What are the differences between the three modes of testing in MetaTrader 5, and what should be particularly looked for? How does the testing of an EA, trading simultaneously on multiple instruments, take place? When and how are the indicator values calculated during testing, and how are the events handled? How to synchronize the bars from different instruments during testing in an "open prices only" mode? This article aims to provide answers to these and many other questions.

When you test in the Strategy Tester, is your "Modelling", "Every tick" or "Every tick based on real ticks"?

What do you mean by the "broker data" and "tick data"?

The real tick data is provided by the broker alongside the OHLC bar data.

Are you using a different source of tick data?

Don't test against different tick data if your intention is to compare it to real live trading on your broker.

Forex, CFDs, etc. are not centralised exchanges and data is different between brokers.

If you want to compare your live trading with your back-tests, then use your broker's historical tick data for the tests, not 3rd party data.

Thank you sir.
