@jstap @ambrogio Thank you very much, problem solved!

@ambrogio Thank you for you answer but I tried ´int´. Then the + sign won't appair and the EA won't even open trades at all.

With the function 'Adjust' it is possible to tweak a certain value. When I use text: '+5 pips' it is working fine. Now I want to use a Constant in stead of the text. I made a string constant with the value'+5 pips' but this time the EA does not add 5 pips to the original value. What am I doing wrong here?
