backtesting EA

Is it possible to use the expert advisor tester on an EA that uses getobject in reference to objects drawn by an indicator?

If not what are some ways around this?

I guess that would depend on the purpose of the GetObject logic. If it is critical to the proper functioning of the EA, I don't think you can backtest because MT4 can't model the object's values. If it isn't, the code would retrieve a zero or undefined value and continue to run.

You can also try your luck with visual backtesting, in that mode backtester might actually draw the objects and made them available to the EA. Though, maybe you will have to add the indicator to the chart yourself.
