Metatrader 4 stop loss problem!

Hi guys,
I’m facing hard time understand the ST/TP system in MT4

I can’t move my stop loss down! it just goes up and become bigger! check this
when I tried to edit my stop loss order back to 20 pips it grayed out and became inactive

so I had to move to 25 pips so it became active

and some times more than 25 pips so how the “stop loss” system works?

I must b msng something!

I know back when I used mt4 for orders, they had a 5 pip from market minimum. Now it could be anything but they did impose it at one time.

Message your broker, it will be their problem
