Disable the EA from the chart



I have an EA and I don't have the source code and I cannot modify it

I activate it for multiple pairs and when he open a trade in one of the pairs  I want to close the EA of the other pairs and only hold it in the pair the order was opened in
You probably need to request the creator of the EA for such a button that will allow you to disable that instance of EA via chart. 

Otherwise of you want to remove the EA from chart itself instead of disabling it, you can remove it fby right clicking the chart and selecting expert advisor from the context menu, selecting the EA and deleting it from chart.
