CHANGES FOR VERSION 5.68.1 (as compared to 5.68.0)
- 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

- 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
AmiBroker 5.67.1 BETA
- Low-level gfx playback engine resets colors to black pen / white background, so it does not get influenced by chart colors like labels.

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.
- Charting: a new “Warning 902 can not plot a chart in logarithmic scale as a data set contains negative value(s)” message is displayed on attempt to use log scale with negative data and the chart is plotted in linear scale instead.
- 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.

- AFL: PlotShapes() now has XShift parameter
- Custom metric optimization target (WF tab) is now matched case-insensitive (FC#2442)
- 32-bit and 64-bit versions now use different registry key to save list of DLLs so warning messages about non-certified 3rd party plugins are not displayed each time you switch between 32-bit and 64-bit app version anymore.
- Foreign(“~~~EQUITY” ) within custom backtest proc in old AA returned zero (because of change in 5.65). 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).
- New Analysis: when SetSortColumns was used in 5.63 and above it could trigger redundant multiple sorts. Now it is fixed (sort only once)
- 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)

- 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
- Time&Sales allows to customize colors (separate color setting for trades occuring above/at ask, inside, at / below bid, etc). Right-click and use context menu to bring up “Colors…” dialog. FC#2313
- Time&Sales now supports “Wide list” mode in addition to existing “Narrow” mode. “Wide mode” has separate columns for bid / ask data. To switch – right click on the T&S window and choose “Wide” or “Narrow” from context menu. FC#2332
- GetFnData() supports now “Currency” and “WebID” fields
- AFL: some transcendental math functions (sqrt, sin,asin, cos, acos, tan, atan, ln, log10, etc) are 10-30% faster now.

- 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
- Per-symbol UserData fields are accessible now via GetFnData(“UserData0”)..GetFnData(“UserData99”). This feature is for implementors of custom data plugins to allow them to expose custom data

- Floating window caption is now synchronized even if it is not active (FC#2376)
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)
- ASCII importer now supports $WEBID command and WEBID field in the $FORMAT command to allow importing web ID (FC#2362)
