Three columns are available for showing the last three trade prices and three columns showing the last three trade sizes (tick volume). The column names are Last.1, Last.2, Last.3, Tick Volume.1, Tick Volume.2, and Tick Volume.3. When displayed along with the “Last” and “Tick Volume” data columns, a quote page can now show you the current and previous three trades and sizes.
• Custom Instrument Spread Calculation
  Custom Instruments defined as spreads (the difference) between two component instruments, will not begin ticking at the session open until both components have opened. This calculation change eliminates spurious ticks of the custom instrument at the open when one of the components has not yet begun trading.
• Short Interest, RTL Token SINT Added
  Short Interest is available for display in quote pages and can be referenced in RTL using the token SINT. This data value is quoted by myTrack and Quote.com data feeds.
• Fixed Export Technical Indicator Function
  The Export Indicator feature now works properly in the Windows version of Investor/RT. See item #20 above for details.
• Startup Investor/RT Window Placement Improved
  In the Windows version of Investor/RT, when you quit, Investor/RT now remembers the normal restored position of the overall Investor/RT window (called the task window) as well as the “maximized” status of the window. Upon restart, the task window is restored to the maximized state if appropriate. In addition, the task window now has a proper “restored” position, so you can restore the window to its normal position by clicking the restore button in the upper right corner of the task window. If the task window was not maximized when you quit, then it will be restored to normal status at the precise window coordinates it had when you last quit.
  
  This enhancement will be most appreciated by those who run Windows with multiple monitors and/or those that use the “maximize” and “restore” buttons often to adjust the Investor/RT task window size. In prior versions of Investor/RT, if you quit with the task window maximized, at the next startup the task window’s normal “restored” size was not available. In fact, the restored size was formerly set the same as the maximized size, thus the restore button had no effect. This new technique also fixes a bug that caused a non-maximized Investor/RT task window to be created slightly smaller at startup than it was when you last quit.
  
  Finally, if you quit while the Investor/RT task window is minimized, at the next startup Investor/RT will open in its normal restored (non-maximized) coordinates. To quit Investor/RT while it is minimized on the task bar, right-click on the Investor/RT icon on the task bar and choose “Close”.
• "Last N Bars" in Scan Markers/Custom Indicators
  Investor/RT 5.5 now honors the “Evaluate the Last N Bars” options in the Scan/Signal Marker indicator. The bar account can be set to All or some fewer number of bars to reduce processing requirements for the calculation. Similar “Last N Bars” options have also been added to the Custom Indicator and Paint Bars technical indicators.
• TSI and MACD "X 100" Options Added
  The True Strength Index and MACD technical indicator setups now have a “Multiply by 100” checkbox. The values of the indicator are simply multipled by 100 for scaling purposes if this box is checked.
• Horizontal Reference "Hide Price" Option Added
  Displaying the actual price value of a horizontal reference line is now optional. Checking the Hide Price checkbox causes the line to be drawn without any numeric annotation.
• Linear Regression "Use High/Low" Option For Raff Channels
  The Linear Regression indicator now has a new option titled “Use Hi/Lo”. This option is only visible when the “Raff Channels” option is checked. Without this option, the Raff Channels will be computed using only the closing prices of the bars. With this option checked, the high and low extremes will be considered. The Raff Channels multiple is computed by finding the maximum distance from the regression line to the price (either close, or hi/lo).
• CCI "Modified CCI" Option Added
  After making adjustments to the CCI study in our last release, we’ve had several clients request that they’d still like to access the previous computation method. We’ve made this available again with through a checkbox labeled “Modified CCI” in the CCI indicator preferences.
• Donchian Channels "Consider Closing Prices Only" Option
  Donchian Channels traditionally consider the extreme highs and lows. We’ve added an option titled “Consider Closing Prices Only”. This option causes the channels to be constructed based on highest and lowest closing prices over the period. High and low prices of each bar are not considered. For example, 15-period Donchian Channels with the “Consider Closing Prices Only” option turned on, would provide channels representing the highest close of last 15 bars, and lowest close of last 15 bars.
• Zig Zag “Use High/Low” Option Added
  A new option titled “Use High/Low” has been added to the Zig Zag indicator. This option causes the trendlines to be computed based on extreme highs and lows, as opposed to closing prices only.
• Ordering Chart Elements in a Pane
  Traditional chart window pane titles show the values of the instrument(s) and indicator(s) for each bar as you move the mouse within the chart window. The pane title is often insufficiently wide to show every instrument and indicator value. The order of the chart elements within the pane governs the order in which the values are displayed. The only mechanism heretofore to adjust the element order within the pane was a shift-click in the vertical scale area to “cycles” the elements in the pane, moving the first element shown in the pane title to the end.
  
