Love the new Quick AFL support! It improved my execution time from 41sec to 25sec for each optimization pass. It will shave hours off each walkforward step.
The new optimizer is a also a huge improvment and makes walk forward testing practical. A couple of questions for you: Is the full array still passed to a DLL, or just the part of the array that Quick AFL is using? It looks like the full array. Is there any way that a dll can tell what part to use/ignore? Keep up the great work. Ami has taken a giant leap foward in the last few months. --- In [email protected], "Tomasz Janeczko" <[EMAIL PROTECTED]> wrote: > > Hello, > > AmiBroker 5.14.0 BETA is released now: > http://www.amibroker.com/devlog/2008/07/04/amibroker-5140-beta- released/ > > CHANGES IN VERSION 5.14.0 (as compared to 5.13.0): > > 1.. added support for Quarterly and Yearly intervals in all parts of the program > 2.. Changes to drawing made in v5.13 caused improper drawing lines located PAST the last available quote (trendlines and pitchforks) when timestamping method was "START TIME of interval". This is fixed now. > 3.. Fixed AddSummaryRows so 'onlycols' parameter default (zero) is applied properly > 4.. Implemeted "Select all" via Ctrl-A keyboard shortcut for all list (result list in AA for example) > 5.. Mouse cursor shape (moving/sizing) reflects the selected study priority when more than one study exists under mouse position > 6.. new multiple Volume At Price charts at user-defined points via new PlotVolumeOverlayA function > 7.. QuickAFL can now be used in Automatic Analysis (Settings: General: "Use QuickAFL" - check this box) - this can speed up explorations, scans and backtests by factor of 2+ if range is less than "all quotations". More on this: http://www.amibroker.com/kb/quickafl > 8.. Range Bars compression now uses TickSize as "1R step".

Status("ActionEx") provides more codes than Status("action") to detect special executions states > 14.. Streaming chart update could stall if trend line handle was clicked in attempt to resize and released in the very same position (without moving the mouse). Now it is fixed. > 15.. TimeFrameMode() now supports mode == 4 - which expresses RANGE bars in TickSize units (as opposed to mode 3 that uses dollars for backward compatiblity) > 16.. when display chart timing option is turned on and RT stream is active the application STATUS BAR now displays TOTAL time for all charts, it should be BELOW 1 second for RT trading > > Best regards, > Tomasz Janeczko > amibroker.com >
