Herman,
Thanks for the explanation.
I would be nice to summarize this knack and your example in the UKB.
Best regards

Summarizing how off-loading Indicator code to the AA helps me:
* I don't overload my system with calculations that do not need to
be performed on each quote. For example, if I refresh my charts
10x per second but perform complex calculation only 1x per
second in the AA, I reduce my computer load by nearly 90%. The
formula is executed 1/10th as often as without the AA. Using the
AA allows me to perform complex calculations only "as often as
required".
* my indicators can keep up with more quote refreshes and my gfx
gui is more responsive, i.e., I don't miss any button clicks and
I can use requesttimedrefresh( 0.1) during live RT chart-trading
* In the AA I can separate complex calculations by TimeFrame and
further reduce computer load.
* You don't need to use the AA exclusively for Indicator support.
You can mix in short scans and explorations to the indicator
code. When I need to run longer explorations I can launch
another instance of AB and share the results by file.
* Blending the best of both Indicator requirements and AA features
I gain unique features like sorting, exporting, table displays
(using results window instead of using Title) without code
duplication.
Whenever new functions, methods, techniques, and AB resources are
exposed this always opens the door to new innovation. I am happy this
works.
Happy development,
herman
