New article Testing and Optimization of Expert Advisors has been published:

The article provides a detailed description of the process of testing and optimizing Expert Advisors in the MetaTrader 4 Strategy Tester. The importance of such information and the need for this publication cannot be underestimated. A lot of users who only get started with the MetaTrader 4 trading platform have a very vague idea of what and how needs to be done when working with Expert Advisors. The proposed article gives simple and clear answers to all of these questions and provides a slightly more professional approach to handling these issues using a specific example.

Thanks for this very interesting article.

you say a common reason for "2. Why do the same tests run at the same Dealing Center produce different results?" are the floating spreads. I guess this will have an impact on the simulation and optimisation only if the spread parameter is set to "current", isn't it?

I observed, that even setting the spread setting to a fixed value, e.g. 6, the optimisation results differs from one run to the other. The optimisation is set in the past and all historical data has been fully downloaded in the history center. That is, I am really wondering what could be different when repeating the same optimisation. What could be the reason of that?

Best regards.

I have a question. I am trying to optimize one of my EAs. However, I face a weird issue. More specifically, I get completely different backtesting results each time I run it without any change. So, my questions is: why would backtesting provide different results each time I run it without any change in opitmization parameters, parity, chart or anything else. Any ideas? Thanks..

Hi I like mt4 platform. My suggestion is that Metaqoutes should make strategy tester seperate from the trading platform and add more features like offline chart backtesting. The report of strategy tester should display the profit and loss in pips also. Thanks nice Article.
