New article Testing and Optimization of Expert Advisors has been published:
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?
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..
I was looking for this and finally got. Thanks for nice explanation with details.
Thanks & Rgds, Pankaj
I am running a demo version of Metatrader via FXCM on a VPS. I am new to MetaTrader and learning the language slowely. Can I walk myself through this example in Demo mode via a VPS. I am running on Mac with a CorD emulator?
Could anyone explain for me why when I test an EA, every time I test, MT4 just gives me errors for buy/sell orders and nothing happens. This means that no profit no loss happens and the report of equity shows a horizental line!!
Since you did not list the errors, or show the log entries or provided code, we can only guess the nature of the problem.
However, if it gives errors then obviously something is wrong with either the EAs being tested or the history data been corrupted, or maybe ...
We can only guess with the lack of details you provided!
what is the meaning/difference of the 4 coloumns "Value", "Start", "Step" and "Stop" in the Expert properties?