  In Version 5.5, a more flexible method of ordering pane titles has been added. The “Order Chart Pane Elements” window can be accessed in three ways:
  
  1. Using the chart window popup menu, choose Add/Delete/Edit: Element Order.
  2. Shift-click in the vertical scale area of the pane.
  3. Right-click on the title bar of the pane you wish to order.
  
  A window appears listing the elements within the pane in the order that values are displayed in the pane title. To move an element, select it and click the Top, Bottom, Up, or Down buttons. Double-clicking on an element both selects it and moves it to the top of the list. Shift-clicking does the same. Ctrl-clicking an element (option-click on Macintosh) selects the elements and moves it to the bottom of the list. A “Cycle” button is also provided. It does what “shift-click” in the scale area used to do, that is, it moves the top element to the bottom, make the second item the new top element. The ordering window is displayed just below the pane title bar so you can click “Apply” at anytime to see how the revised pane title bar will look without having to move the window out of the way.
• Custom Indicator Lookback Period Added
  A new option has been added to the Custom Indicator preferences titled “Calculate Last X Bars”. This option allows the use to dictate how far back the custom indicator is drawn. For instance, “Calculate Last 15 Bars” will cause the custom indicator to be drawn on only the last 15 periods. This new option can help eliminate clutter on charts by limiting the drawing to as few as the last 2 bars. This lookback period can be adjusted directly from the keyboard. Simply select the indicator, and hit the right or left arrow keys on the keyboard to adjust the period down or up by 1. Scan/Signal Markers, Color Markers, and PaintBars indicators all have similar lookback periods associated with them. The lookback periods for Color Markers and PaintBars can be adjusted from the keyboard just like the Custom Indicator period. To adjust the lookback period for scan/signal makers, hold down the shift key while hitting the left or right arrow keys.
• Inverse Option for Williams %R
  The Williams %R produces values in the range 0 to 100. Some users may prefer to see the value 100 – WRP graphed in their charts so that overbought conditions appears as peaks and oversold conditions appear as valleys. A checkbox is provided to invert the formula in this way.
• New Statistic function, Mean Deviation
  The Statistics (STAT) Indicator now supports “Mean Deviation”. The mean deviation for some period is the average absolute difference from the mean (average) for each bar in the period. It is a measure of volatility during the period.
• Trading Holiday Charting Fixes
  Repairs were made in the 5.5 Rev 2 Version to fix problems related to elimination of trading holidays from intra-day charts. The mouse feedback function now works properly when pointing the mouse to a period of time following a trading holiday. Intra-day downloading problems were corrected as well.
• Exporting Technical Indicator Values
  The traditional chart popup menu has a new menu item “Export Indicator”, used to export the time series of values for the selected technical indicator to a text file. The text file will contain a ticker, date/time stamp, and a numeric value of the indicator at that date/time. The ticker symbol in the export file will be in the form XXXX_YYYY where XXXX is the ticker of the underlying instrument and YYYY is a token representing the indicator exported. For example if you have a five minute chart of IBM with a moving average indicator, select the indicator by clicking on the moving average line, then right-click in the chart to access the popup menu and choose “Export Indicator”. The exported text file will show the five minute values of the moving average. The exported ticker in each line of the exported file will be IBM_MA, in this example. You can export any technical indicator value series this way, including custom indicators. The data can be imported into IRT (using File: Import) for further study using other indicators. You must define the ticker IBM_MA to Investor/RT before importing. We suggest you use “Cash” as the security type of the imported instrument so that Investor/RT will not request data from your data service on such instruments. The export file can, of course, be opened directly by Excel for further analysis also.
• New Database Utility Functions
  New database initialization utility functions have been added to the Control: Database Utilities menu. These utilities can be used to eliminate all intra-day, or daily/weekly/monthly data from the database, i.e. to start with a clean historical database. The advantage of these utility functions is that they work properly even on a corrupted database. So if you find yourself with a corrupted database and no backup, these utilities may be able to restore integrity to the database if the corruption was related to historical data. All other database content (tickers, charts, scans, quote pages, etc.) is unaffected by these utility functions, only the historical data is wiped clean.
• Traditional Chart Session Labeling Option
  Intra-day traditional charts have a vertical line marking the beginning of each session. These session marker lines are labeled at the top and bottom showing the day of the week, the day of the month, the session ending time (at the left) and the session begin time. If you do not wish these text labels to appear in any of your intra-day charts for some reason, you can uncheck a box in Setup: Preferences: Charts: General. The session marker lines will then appear sans text labels.
• UserData Text length increased
  The "User Data" column now supports arbitrary user text up to 255 characters in length. Formerly, this quote page column was limited to only 23 characters. The expanded textual data can be displayed in quote pages and chart annotations, and the content of this textual field can be searched using RTL text pattern matching.
• Multi-line user data in quote pages
  In order to view longer text content in the user data field in quote pages, we have added a "mutli-line display" option for quote pages. When multi-line display is in effect for a quotepage containing the "User Data" column, any row in the page that contains user data text that is too long to be displayed in the cell will cause that row to expand in height to show up to 3 lines of word wrapped textual content at one time. You can, of course, widen the column to show more text at one time. If you wish to edit the content of a user data cell, clicking in the cell will display scrollbars inside the cell so you can scroll longer texts into view for editing in place. This field now supports paste of up to 256 characters from the clipboard. For example, you can use the Web Research feature of Investor/RT to grab textual commentary from web pages and paste these into the user data field so they will show up in your quotepages.
• New Quote Page Columns, Sector, Industry
  Two new textual quote page columns and corresponding RTL tokens have been added for organizing tickers by sector and industry group. The RTL tokens are SECTOR and INDUST. These text columns are filled by the Quote.com data service (see below for download instructions), or these fields can be setup by manually entering text into these columns in a quote page. File: Import (Current Quotes/Other Data) also supports importing text into these fields if you can obtain industry/sector data in an ascii text file. The columns can then be used to sort quotepages by industry or sector, or you can use the RTL tokens to qualify scans based on industry or sector. For example, the scan:
  
