or Tickbar (N Ticks per Bar) periodicity is selected, the user can specify a screen resolution factor called “Seconds/Bar”. Since Investor/RT uses a fixed time horizontal axis and since ticks and tickbars are spaced out according to the time the ticks occurred or the tickbar was completed, the seconds/bar setting adjustment can improve the spacing of ticks and tickbars in traditional chart windows.
For example, a 60 tickbar chart of Computer Associates (NYSE: CA) on May 30, 2002 shows a new tickbar forming every six minutes or so. A 60 tick bar of Intel or Microsoft would form much more rapidly. So in the CA tickbar chart, setting the seconds per bar to 360 caused the 60 tickbar chart to display with closely spaced tickbars. A similar chart of Intel displays nicely at 30 seconds per bar.
The ticks per bar and seconds per bar settings can be dynamically adjusted using the keyboard. First click on the tickbar instrument graph (line, bar, candle) to select it. Then hold down the shift key while using the up/down arrow keys to adjust the seconds/bar. The shift-up arrow increases the seconds/bar thus bringing the tickbars closer together. Shift-down arrow does the opposite. Press and hold the arrow key down for continuous adjustment.
Similarly, hold down the ctrl key while using the arrows keys to increase or decrease the ticks per bar setting. As you make these keyboard adjustments, the chart window title updates to show the current values for ticks/bar and seconds/bar.
If neither the shift nor the ctrl-key is held down, the keyboard arrow keys adjust the pixels per bar setting. Macintosh users use the option key for ctrl.
- File: Export is a
The File: Export menu has been expanded into a sub-menu with five choices for what to export. Formerly, this command was used only for exporting historical data. File: Export: Historical Data is one of the choices and still has the same keyboard shortcut (Ctrl-E under MS Windows, and Command-E under Macintosh OS).
Other menu choices are provided for exporting chart definitions, scan/signal definitions, and custom indicator definitions and trading system definitions. File: Export: Chart operates on the current (front) traditional chart window, exporting the definition of that chart to a text file. See item #22 above for more information about this new feature. Similarly, File: Export: Scan/Signal and File: Export: Custom Indicator and File: Export Trading System all require that the Scan, Signal, Custom Indicator, or Trading System setup window be the front window. Note that these File: Export commands are the equivalent of File: Save as Text. Either one saves a text file that contains the appropriate object definition text. The resulting text file can be opened using File: Open, to import the definition into another Investor/RT system. This feature was added to make it clear that these objects are “exportable”. Trading Systems are exportable but not importable at present.
- Chaikin Money Flow, Smoothing
The result of the Chaikin Money Flow calculation can be optional smoothed by specifying a smoothing period and moving average type in the setup. In charts either the CMF period or the smoothing period can be dynamically adjusted using the keyboard. Select the indicator by clicking on it, then hold down the shift key while using the up/down arrow keys to adjust the CMF period. Cntl key down and use the arrow keys to adjust the smoothing period.
- Portfolio Refresh
The portfolio window has a refresh option similar to the quote page refresh option introduced recently. Portfolios can update dynamically (tick by tick) or you can specify a frequency in seconds for the portfolio to recalculate to reflect current pricing. Using the refresh option for portfolios and quote pages can considerably reduce the amount of processing needed to keep these windows updated in real-time.
- Chaikin Money Flow
A new indicator has been added to Investor/RT, called Chaikin Money Flow (CMF). For more information click here.
- Chart Export and Import
Traditional Chart window setups can now be saved (exported) to a text file. The resulting text file contains sufficient information to re-create the chart setup, including window and pane sizes, instrument preferences, indicator preferences, etc. To save (export) a chart window as a text file, right-click in the chart window and choose Save: Chart Export File from the pop-up menu. Investor/RT will prompt you for a file name and location to place the file and a comment. The resulting text file can be emailed or published on a web site to enable other Investor/RT users to import the chart definition into their own Investor/RT systems. To import a chart export file, use the Open command in the File Menu, (File: Open: File) and select the text file. Investor/RT will inspect the file and determine if it is a chart definition file and if so, the chart will be created. You can then make any adjustments you wish to the chart and Save the chart to permanently add it to your system.
