                                 CHANGE HISTORY
                                 --------------

Version 1.5 -- Released November 22, 1993
       -Added "action conditions" to the definition of a study.  A study can
        include up to 6 "actions" such as Price Painter(tm), Mark It(tm), and
        Audible Alarms which will appear on a chart depending on the user 
        defined conditions and the price data being charted with the study.
       -Now permit the Data Microscope to work on any chart. 
       -Added six new indicators:
                DPO(p) - Detrended Price Oscillator
                MASS(p) - Mass Index
                MOV(d, p, TRI) - Triangular Moving Average
                MOV(d, p, VMA) - Variable Moving Average
                PDO(d, p) - Price Deviation Oscillator
                VHF(d, p) - Vertical Horizontal Filter
       -The Print Tool can now print multiple charts on a page and prints 
        different sized charts.
       -Automatically print colored chart backgrounds as white.
       -Now permit scalars like MAX(C) to be used in all the functions.
       -User can now set the Y-axis to automatically rescale on zooming (from 
        the Chart Preferences form) and perform a manual rescale if the chart 
        is scrolled by clicking again on the + or - Zoom Tools.
       -Added the ForLoop(expr, to, from, step; initExpr, proc?) function.
        The ForLoop() function permits the user to define self-referential
        expressions and embedded FOR LOOPS which can be included in any 
        formula or algebraic expression.
       -Added automatic detection of Close Only data which is automatically
        plotted as a line chart instead of HLC bars.
       -Added the Fibonacci Time Zones tool to the Pointer Menu.
       -Added the Percent Retracement tool to the Pointer Menu.
       -Can now read CSV ASCII files that are in British Date Formats, 
        i.e. DD/MM/YY.
       -Preserve the format of the date field for CSV ASCII files when 
        performing data maintenance on them.
       -Fixed the Study Editors so that they overlap.  This minimizes redraw
        but may cause a problem with system resources in some setups, 
        especially with Windows 3.0.  We strongly recommend using Windows 3.1.
       -Added "Set All To Black" button to the Color Editor.
       -Added a "Sort New Group" button the the Create/Modify Group form.
       -Maximum number of charts that can be displayed at one time is now 24.
       -Added five new Share Purchase methods to the profit tester.
       -Added "Daily Details" button to the detailed profit test results form
        to display daily results for all prices, formulas, conditions, buy
        and sell rules etc.
       -Added a Clear button to scans and profit tests.
       -Now permit column sort radio buttons in Scan to be deselected.
       -Now retain the sort order in a group created from a scan.
       -Fixed it so a scan must be selected before one can be run.

NOTE: The MANUAL.TXT file and the help files have had to be trimmed in order 
      to permit the zipped version of Parity to fit on two 360 KB disks.  
      The printed manual registered Parity users receive includes more than 
      25 pages on the definition and interpretation of the predefined 
      technical indicators and is lavishly illustrated.
