thats great. i would expect 10 years backtest to take much longer than a measely 3 days.

I have to guesstimate that you're testing on real ticks. If that's the case, then I agree with Michael Charles Schefe's Post #2.

If your EA controls for OHLC prices only, then testing on OHLC data would be more like 3 minutes. I do this routinely with custom charts.

  1. EAs : Don't do per tick what you can do per bar, or on open.
    If you are waiting for a level, don't reevaluate, wait until price reaches it (or a new bar starts, and you recalculate.)
    If you are waiting for an order to close, only look when OrdersTotal has changed. (In MT5 capture the deal out)

  2. Indicators: Code it properly so it only recomputes bar zero (after the initial run).

    Or, reduce Tools → Options (control+O) → Charts → Max bars in chart to something reasonable (like 1K.)
