Hi all!

I have a question about using an EA on multiple timeframes and multiple currency pairs. I have been developing and testing an EA for a while now, and it seems to work quite well on pretty much all currency pairs and also on three different timeframes that I#8217;m interested on. EA is now made to work just on a one pair and one TF, so I have been optimizing live testing it separately on every chart. But, since it#8217;s method is quite strict, it trades quite rarely. And because of this, I would like to use it with all 28 pairs I#8217;m using, and with 3 different TF#8217;s for every pair, that is 84 charts in common. And of course it is not so easy to manage 84 different charts in MT4#8230;

So my question is; how would you solve this problem? Would you develop an EA that opens trades on multiple pairs, on multiple time frames, or even both of them (= 1 EA instance for all 84 pairs)??

Pros/cons I can see for these options are:

EA that trades on all timeframes, but just for one pair:
#8211; Still 24 charts open
#8211; Every pair should still be optimized separately
I can still visually check from a chart if the trade was taken on a right time, same indiors can be seen on all TF#8217;s on a chart

EA that trades on all pairs, but just on one timeframe:
Only 3 charts open, one for every TF
Optimization could be done for all pairs at once
#8211; Trades cannot be visually confirmed from a chart (or they can, but only for the pair that EA is attached on) quite a big risk for errors

EA that trades on all pairs and all timeframes:
Just one chart open, easy to manage
Optimization could be done for all pairs and all timeframes at once (if wanted)
- Trades cannot be visually confirmed at all from a chart (or they can, but only for the pair TF that EA is attached on) quite a big risk for errors

Any comments?
