Single curtrency to Multicurrency EA Conversion

[Peter Kaiza]

How do I turn a single chart EA  to a multiple chart EA?

e.g, the EA is normally attached to 3 charts EURUSD, GBPUSD and USDCHF on  mt5 terminal.

The problem comes when you're looking at testing on the three symbols simultaneously on the visual tester.

Problem is on each recall of the indicators on the original EA, how do you amend the Symbol() part to look for more than one symbol?

Is there an easy way around this?

Thanks.
