Where/How to backtest a strategy with multiple charts?

Hi I see this message in Pseudo code

IMPORTANT – BACKTESTING ISSUE IN MT4 DETECTED WITH THIS EA !
//|
//| Your strategy contains multiple charts, or multi-symbol / timeframe
//| blocks or indicators – an example is Open Daily, Low Daily, etc.
//|
//| MetaTrader 4 Strategy Tester doesn’t support multi-TF or multi-symbol
//| strategies, so this strategy will be not backtested correctly.
//|
//| MT4 supports trading of such strategies, but not their backtesting,
//| unfortunately there is no known way to backtest these strategies in MT4.

If i have generated a startegy to trade eurusd whilst looking at the eurgbp and gbpusd how can i reliably backtest it? or this this statement  above wrong?

Thanks

Oliver

Hello, the message is obsolete. You can use MT to backtest multi-symbol & multi-timeframe strategies

ok thanks

i dont think so, that its so simple

in MT4 we can backtest only multiTF strategies looking at the higher TF

no multimarket, no multiTF with lower TF

You can check this

Trade EURUSD based on GBPUSD close bar above / below its MA 14

As mentioned it is recommended to reference only higher (multi-tf) or higher/same timeframes (multi-symbol)
