Problem with stop loss

Hi everyone,
I have a question. When I insert a Stop, f.i. Stop = 20 * PIP, MT4 are not 20 PIPs but 30 PIPs. My broker is Activtrades. Does anyone know why?
Thank you

Yes,

The StopFactor is 1.5 by default.
Read about it in the manual:

If you want it to be 20 in this case, just set StopFactor to 1.

thanks Dalla
