Calling another Symbols in backtest

  • First Post: Jun 6, 2007 3:12am Jun 6, 2007 3:12am
Backtest in MT4 involves 1 Symbol only.

I understand that iClose(0) of the testing Symbol will return current Bid.

I am trying to call iClose(0) and iOpen(0) in another Symbol in backtest.
Will it return with the close of the current bar (future data because the bar is not close yet) or it is intelligent enough to return current bid of another Symbol?

Thanks

calling any information from other Symbol is not possible in backtesting.

I think it will return 0.

You can absolutely reference data from other pairs, make sure it's already in MetaTrader history though.

Yes this is true. But, the reference to other pairs will be activated with each tick of the data of the pair that you are testing.
so, what this means is, if you are testing a very slow moving pair and drawing data from a very fast moving pair, the fast moving pair will not be even accessed until there is a tick change in the backtested slow moving pair..

At least that is how I understand it... Telsa, correct me please if I am wrong.

Correct. An EA only runs the start() function when a tick comes in for the chart on which it's loaded.
