FEATURE HIGHLIGHT 6.35

6.35 provides:

  1. huge speedups in running huge explorations,
  2. dark theme and 5x speed up for rendering huge list views like (as compared to 6.31)
  3. improved Batch functionality – clipboard support (copy/paste of selected batch items), new optional parameters for batch commands
  4. new AFL functions (SafeDivide, erf(), inverf()) and AFL parser improvements

CHANGES FOR VERSION 6.35.0 (as compared to 6.31.0)

  1. AFL: new function inverf(x) – inverse of erf function
  2. AFL Editor: added function navigation combo box in the toolbar – detects user defined functions and allows to quicky navigate to function definition
  3. AFL: GetOption(“PadAndAlignToReference”) allows to query Pad and align setting status (note that this is read-only field, so it will not work with SetOption)
  4. AFL: new function erf(x) – computes Error function https://en.wikipedia.org/wiki/Error_function
  5. AFL: parser warns if empty body is used in ‘for’ statement, like this: for( i = 0; i < 10; i++) ; // extra semicolon at the end - empty body Warning 510
  6. AFL: parser warns if empty body is used in ‘while’ statement, like this: while( condition ) ; // extra semicolon at the end – empty body Warning 510
  7. AFL: SafeDivide( x, y, valueifzerodiv )- safe division that handles division by zero using special handling (replace result with user-defined value)
  8. Batch: added optional parameter to Data Import ASCII command to allow specify format definition file
  9. Batch: added optional parameter to Execute and Wait command to specify current working directory for command
  10. Batch: added optional parameter to Export to File / Export walk-forward to file to specify column separator in CSV files
    -optional parameter defines the column SEPARATOR used for export. Only single character is used. When it is not supplied, comma is used.

  11. Batch: Clipboard Cut/Copy/Paste implemented in batch editor
  12. Batch: Edit->Delete (from main menu) and Edit-Delete All implemented for completeness
  13. Batch: list view uses virtual mode now (owner data)
  14. UI: All owner-draw list views (NOT in dialogs) now feature customizable theme (currently available “system (light) theme” and “black theme”) – go to Tools->Customize, “Appearance” tab, “Dark mode for listviews” checkbox
  15. UI: Analysis and RT quote window use now exactly the same RGB values for up/down (green/red) colors for consistency
  16. UI: Custom virtual listview (owner data) supports per-item data now
  17. UI: Found workaround to avoid terrible flicker and bad rendering of list view controls during fast page up/down and side scrolls (even though they are double buffered by Windows and in theory should be smooth).
  18. UI: Identified even more bottlenecks in Windows OS that caused even owner data and owner draw Listview performance to suffer with large number of columns. OS code circumvented. Listview redraw speeds increased more than 5x compared to previous speedy implementation
  19. UI: Implemented resizing of Listview column customization dialog

CHANGES FOR VERSION 6.31.0 (as compared to 6.30.0)

  1. AFL: Access violation in PercentRank when period is wrong. Now error 52 is displayed instead.
  2. AFL: InternetPostRequest now silently (or with warning 507 under debugger) returns NULL handle instead of error when remote server responds with HTTP Status 50x
  3. Analysis: manual column re-sorting could be bit off if scientific output format (xxxEyyy) was used with different exponents. Fixed.
  4. ASCII importer now handles LastSplitRatio of X:Y where X and Y are 1…32767 (previously only 1..127)
  5. Batch: add “add results to watchlist” action / WatchlistAddResults
  6. Batch: add “clear watchlist” action / WatchlistClear
  7. Batch: add “comment” action
  8. Core/DB: fixed access violation when all data were removed while QuickData was turned on
  9. DebugView: eliminated some internal messages from DebugView output (from release version)
  10. InternetPostRequest – even if URL started with https, previous version wanted to connect to port 80, instead of 443. Fixed.
  11. UI/Listview: since 6.28 exception could occur if single cell text length exceeded 1024 characters. Fixed.
  12. When database is empty, ticker box displays grayed text instead of blank or reminiscent of previous database symbol

KNOWN ISSUES:

  1. None
