The problem is in the code.
Hello,
since few days i get to often this erros message, i
think it have to do with the new MT4 build update, does somebody know
why this error does appear now and how to slove it?
i know
that the error mean invalid parameter for a function, but i dont have
change the parameters they have work before also, so this have somethink
to do with new MT4 Update and its not easy to find the reason why this
error comes now.
who knows show the code and maybe another set of eyes will find it
the code is to big, i dont think somebody have the time to look to my complete EA code. But i did think that other people also have ge the same problem since the new MT4 Update and then maybe somebody know exactly why this happen now and how to slove it.
no need the entire code the relevant code only
b.t.w. you'd be surprised what people in this community are willing to do to help others even reading your entire code
I have find now how to slove this problem, it was not enough to look that all parameters for the function have the right type, i have also check if the values from the parameters are not like -1 for OrderSend() and such thinks, Ask price not = 0 and such thinks.
