1. New Scan Functions
   New Scan Functions Several new statistical and arithmetic functions have been added to the scan request language. The statistic functions MIN, MAX, AVG, and STD calculate the minimum, maximum, average, and standard deviation for some period. These functions take a single parameter which can be any historical data value (CL, HI, LO, etc.) or any technical indicator (RSI, CCI, MACD, etc.) qualified by a number to indicate the number of periods to examine in computing the result. For example:
   
   MIN(CL30) yields the minimum closing price in 30 periods
   MAX(RSI5) yields the maximum RSI value in 5 periods
   STD(VO20) yields the standard deviation of trading volume in the last 20 periods .
   
   Notice that the statistical functions, unlike arithmetic functions, must have only a single token and numeric qualifier as a parameter. Expressions like MIN(HI5 -LO5) are improper since HI5 - LO5 is not a single token.
   
   A new arithmetic operator, LOG, has been added to calculate the natural logarithm of any numeric expression. For example:
   
   LOG(HI5-LO5) will calculate the log of the high/low range 5 periods ago.
   
   Arithmetic functions now include:
   
   LOG natural logarithm
   ABS absolute value
   SQRT square root 
   
2. New Markers In Chart Window
   A new technical indicator called "News Marker" can be added to chart windows. This indicator examines the news items on file for the charted instrument and displays a visual marker in the chart window for each bar that has an associated news story. The selection of marker and marker color is similar to the scan technical indicator for marking scan signals. When a news marker appears in the chart, point the mouse pointer at the marker and the headline of the news items appears in the message area of the main toolbar. Right click on the marker to access the settings for the news markers. The settings dialog has a button to access a news browser for the charted instrument.
   
3. Trading Notes Markers
   Similar to news markers, the new trading notes marker indicator places markers on the chart for each bar that has an associated trading note. When you enter trading notes for an instrument you can specify the exact date and time of the note. Whether you are viewing a daily or intra-day chart the marker will be placed on the bar with the closest date time of each trading note.
   
4. New Marker Images
   Several new marker images have been added. These markers can be used in the scan technical indicator, or the new indicators for news and trading notes discussed above. The new marker images are: triangle, letter N, letter T, flag, and exclamation point. The letter N and T markers were added for use with the news and trading note indicators.
   
5. Historical Data Compression
   New commands have been added to the Control: Data Management menu for compressing the tick data and daily/weekly/monthly historical data files to their minimal size. The database management system used by Investor/RT does not reduce the size of database files when data records are deleted. Deleted record slots remain in the database available for re-use. The Compress Tick Database command exports all tick and intra-day bar data to a single text file and then creates a new tick database files and imports the exported data back into the database. This results in a smaller tick database with no deleted record slots. The Compress History Database works similarly on daily/weekly/monthly data. The exported text files are placed in the admin directory. They are not deleted after the process has completed. These file may be deleted by the user or retained for backup purposes if desired.
   
6. Scan Setup Window Enhancement
   In the scan setup window, a list button of scan tokens has been added in space of the token button. The new list button contains all user specified tokens listed first, followed by all built-in function tokens (ABS, LOG, MIN, MAX, etc.). To insert a token into the scan request text area select the token you want from the list. An "undo" choice is also available to undo the most recent action. When adding functions from the token list, Investor/RT inserts the token followed by left and right parentheses and places the text entry cursor between the parentheses. You may then type in the parameter or use the token list to insert the parameter to the function.
   
7. NASDAQ Level II Support for DTN
   Level II screen are now available with the DTN data feed. A high speed serial connection is required for receiving level 2 data from the D8000 receiver. A DTN connection of at least 230400 is recommends, 460800 BPS is preferred. If your serial port is unable to communicate at these higher speeds an add-in high speed serial card is recommended.
   
8. Order Desk (Place Trade) Enhancements
   In anticipation of connecting Investor/RT to electronic trade execution systems, the order desk dialog has been enhanced in a variety of ways.
   
   First, accessing the order desk for a particular instrument has been made easier by adding "Place Trade" as a menu choice in the pop up menu in charts, quote pages, portfolios, and quick quote windows. The pop up menu appears when you click in a chart window, or right click on a ticker in a quote page, portfolio, or in any "instrument selection" dialog. When accessed in this way, the order desk window opens with the desired symbol selected in the order desk's instrument selector.
   
   Second, the order desk is now live. The window title updates dynamically showing the last, bid, and ask price as trades occur on the selected instrument. The last price and tick volume also appears inside the window and updates as trades occur, e.g. "IBM Last 114 5/8 x 1000."
   
   The order desk now defaults to "market order" and opens with some of the non-required entry fields out of view. When the user wishes to make a journal entry or trade entry into the portfolio, the window automatically expands to show the other data entry fields, e.g. trade date/time, commission amount, etc.
   
   As controls are operated in the window. Investor/RT shows an abbreviated description of the trade, e.g. Buy 1000 IBM (New Position) or Sell 500 MSFT (Short Sale), or Sell 500 AAPL (Exit Short). The trade description appears just beneath the "Place the Order" button to make it clear what action is about to be performed.
   
   The Quantity entry field is now an "Edit List Box". This means that trade quantity numbers can be entered manually by the user or selected from a menu of frequently used quantities. For equities, the menu list has 100, 500 and 1000 choices, For other instrument types, choices of 1, 5, 10, and 100 are listed.
   
   Finally, all instrument selectors, including the one in the order desk dialog, now have a pop up menu that allows the user to switch the instrument selector to an alternate list of instruments. The first choice in this pop up menu is "Trading List". By creating a user defined quote page with the name "Trading List", the instrument selector in the order desk window will always open with those instruments displayed. If there is no Trading List quote page, Investor/RT will show all instruments. Thus the "Trading List" quote page can be setup with a short list of candidate issues to facilitate trade entry. You can drag and drop symbols from other quote pages into the trading list quote page and save the revised trading list at any time. Then choose trading list from the pop up menu to see the revised list in the order desk. Another advantage to the "Trading List" feature is that the order desk will list the instruments in the sequence they are listed in the actual "Trading List" quote page. Thus, you can position the instruments most frequently traded at the top of the trading list. While the order desk window is active, you can right click on the instrument selector title row to access the pop up menu of other available instrument lists. On Macintosh, a right click is accomplished by holding down the command key while clicking.
   
   The Order Confirmation window has been renamed "Order Status". This window is still used to manually confirm filled orders as before. When trade execution capabilities are added to Investor/RT this window will show all submitted orders and their status until they are confirmed electronically.
