The order request could not be completed: Error no.: 4307

Does anyone know how to fix? I have created some strategies on SQx and I am trying to use them on an MT5 demo account. But what happens is that when the EA has an entry signal, the Thread Title message appears and no trades take place.

When I run the backtest, it works perfectly.

Hi!

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?

Thank you in advance!

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

Thank you in advance

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.
