How to run a back test of 7 charts same EA but different settings in each chart?

 


Hello, 

I have tick data suite, and know how to run a back test by date, with different set file, different balance, change the spread, watch in real time, skip foward,inspect the results.

What i would like to be able to do is for example take 3 charts, same EA, make EA slightly different in max lot amount tradeable and then run a back test with all three putting their results towards that months test. 


I have seen some one back test a "portfolio" of "strategy",

How do we do this for MT4 and a market place EA?

Thank you for any assistance ahead of time.


Regards, 

Bud
