CHANGES FOR VERSION 5.43.1 (as compared to 5.43.0)

1. When range different than "All quotes" was selected, backtest in new Analysis window could produce incorrect results in 5.43.0. Fixed.

CHANGES FOR VERSION 5.43.0 (as compared to 5.42.0)

1. New Analysis Window: multi-threaded Backtest feature implemented (experimental)
2. Load/Unload buttons removed from Plugins dialog.
3. ListViews: the last line (partially shown) in RT quote window was not easily selectable. Fixed
4. New Analysis window: Implemented Parameters dialog
5. AFL: GetCursorMouseButtons() sometimes missed clicks when multithreading was on and formula took ages to execute. Now it is now 100% reliable.
6. Auto-selection of proper layer based on selected viewing interval
7. IRA accounts support - implemented Settlement delay in backtester, via SetOption("SettlementDelay", x )
8. Zoom in/out toolbar buttons zoom in finer steps (+/-10%)
9. Analysis ListView, RMB menu new option: "Add Rank column" - adds a column with ordinal rankings based on current sort or just row number column when list is not sorted
10. New feature: Adding new chart/research/account/analysis via (+) tab
11. New Analysis window: Implemented SetSortColumns
12. New Analysis window: Implemented AddSummaryRows

CHANGES FOR VERSION 5.42.0 (as compared to 5.41.0)

1. Implemented right click menu in new Analysis windows (Add symbols to watchlist/Show arrows functionality)
2. Zoom in/out toolbar buttons now have auto-repeat feature
3. In 5.41.0 Ctrl+C from list view copied text without tabs (column separators). Fixed
4. In 5.41.0 did not refresh progress dialog optimization status list. Fixed. (owner draw list view initial size is retrieved in PreSubclass now)
5. In 5.41.0 did not display Time&Sales in reverse order (newest on top). Fixed.

CHANGES FOR VERSION 5.41.0 (as compared to 5.40.0)

1. New Analysis window (File->New->Analysis) - featuring multithreaded Scan and Exploration
   Performance note: to fully benefit from multithreading it is best to use AmiBroker local NATIVE database (not external) as it is the only database that can deliver data quickly enough. Tests show that on AmiBroker native databases scans and explorations are 100% scalable to multiple cores
   - i.e. for example would run upto 8 times faster on 8 CPU/core machine. IMPORTANT: This window is work-in-progress. Multithreaded Backtest and Optimization features will be added later.
2. Totally rewritten listview with very efficient owner draw code speeds up list view scrolling/resizing/repainting more than 10 times. Native system ListView control is terribly slow on Windows XP/Vista/7 (surprisingly it was many times faster in Win9x!)
3. AFL: AddColumn - added mini bar charts to explorations
4. Mini-chart in RT Quote window. Mini chart shows where LAST price is within LOW-HIGH range.
5. AFL: Percentile() does a param check for range > 0 now
6. Errors and warnings are now displayed in red color in the indicator pane
7. During actual GDI chart rendering AmiBroker measures time and if it exceeds 500ms timeout it stops rendering with Warning 901.
8. Warning 502: Calling Plot()/PlotOHLC over 500 times is displayed in indicator in runtime to prevent abuse
9. All list views, pressing Ctrl and NumPad'+' automatically adjusts column widths to content
10. If data are missing in the in-memory cache, Foreign() calls from non-GUI threads use synchronous retrieval method for reliability.
11. Old and new Analysis window: outputting millions of rows to listview is much faster now
12. All list views - Ctrl+A (Select All) made much faster
