Topic: ON /OFF complete EA in MT4 depending on indicator set level

Hello there
can anybody tell me how to stop the EA from trading on all c-pairs once the indicator for standarddeviation in FST set to  20, 0.0011, simple  exeeds the set level of  eg. 0.0011. The FST should not stop the corresponding currencypair only but the whole EA which corresponds to the button in the menuebar of MT4
So all other currencies will also stop then.
Is it possible to realize this and if yes i wonder how.

thanks for reply and help
best regards
