La demande de commande n'a pas pu être complétée : Numéro d'erreur : 4307

Quelqu'un sait-il comment résoudre ce problème ? J'ai créé quelques stratégies sur SQx et j'essaie de les utiliser sur un compte de démonstration MT5. Mais ce qui se passe, c'est que lorsque l'EA a un signal d'entrée, le message Thread Title apparaît et aucune transaction n'a lieu.

Lorsque j'exécute le backtest, il fonctionne parfaitement.

Bonjour !

I’m having these problem with strategies generated with v137 on different strategies and symbols.

Is there any working solution rather than upgrading to a new version?

Could you please confirm from which version on the problem has been solved?

Merci d'avance !

Please share the strategy and MT broker you use, we could test this

Thank you very much, Thomas, for your answer.

In my case, the solution was quite weird: I forgot to activate the Automated Trading, and the error was so unspecific I couldn’t find out where the problem was after a couple of weeks.

So, nothing related to SQX!

Julian Santos,

1/ Which money managment do you use ?

2/ Which broker do you use ?

3/ would you please attached your Metatrader log ?

You can as well send your MT log and info to support directly.

This would be a great help, if you bring these elements

Merci d'avance

Please, check the MT log, you may have the error in the previous line

if you look at the attached screen capture, you will see an invalid volume error in the ‘failed market buy line’

In this case, the instrument J225, have a step 0.1.

A size lots of 1.39 is incorrect, it should have 1.4.

the 4307 error can appear if there is not enough margin, or if the entry is outside of the trading session as well.
