CHANGES FOR VERSION 5.69.0 (as compared to 5.68.1)
- Adding symbols via ASCII import caused change of selected symbols in charts. Fixed.
- OLE: AnalysisDoc.Run supports Individual Optimization now (Action == 5)
- Charts: when formula file can not be found the detailed information about the path referenced and current working directory is displayed instead of old "the formula can not be found - no chart to display"
- New Analysis: added Auto-repeat status icon in the right-hand corner of the Info bar (yellow 'play' arrow shows up when auto-repeat is active and scheduled for next run)
- AFL: Percentile() uses now new algorithm that has linear O(n) complexity instead of O(log(n)*n) so it is MUCH faster than the old one and close to Median() that uses quickselect (which is fastest)
- ODBC plugin: now available in 64-bit
- AFL: since 5.63 round() function used 32-bit floorf which resulted in some differnces as compared to 5.60. Previous code version is restored now.
- DDE plugin: 64-bit version of DDE plugin was producing incorrect timestamps. Fixed.
- Default seed for Random() and mtRandom() was based on time(), which could be the same for threads created in the very same moment. Now the seed in multiple threads is guaranteed to be unique. This prevents repeated pseudo-random sequences in multiple threads created in the very same moment.
- IB plugin: added support for CFDs (security type=CFD, exchange=SMART) and commodities (security type = CMDTY, exchange = SMART)
- UI: Now there are separate MRU (most recently used) menus for files and databases (File->Recent Databases, File->Recent Files_
- Removed / changed some mnemonics (key accelerators) in menus to avoid duplicates
- The default setting for Layers/"Auto-Select Layer" is changed to OFF.
- Custom Backtester interface: added FullName read-only property to Trade object (gives full name of symbol)

- Fixed crash occuring in 64-bit version when StaticVarGenerateRanks was used on large arrays.
- AFL: since 5.63 round() function used 32-bit floorf which resulted in some differnces as compared to 5.60. Previous code version is restored now.
CHANGES FOR VERSION 5.68.0 (as compared to 5.67.2)
- AFL: new function: Error("text") - allows to display user-defined error messages and stop execution of the formula. Good for 3rd party plugin implementors to display error messages
- AFL: new function: StaticVarGetRankedSymbols( "outputprefix", "inputprefix", datetime )
- AFL: new function: StaticVarGenerateRanks function (flexible ranking function, experimental subject to change - for the details and instructions how to use see the read me)

- Added millisecond support to ASCII importer. Supported time format with milliseconds is HH:MM:SS.mmm (where mmm is milliseconds 000..999)
- Unsettled sale proceeds were settled at the end of the day instead of the beginning of the next day. Fixed.
- The message 'trade not entered because of insufficient funds' is modified to mention that it also it may not be entered because of incorrect position size specified by the user
CHANGES FOR VERSION 5.67.2 (as compared to 5.67.0)
- Using more than 100 Plot() statements in one formula could cause memory corruption sometimes resulting in access violation. Fixed.
- File->New->Blank chart and then clicking "View" caused exception in 5.67.1. Fixed

CHANGES FOR VERSION 5.67.0 (as compared to 5.66.0)
- New Analysis: Optimization continued even if there was error inside custom backtest procedure. Fixed.

- UI: 'Logarithmic scale' item added to "View" menu.
- AFL: new function fdir( "wildcard", flags = 1 ) - returns comma separated directory list (like "DIR" command)
- AFL: GfxSetOverlayMode( mode = 1 ) did not work with "alternate background fill". Fixed.
- Analysis Settings Load/Save buttons were positioned wrong in RTL (right-to-left) systems. Fixed.

- Foreign("~~~EQUITY" ) within custom backtest proc in old AA returned zero (because of change in 5.65). Fixed.
- CBT: when low-level mode was used (no ProcessTradeSignals was called) ~~~Equity open interest field was not filled with number of open positions. Fixed.
When user moved default Formula path somewhere else Report charts were not generated properly. Fixed.

- Fixed crash @0048C19A/48C1C4 (click on result list after backtest to show arrows sometimes produced this).
- Foreign/SetForeign/RelStrength of the same symbol as active does nothing (i.e. refers to already existing thread local data, instead of querying database)
- In-memory quotation cache can now be larger than 20K symbols. Now the maximum is 100K symbols (user definable in Tools->Preferences, "Data" tab). Caveat use extreme values ONLY if you have plenty of memory AND you are using 64-bit version

- New Analysis: results are now sorted after Individual Optimization the same way as after portfolio Optimization
- New Analysis: Walk-forward result list colums had "alpha" type which resulted in alphabetic sort when user clicked on column. Fixed (numeric type is used now).

- QuickData did not work properly for not time-based intervals so it is now automatically turned off for charts using such intervals.
- Trade profit calculation speeded up. Upto 15% faster optimization with lots of trades.
- OpenInterest field of ~~~EQUITY symbol now holds number of open positions on bar per bar basis (works now)

- New Analysis: Multi-threaded Individual Optimization. Upto NumberOfCores faster. Note: no CBT and only exhaustive mode is supported.
- Built-in constant are set up once and shared among all threads to save setup time (gives 10% speed up in execution of simple formulas)
- Built-in constants such as colorBlack are now read-only and any attempt to overwrite such constant value results in error 55.
- New Analysis, list view in scans, explorations and individual optimizations is refreshed less often to gain some speed.
- In case of individual backtest / individual optimization the backtester allocates much smaller price cache (just for 2 symbols) - takes less time.
- In 5.63 Bar Replay did not with "QuickData" enabled (it required View->Refresh All to start working). Fixed.
- Some actions (like import of past data, split, etc) did not trigger automatic chart refresh when QuickData was enabled. Fixed.
- In 5.64.0 RoundLotSize, TickSize, and a couple of other built-in variables were incorrectly marked as read-only. Fixed in 5.64.1
CHANGES FOR VERSION 5.63.0 (as compared to 5.62.0)
- QuickData for charts implemented. QuickData is a new feature that greatly decreases time required to prepare compressed/filtered data for real-time charts.
- Time&Sales now supports filtering out trades and bid/ask quotes below user-defined size. FC#1046

- AFL: SetSortColumns() can now be called more than once to support multiple rankings via AddRankColumn
- 64-bit version: Added 'highDPIaware' and "asInvoker' settings to application manifest in x64 version, to prevent file system virtualization and scaling on high-DPI screens
- Added X/Y constaints for drawing tools. When you hold down "Y" key, start and end Y co-ordinates are set to equal value (with trend line it gives horizontal line). When you hold down "X" key you get perfectly vertical line (X start/end set to equal value). FC#1262
- When loading and saving quotation files, AmiBroker does not allocate extra memory buffer. This conserves RAM when handling large files.
- 64-bit version is able to load/save files larger than 2GB per symbol (more than 53 million data bars per symbol). Note that you would need to use huge amounts of RAM as using 50 million data bars requires 6GB of RAM or more for any decent performance.

- Snap to price now allows snapping to Closing and Opening price, to activate snap to close hold down "C" key, to activate snap to open hold down "O" key while drawing line / moving the mouse
- When "Play" button is pressed Bar replay dialog checks if Start Date is earlier than End date and displays error message if that is not the case.
- Ticker box is updated with new full name if it is changed from symbol information

eSignal: new 64-bit version allows to select whenever EOD bars should report Settlement price or regular close
- Change PlotShapes does NOT use "shape0", "shape1" variables anymore to prevent clashing with user-defined variables (#104931)
