CHANGES FOR VERSION 5.89.0 (as compared to 5.88.1)

• AFL: Performance of variable-length Sum() improved significantly in some common scenarios. Accurracy improved too.
• AFL: Sort displayed an error message if first == last even though this case is perfectly fine. Fixed (no error and no sorting of single-element array)
• AFL: Sort() with indexmode = True could cause immediate app exit in 64-bit version only. Fixed.
• AFL: when negative ‘range’ was passed to variable-length version of Sum() an application exited immediately. Fixed.
• Charts: Left/right extended Trend lines and Rays now use user-definable Extension Factor (new field in Study properties) instead of always infinite extent. Ext. Factor equal to ZERO means INFINITE, other values 0.1 … 26 define how far to the left/right line is extended
• Charts: max zoom achievable via View->Zoom Out is increased to 5 million bars, also Pref/Charting/Default zoom limit set to 5 million. Note that it is still possible to zoom to “all” quotes regardless of number of bars using View->Zoom->All
• Debug: Crash recovery window now requires to enter steps required to reproduce problem. Without knowing what you did before it is very difficult to find out the reason and fix the problem.
• Debug: Turned off remove frame pointers optimization in 32-bit builds for better stack traces
• New Analysis: Exploration: default column width is increased automatically to fit %6.2f number when there is a free space available in the right margin
• New Analysis: Optimization: when user-selected “Optimization target” can not be found in the backtest results an error 711 is displayed and optimization process is stopped
• New Analysis: trying to bring up “Parameters” window when currently selected symbol had no quotes resulted in access violation. Fixed.
• New Analysis: Walk forward tab – when you click on result list Begin/End column headers – these columns are now sorted by date instead of alphabetically.
