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.

via new PlotVolumeOverlayA function

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:

TickSize defined in the Symbol Information, if its value is zero,
then 1R would be equivalent to 0.01 movement (for backward compat)

reference ALL bars

to detect special executions states

clicked in attempt to resize and released in the very same position
(without moving the mouse). Now it is fixed.

RANGE bars in TickSize units (as opposed to mode 3 that uses dollars
for backward compatiblity)
