What are all the things that automatic validation checks?
- www.mql5.com
- no trading operations
- Any questions from newcomers on MQL4 and MQL5, help and discussion on algorithms and codes
- I get an error in the automatic market validation. The error message is "strategy tester report not found.
have you made the necessary calls to,
TerminalInfoInteger MQLInfoInteger AccountInfoInteger AccountInfoDouble SymbolInfoInteger SymbolInfoSessionTrade OrderCheck Functions and their params ?

There can be mnore, or less, but this is what i usually check as a base stamp before trying to open a position.

I have these function for checking inputs
//----------check user input--------------- // return 1 if error is found void CheckUserInput() { if(TakeProfit<0 || StopLoss<0) { Alert("EA stopped: Check your settings. SL and TP cant have a negative value."); //Reset=1; return(1); } if(RiskPercentage<=0 && Lots<=0) { Alert("EA stopped: Check your settings.

Automatic validation is the problem. Because before they removed the moderator tab Ive never had problems with automatic validation. Perhaps there are latest changes that cause this.
Well why didn't you say it was MQL4 ?
I don't use that anymore.
And it looks like your missing out on a lot of checks right there, not just one.
If trading is not allowed for whatever reason, and your EA will still try to send an order, there will be an error.
These checks are good because they will filter out the trash EA's from the decent ones.

Thanks for your reply. Yes its for mt4. Many still use mt4 the most popular platform. The automatic validation returns the "no trades opened error" only that one error. Started happening only after latest changes in the submission page.

I m troubling with automatic validation too. While backtesting my ea with mt4 strategy tester, no errors found in the Journal. The same ea, on automatic validation , makes a test from 6 4 2016 to 27 5 2016 founding 10 errors. All of them are ordersend error 131 - invalid trade volume - tried to place the Normalize Volume function before Start() and then , placed at the bottom of code. Both can t fix It!!!! Helppp
I don't know that function.
Start() in an EA nowadays?