During the import process Investor/RT will ask if you wish to be prompted for indicator setups. If you reply “No”, then the chart will be setup using the same preferences as the exporter of the file. If you reply “Prompt” then the setup dialog for each indicator in the chart definition will appear so you can choose your own preferences.
When a chart is imported, the chart is first opened for viewing WITHOUT any of the “preset” indicators, e.g. buttons and other instrument specific indicators. This is done so that you can see the chart setup exactly as the exporter uses it. The chart WILL contain the preset indicators used by the exporter of the file. You can choose to leave these in the chart if you wish or delete them. If you save the chart (File: Save), close and then reopen the chart, you will see the chart along with all of your preset indicators. Note that all indicator that initially appear when you import (open) a chart definition file will be saved with the chart with scope “This Chart, Any Instrument”. If you wish any of the indicators to have a different scope than that on your system you must adjust the scope preference for each indicator before saving the chart.
This new facility has a number of important uses. Investor/RT users can share chart setups with one another easily. Investor/RT users who have a charting question or problem to report can email the chart setup to support. Linn Software intends to include sample chart setups for downloading from the www.linnosoft.com web site. At some point we may add a “charts” folders to the Investor/RT installation and distribute a variety of chart export files in this folder.
- New Price Type/Quote Page Column:
A new price type, (High + Low + Close + Close)/4 is available for use in technical indicators that accept a price type specification. This price average disregards the open price and weights the average more heavily on the closing price by counting it twice. The new price type can also be used a built-in column in quote pages.
- New Signal Statistic type: Price Before/After Last
This statistic works identically to "Price At Last Signal" except a period is provided to allow access to the price of bars before or after the signaled bar. A period of 0 will cause this result to be identical to "Price At Last Bar". A period of 10, for instance, will cause the result to be the price of the 10th bar preceding the signaled bar. A negative value may be specified to access bars following the signaled bar. For instance, a period of -5 with a price of "High" would result in the high of the 5th bar following the signaled bar. The result will only change bars that signal TRUE, and then hold that value until the next signal.
- Chart Pane Element Ordering
Recently Investor/RT has gained new flexibility for adjusting the order of elements in traditional chart window panes. Right-click on a pane title to access the element ordering window to make adjustments. In 5.6 Rev 3 the order of the elements is also retained permanently when you save the chart window. When you reopen the chart later, the pane order will be exactly the same as it was when the chart was last saved. Prior to 5.6 Rev 3, the order was not restored exactly in all cases. Pane ordering affects the appearance of chart windows since the values or elements at the top of the list are seen first (from left to right) in the pane title and the elements at the top are drawn last graphically, causing them to appear more “above” in the chart.
- Quote.com Sector/Industry Option
Quote.com supplies textual values for both Industry group and Sector for equities. Some users have indicated that they prefer to use their own classification scheme for their stocks and have elected to do so by importing these data items for each stock from another source. If you do this, there is now a checkbox in the Quote.com data feed preferences window that will turn off the automatic updating of these items from the data feed so that the imported values will not be disturbed.
- Alternate Calculation Option for True Range
A new checkbox has been added to the True Range Indicator labeled “Actual Range of Last X Bars (MaxHI – MinLO)”. When this checkbox is checked, the result will be the actual trading range over the bars specified. For instance, if a period 10 is specified, then the result will be the highest high over the last 10 bars minus the lowest low over the last 10 bars. If a smoothing period greater than 1 is specified, then the resulting actual range values will be smoothed accordingly.
