"expert function calls are not allowed" (?)

[kode]

when running my EAs i often get this error message in the experts tab of the terminal:

"expert function calls are not allowed; 'stdlib'-'ErrorDescription'"

followed by "expert stopped"

maybe the problem has something to do with the TrailingStop function trying to modify the order too much...

just wondering if anyone can help me with this

thanks
