Tomasz,
Compliments on your rethink on QuickAFL.
(I haven't tried it yet but I'll take your word for it and assume
Fred is only having teething issues).
I wasn't excited when you released the CMA-ES optimizer since I am
not an optimizer, or a mathematician (elegant algorthims don't
necessarily turn me on, only elegant solutions to worthwhile
problems).
All is not lost, however, since I do acknowledge it CMA-ES a
pragmatic solution.
On the other hand, I am excited about the 'new' QuickAFL on two
counts.
First, a few of us prodded you about this, via the forum, and we
didn't use a sledge hammer, so you get top marks for observation,
understanding and responsiveness.
Secondly, illogic always demands a solution and the 'hung' status of
QuickAFL and the Range settingsNOT in AA were annoying illogicalities.
In my book, 10/10 for smoothing the logical construct.
Many aspects of the underpinning logic of AB are very frustrating for
me and I have to try not to let that spill over into other arenas,
which involves a lot of lip bighting on my part, but your recent work
forbodes very well for the future.
I have been waiting for this.
While age diminishes our intellectual capacities, in some minor ways,
it adds a breadth and depth that we can't achieve in our youth.
Welcome to the club!
Once again - thank you so much - EXCELLENT WORK.

This is fixed now.

is applied properly

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:

> 8.. Range Bars compression now uses TickSize as "1R step".
TickSize defined in the Symbol Information, if its value is zero,
then 1R would be equivalent to 0.01 movement (for backward compat)

because redraw is not made when selected line in higher compressed
interval remains in place

selected time compression timestamping method

reference ALL bars

engine used. Now it is fixed
> 13.. 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