- New Indicator: Signal
he Signal Statistics indicator (SSTAT) allows for statistical calculations on signals, including summation, consecutive signals, frequency, bars since last signal, change since last signal, and more. SSTAT allows the user to select any existing scan or signal, and a statistical result to calculate on that scan/signal. For more information, click
An Investor/RT "plug-in" is a computer program for calculating a technical indicator or trading signal. Plug-in indicators are not built into Investor/RT directly, they are developed (programmed) externally by Investor/RT users having the requisite computer programming skills, or they may be developed by third party software vendors who wish to market proprietary technical indicators and/or trading signals to Investor/RT users. To develop plug-in indicators, you use the Investor/RT Software Developer Kit (SDK) discussed in item #17 below. For more information on using plug-in indicators, click here.
- Investor/RT Software Developer Kit (SDK)
The Investor/RT SDK consists of developer documentation, header files, and sample C/C++ code illustrating how to build “plug-ins” for Investor/RT. See item #16 above for a description of how Investor/RT users setup and utilize plug-in indicators. The SDK is inherently “cross-platform”, supporting both Windows and Macintosh software development. In most cases, any C/C++ plug-in programmed as a Windows Dynamic Link Library (DLL) can be made available as a Macintosh compatible “Shared Library” (shlb type file) with only minor source code modifications. Interested parties must execute a non-disclosure agreement (NDA). The SDK is available at no additional charge to all licensed users of Investor/RT. Linn Software will provide developer support by email and
telephone consultation on a fee basis to SDK users.
- Oscillator Added to Center Of Gravity
An oscillator option has been added to the Center of Gravity indicator. This oscillator represents the difference between the COG and the Signal line (or COG.1) multiplied by 100. When the oscillator crosses the zero line in the upward direction, it represents the COG turning upward, and should therefore be considered a bullish signal. When the oscillator crosses the zero line in the downward direction, it represents the COG turning downward, and should therefore be considered a bearish signal. The reason the oscillator value is multiplied by 100 is for scaling purposes. The oscillator is really nothing more than the change in the COG multiplied by 100.
- New Options Added To Parabolic SAR
Two new parameters have been added to the Parabolic SAR indicator to give the user more control. The ""Initial/Incremental Step" parameter has been separated into two separate settings. Also, a "crossover increment" setting has been added. When this value is greater than 0, the price must cross over the SAR line by that incremental amount before causing a reversal. This can help eliminate whipsaws. By default, after upgrading, the Initial and Incremental Step parameters should both be set to the previous "Initial/Incremental Step" value. Also, the new "crossover increment" will be initialized to 0. With these settings, the SAR will calculate exactly as it did before. You should see no changes to your existing SAR unless you change the settings.
- Chart Button Titles and
Any chart button that is not a menu can now have a user-specified background color. To adjust the button color, right-click on the button to access the setup, check the “Custom Color” checkbox and pick the background color you want. The button title color is black so lighter background colors work best. Menu buttons for tickers and periodicities have a standard icon appearance and cannot have a custom color background. Non-menu buttons have a default title based on what they do. You can use a custom title if you wish by checking the “Custom Title” checkbox and entering your own title text. Note that a single space or two as the button title results in a button with a blank title. The number of spaces controls the width of the button in this case. Thus you can have very small color coded buttons that do various things in the chart. Pointing the mouse pointer at a blank button will popup a tip window telling you what the button does.
Investor/RT has long had a feature for creating a “group ticker” that refers to a quote page, e.g. an industry group quote page. To setup a group ticker, create a “Cash” type ticker symbol using Setup: Instruments. The ticker symbol must begin with ## followed by any letters you like. Tickers in I/RT can be up to 23 characters long. The NAME associated with the ## ticker should be the name of the quote page you wish the ## ticker to refer to. For example, create ##FOCUS with a name of “Focus Stocks”, where “Focus Stocks” is the name of a quote page. If you then insert the instrument ##FOCUS as a row in some other quote page, the ##FOCUS ticker becomes a “link” to the “Focus Stocks” quote page. Double-clicking on a ## ticker in any quote page causes Investor/RT to open the associated quote page for that ## ticker. Again, the association is made using the “Name” of the ## ticker, the “Name” of the ## ticker must exactly match the name of some quote page. You can use this feature to construct ## tickers for both user quote pages and/or built-in System quote page.