  CL > MA AND SECTOR = "*Technology*"
  
  Will list all instruments having the word "technology" anywhere in the sector description that also closed above the moving average specified by MA.
• Quote.com Download Options Added
  Users of the Quote.com service have two new options in the Data Download window. Download types "Company Names" and "Fundamental Data" are now supported. The Company Names download can be used to fetch the instrument description (security name) and the industry and sector where applicable for individual tickers or a list of tickers in some quotepage. This feature provides names for futures, options, and indexes also. The Fundamental Data downloaded retrieves a variety of fundamental items for any list of stocks. These include the following data items, all of which have corresponding RTL tokens:
  
  Money Flow, VWAP, Dividend, Beta, Float, Shares Outstanding, Institutional Ownership, Cash Flow per Share, Return on Equity, Return on Assets, Gross Margin, Revenue per Employee, Earnings per Share, Revenue Growth Rate, Book Value per Share, PE Ratio, Dividend Yield, EPS Growth Rate, and Industry Code.
  
  The fundamental download also fills in the instrument name, industry and sector names. This feature works best after Investor/RT has been connected to Quote.com for a minute or so and the subject quote page has been opened already.
• New Backtesting RTL token TNUM (Trade Number)
  The RTL token TNUM can be used in a Trading Signal to determine, during backtesting, how many trades have been entered into for the instrument being backtested. TNUM will be zero at the beginning of the backtest for each instrument indicating no trades have taken place yet. Each entry into a new long or new short position will cause TNUM to be incremented by one. If a "Buy More" or "Sell More" rule is triggered to add to an existing position, TNUM is not incremented. This token enables a trading system to consider whether any trades have yet been executed during the backtest of the instrument and/or how many trades the system has triggered thus far.
• Clearing User Data
  The SET command can be used in a scan to clear (eliminate) the user data for all instruments in any quote page. Use the scan formula:
  
  SET(USERDATA, CLEAR)
  
  The CLEAR token is a special numeric constant token added to RTL just for this purpose (the SET command needs a numeric value even though USERDATA is a textual, not a numeric, token. Investor/RT responds by eliminating the USERDATA text for each instrument in the scan subject quote page. The numeric value for CLEAR is 25327 which just happens to spell out C L E A R on the telephone keypad. Setting USERDATA with any other value has no effect on the USERDATA.
  
