This could be happening because you have more than one script/EA trying to perform operations on your account.

Here are some tips to help resolve this issue:

• Install multiple MT4 terminals for the same account and setup fewer charts in each. When there are fewer EAs, it will reduce the chance of them operating at the same time. While installing multiple terminals please remember to change the name of the file in order to enable download. You can download terminals by clicking links below:

  -MT4

  -MT5

• Restart the terminal.