In Version 5.6 we have further enhanced the ## ticker feature to facilitate setting up of custom instruments representing a “sum” of all the tickers in a quote page. In Setup: Custom Instruments, when defining a “Sum”, if you include a ##ticker as a component of the sum, ALL of the tickers in the quote page associated with that ## ticker will be added to the sum automatically. You can use a constant number as the “multiplier” for each ticker or you can enter V#n (where n is the user variable number) as the multiplier. If you name a V# variable as the source of the “multiplier”, Investor/RT will use the V#n value of each instrument at that time to “weight” each of the tickers added to the “sum”. This means that you must pre-specify the V#n values, either by calculating them using a scan, or perhaps by entering the weighting factors manually using a quote page for data entry.
Version 5.6 also support easy “merging” of quote pages using ## tickers. Suppose you have two ## tickers, ##LISTA and ##LISTB that refer to two quote pages, “Quote Page A” and “Quote Page B”. If you wish to create a new quote page that contains all of the tickers from either list, you can do the following:
1. File: New: Quote Page to make an empty quote page.
2. Click the “Add Instruments to QP” button to open the “Add to Quote Page” window listing all available tickers.
3. Add ##LISTA and ##LISTB to the new quote page by double-clicking on ##LISTA and ##LISTB in the “Add to Quote Page” list.
Notice that the “Add to Quote Page” window has been enhanced so that adding a ##ticker causes ALL of the tickers in the associated quote page to be added to the destination quote page. Thus by creating ## cash ticker for each of your quote pages you can:
1. Link from one quote page to another by double-clicking on a ## ticker.
2. Easily setup custom instruments to create indexes for your quote pages.
3. Easily add the ticker list from any quote page to another using the “Add to Quote Page”
- Volume Weighted Moving
A new smoothing type has been added to the growing list available in Investor/RT. The Volume Weighted Moving Average weights the price of each bar with the volume of that bar. In this way, bars with higher volume will be more heavily weighted in the computation of the average. For example, a 5-period VWMA first sum the product of the volume and the price for each of the last 5 bars. This product is then divided by the sum of the volumes to give the resulting average. Many indicators in Investor/RT allow the user to specify the smoothing type. The “Volume Weighted” option can now be found at the bottom of the list of smoothing types. The VWMA can also be accessed in the scan language by simply using the token “MA” and choosing for the smoothing type of the MA to be “Volume Weighted”.
- New Indicator: Trend Intensity Index (RTL:
A new indicator has been added to Investor/RT, called Trend Intensity Index (TII). TII is based on an article by M. H. Pee that will be available in the June 2002 issue of Stocks and Commodities Magazine. TII is used to indicate the strength of the current trend in the market. The stronger the current trend, the more likely the market will continue moving in the current direction. It is recommended to enter the market during a strong trend and ride it until TII shows signs of a reversal, at which time you should abandon your position and prepare to enter in the opposite direction.
Pee recommends using a major period of 60 and a minor period of 30. Assuming these setting, TII is calculated as follows. The 60 bar simple moving average (MA) is computed. The deviation between the closing price and this computed average for each of the last 30 bars is computed (CL - MA). Positive deviations (CL > MA) are summed to give SDPOS. Negative deviations (CL < MA) are summed to give SDNEG. Then, the 30 period TII is calculates as 100 * SDPLUS / (SDPLUS - SDMINUS).
- TTI ranges from a lower limit of 0 to an upper limit of 100
- A TII value above 50 signals an uptrend.
- A TII value of 80 means that 80% of the total deviations are up.
- When TII fall below 50, a downtrend is likely in place.
- 50 represents a level that is trend-neutral.
- The closer TII is to 100, the stronger the current uptrend.
- The closer TII is to 0, the stronger the current downtrend.
It is recommended to enter a long trade on the open of the following bar when TII is above 80. The following scan would detect this condition:
TII > 80 AND TII.1 <= 80
It is recommended to enter a short trade on the open of the following bar when the TII falls below 20. The following scan would detect this condition.