  USERDATA can be imported into a quote page from an ASCII text file. Use File: Import. Set the import type to "Current Quotes/Other Data" and specify an import format containing, for example, ticker and user data. The text file would look like this:
  
  AAPL, user data for Apple Computer
  MSFT, user data for Microsoft, inc.
  IBM, user data for IBM corporation
  ...
  
  The user data in the import file can be up to 256 characters in length, but the text cannot contain either commas or tab characters. If a comma or tab is present in the user data text, Investor/RT will not import text past that point for that instrument. In the example above the user data imported for MSFT would be "user data for Microsoft". The ", inc." would be dropped.
• CCI Commodity Channel Index algorithm revised
  The CCI indicator calculation involves the calculation of a typical price each bar. The method Investor/RT has been using for this involved averaging the highest high and lowest low in the CCI period with the close of each bar. This typical price is then further used in the calculation. For details see the description of the CCI indicator on the Linn Software web site. To bring Investor/RT into conformity with Donald R. Lambert's original writings, the algorithm has been revised to use High + Low + Close of each bar as the typical price. This change results in CCI values that match CCI calcuations we have cross checked with other sources.
• Oscillator Option Added to Parabolic SAR Indicator
  A new checkbox labeled "SAR Oscillator (CL - SAR)" has been added to the Parabolic SAR Indicator preferences.  When this option is checked, the oscillator will be drawn as a histogram that oscillates about 0.  The oscillator represents the difference between the closing price and the SAR indicator value. SAR rules would dictate entering into a long position when the oscillator crosses above 0, and reversing into a short position when the oscillator crosses below 0. 
• All User Variables Saved in Database
  Prior to Version 5.5, users variables V#1 through V#6 were the only user variables whose values were kept permanently in the Investor/RT database. All other user variables were considered "temporary" and their values were set to zero each time Investor/RT started. In Version 5.5, all user variables, V#1 through V#512 are retained on the Investor/RT database so you can now rely on these values being retained when you quit the program.
• View, Rename, Delete Window Enhanced
  The View, Rename, Delete window is now resizable allowing you to see more items at one time or to widen the list of objects when viewing longer names. Technical indicator presets are now sorted alphabetically like all of the other object types. A pushbutton labeled ">" was added to the right of the object type menu for quickly cycling through the list of object types and the associated list of names for each object type.
  
  View, Rename, Delete Window can be opened in a variety of ways. First, it can be opened using the Control Menu. The Delete menu item is under the Data Management submenu. It is more convenient to use the main toolbar. When you click the trash can icon on the main toolbar, Investor/RT looks to see if the front window is an object you can delete (or rename), e.g. a chart window, and if so it asks "Is it okay to delete ...?". If you click the Delete button in reply, the chart window is closed and deleted from the Investor/RT database. If you click "Rename", the View, Rename, Delete Window opens. If you click the trash can icon on the main toolbar with no window open or with the front window containing an object that cannot be deleted, then the View, Rename, Delete window opens immediately without any prompting. Similarly, shift-click on the trash can button on the main toolbar, to open the window immediately. This window has gained more functionality over time and has become a very useful facility for reviewing the objects you have saved in the Investor/RT database, renaming or deleting items as you wish.
• RTL access to Historical Retention Periods
  Investor/RT maintains a default historical data retention period for daily, weekly, monthly and intra-day historical data. In addition, each instrument can either take the default settings or have an override period different from the default. Setting the defaults and overrides for an instrument can be accomplished in Setup: Preferences: Historical. In version 5.5 tokens for these settings have been added to the RTL language and new quote page columns are now available to display the retentions periods for each instrument in a quote page. The RTL tokens are HRD, HRW, HRM, HRI for "Historical Retention" Daily, Weekly, Monthly, Intra-day respectively. The quote page columns have column titles that begin with "Retain", e.g. "Retain Intraday".
  
  While this feature may not be widely used, it does enable the historical retention preference setup to be automated using scans and the SET command. For example, suppose the default intra-day retention period is 10 days, but you wish to adjust all of your futures contracts so that 60 days of intra-day data will be retained while leaving all other instrument types using the default of 10 days. While such an operation can by done manually using the Setup: Preferences window, it can more easily be accomplished using a simple scan:
  
  IF (SECTYPE = SEC_FUTURE) THEN SET(HRI, 60) ELSE SET(HRI, 0)
  
  Notice that setting HRI to zero means to set the intra-day retention to the default value. Scans can similarly be used to find which instruments have certain retention properties, e.g.
  
