Hi,
I ran your code as is, except for changing the symbol names to IB's
format. Then I enabled AB's timing analysis via:
Tools->Pref->Misc->DisplayChartTiming and yep its not the fastest bit
of code ;-} On my box it took almost 0.014 secs (14-MilliSecs) using a
a worse case 1 minute time frame. Longer time frames improve matters.
So, it show that this bit of code is hardly an AB killer, in fact it
shows just how quick AB actually is. Now if only TJ would create an
AFL compiler. Anyway, if you enable your timer your probably see a
time similar to mine. So, may I suggest you look elsewhere for the
problem, perhaps the MT3 plugin or maybe you have a really slow
computer :-)
Also, thanks for the idea of using relative currency pair strength.
