Multiple Timeframe

[mpantogi]

Hello,
As i know i can with fxdreema to check for indicator prices for example in timeframe 15 min and 4 hour, but my ea will be added on 1 hour timeframe.
For this , should i have opened the other timeframes charts for the currency or this doesn't matter

Regards

this doesn't matter, you don't need to have opened other TFs

MetaTrader somehow knows the data from other timeframes. I don't know how acurate is this, but in general you can get the indicator value from M1 and H1 for example. You can also do that for different Symbol, but in MT4 you cannot backtest multiple symbols, this is some limitation of the Tester.