  HRI != 10
  
  Assuming 10 is the default HRI value, this scan finds all instruments that currently have an intra-day retention period different than the default value of 10, i.e. if finds all of the overridden instruments.
• Quote Page Refresh Options
  Investor/RT 5.5 introduces a new quotepage option for update frequency. Two options are provided in the preferences, (1) dynamic and (2) Every N seconds. Dynamic updating simply means that every incoming tick for a visible ticker in the quote page will be reflected in the quotepage as the tick arrives. This is how earlier releases of Investor/RT have always worked. Dynamic updating of quote pages consumes considerable resources, especially for quote page where many more instruments are present than are visible. Even when a few very active issues are present in a smaller quotepage, a great deal of unnecessary processing may be taking place when say 20 or 30 updates are hitting the quote page every second or so. Choose the "Update Every N Seconds" option to reduce the screen flicker and processing overhead associated with active quote page updating. Some Investor/RT users have a quote page of several hundred instruments open essentially for the purpose of "watching" (activating) that list of instruments with the data service. Such pages may be even minimized much of the time. Setting such pages to update every 60 seconds can eliminate a major drain on the processor.
• New RTL Tokens BPS, MPB, MPS
  BPS provides the number of bars in the trading session based on the session of the instrument. MPB provides the number of minutes in a bar. MPS provides the number of minutes in the trading session of the instrument.
• Signal/Signal Marker Enhancements
  You can now specify an offset in pixels to be used when a scan/signal marker is drawn in the chart. This option will be useful if you have several marker indicators in the same chart window pane. By giving each one a distinct offset, the markers will "stagger" when two or more signals happen to true for the same bar. The offset can be set manually in the setup or you can select the marker in the chart window and use the keyboard up/down arrow keys to adjust the offset. The left and right arrow keys can be used to shift the marker placement left and right. A "Show Price" checkbox is provided for further annotating the marker with either the last, high, low or date/time of the bar on which the signal triggered.
• Color Marker Enhancement
  The Color Markers indicator now has a "Vertical Line" choice for the shape of the marker.
• Custom Profile Enhancements
  Custom Profile Chart preferences now have a manual scaling option for the horizontal scale. Minimum scale value and maximum can be independently adjusted. Double-clicking on a ticker in a custom profile performs multi-linking properly when the "double-click" action preferences calls for multi-linking.
• Fibonacci Retracement "Live" Options
  The preferences for Fibonacci Retracements has a "Live" checkbox. When checked Investor/RT draws a line at the right showing the actual percent retracement level of the current bar.
• Bar Count Option for Scans/Signals/Custom Indicators
  Scans, trading signals, and custom indicator setups now have a user preference for the number of bars of data to be used to calculate the formula. The default setting is "Automatic" meaning that Investor/RT will determine how many bars of data are needed based on an examination of the formula tokens and technical indicator setups. There is also an "All Data" choice meaning that all data on file for the instrument will be used. Finally, you can specify a specific number of bars to be made available to the scan calculation. Here is an example that may help clarify how this new Bars Option is used. Consider a scan (5 minute periodicity) that looks for CL > EMA where EMA is a nine period exponential moving average. If you specify Automatic, Investor/RT will attempt to fetch nine 5-minute bars. If you specify 20 bars as the bar option, Investor/RT will attempt to fetch 20 bars even though it only needs 9 to actually compute the EMA. If there are 9 or more bars available, those bars, but no more than 20 will be made available to the scan for calculation. Generally speaking the calculation will take less processing time if the automatic setting is used since only the minimal number of bars will be used in the calculation. Some indicators, like EMA, can benefit from more bars since there are cumulative effects in their calculations.
  
  The new bar option can also make scans run much more efficiently in some circumstances. Suppose you have a scan that uses the DV token to fetch the closing price at a particular time early in the trading session. When the DV token is used in a scan, Investor/RT by default fetches all data on file for the periodicity involved and searches that (possibly large) data collection for the bar it needs. However, if you know that the bar you are looking for is always in the current trading session you may specify a specific number of bars, e.g. 390 one-minute bars. This will tell Investor/RT to look at the most recent 390 bars instead of the thousands of bars you may have on file for prior trading sessions. Thus this scan will run considerably faster, especially if DV is used in conjunction with other more mathematically complex indicator calculations since indicators utilize the increased numbers of bars also.
  
  In the scan setup window, pressing the check button will show you the number of bars Investor/RT has determined are needed for calculation. If you specify an overriding bar count that is less than the calculated requirement, the calculated requirement will always be used.