TII < 20 AND TII.1 >= 20
It is also recommended by Pee to remain in the position until a signal in the opposite direction occurs.
More information on TII will be available soon on our web site tour.
The Trend Intensity Index can be accessed in the RTL language using the token
- New Indicator: Center of Gravity (RTL:
A new indicator has been added to Investor/RT, called Center of Gravity (COG). COG is an oscillator based on an article by John F. Ehlers on page 20 of the May 2002 issue of Stocks and Commodities Magazine. COG has essentially zero lag and enables clear identification of turning points. This indicator is a result of Ehler's research into adaptive filters.
The Investor/RT implementation of COG includes an option to "Volume Weight" the oscillator. When this option is checked, volume will be used in addition to price to weight the indicator. More information on COG will be available soon on our
web site tour or you can refer to the S&C article for additional computational and interpretational information.
The Center Of Gravity indicator can be accessed in the RTL language using the token COG.
- Cumulative Volume
The Volume Analysis technical indicator has been enhanced with an "Accumulate Intraday Volume" checkbox option. When this checkbox is checked, volume will be accumulated throughout the day on intraday charts. For instance, on a 5-minute chart, the Volume Analysis study would generally display the volume of each 5-minute bar. With the "Accumulate" checkbox checked, the study will instead display the total volume for the day (session) as of that bar (including the volume of that 5-minute bar). So the first bar of the session will simply display the volume of that first 5-minute bar. The 5th 5-minute bar of the session will display the total volume of the first 25 minutes. The last bar of the session will display the total volume of the day. The effect you'll see on a chart will be a study which continually builds throughout the day towards the total daily volume, and then resets back to zero for the next session.
- Volume Weighted MACD Option
When the Volume Weighted option is checked the moving average type used in the MACD calculation is volume weighted. See Item #3 above for further details.
- Using Investor/RT
With eSignal Delayed and End-Of-Day Services
Investor/RT Version 5.6 contains a fix that enables Investor/RT to retrieve historical data of any periodicity using an eSignal end-of-day or eSignal delayed-data account. Prior to version 5.6 such downloading was only permitted for real-time eSignal accounts.
The classic Lane Stochastics calculation method dictates that the RawK represent the position of current price in relation to a recent range. This position is measured as the percentage of the distance from the low to the high. If the low of the period was 50 and the high was 70, then a current price of 65 would represent RawK of 75% while a current price of 55 would represent a RawK of 25%. From a retracement perspective, Stochastics always assumes that the high occurred first, the trend was a downtrend, and retracement is now occurring back towards the high. The RawK of the Stochastics indicator is not smart enough to know which came first, the high or the low. The “Retracement Based” checkbox in the Stochastics preferences gives the RawK value this knowledge, and therefore results in a value that represents the true retracement percentage based on the RawK period specified. This option is very similar to the “auto-retracement” option of the Fibonacci Retracement study, except it gives the ability to view the values historically, and to reference them historically in the RTL language.
- Custom Instrument Calculation
Item #2 above describes some enhancements designed to make it easy to setup a custom instrument having all of the tickers in a quote page as components. A custom instrument that is setup as the sum of say 40 other instruments has the potential to use a great deal of processing time to recalculate the value of the custom instrument every time any one of the 40 underlying instruments trades. In version 5.6, custom instruments of type “sum” that have more than two components, are limited to a recalculation frequency of 3 seconds or 20 times per minute. This change will make it possible to monitor even the most demanding index calculations. We plan further enhancements to make the recalculation frequency a user-specified setting similar to the way technical indicators recalculation options are specified.
- Multiple Periodicity Charts -
The Multiple Periodicity capability of traditional charts has been expanded to include combining Daily, Weekly, and Monthly periodicities. Now, weekly and monthly bars can been overlaid on daily charts, and then indicators can be associated to any of the 3 periodicities. More information on Multi-Periodicity Charting can be found at http://www.linnsoft.com/tour/multiPerCharts.htm.
