Testing multiple EAs on different pairs and timeframes at once

Hi guys,

Does anyone know of a good software for testing bundles of EAs or EAs that operate on multiple pairs simultaneously?

open multiple instances of MT4

Interesting as that idea is. I wouldn't be able to test EAs that are supposed to work together or act on multiple pair simultaneously while exchanging information.

Not that I couldn't hack something together, to simulate the effect but it would be difficult and not really fun.

I wonder if the tester in MT5 supports this. They really need multi-EA, multi-pair, multi-timeframe testing.

or

not for multiple eas but multi pairs and if you wanna use mt4....

for multi TF, just put the code below in your ea for optimization.
extern int TF =0;
if(TF==0)TimeFrame=0;
if(TF==1)TimeFrame=1;
if(TF==2)TimeFrame=5;
if(TF==3)TimeFrame=15;
if(TF==4)TimeFrame=30;
if(TF==5)TimeFrame=60;
if(TF==6)TimeFrame=240;
if(TF==7)TimeFrame=1440;
if(TF==8)TimeFrame=10080;
if(TF==9)TimeFrame=43200;
custom=iCustom(NULL,TimeFrame,bra,bra,bra)
