Im curious as to how multiple indicator windows function in
terms of threading - could you comment on how multiple cores will or will not
affect their performance?
TIA

No I did not mean
that. I am simply more focused on delivering
problem-free software than
meeting some artificial deadlines
but end of march is still
realistic.

That depends on how long single backtest step runs but
it should
be reaching 2x with most complex formulas.

As for AB - it was discussed earlier. Most parts use single thread.
