double sellpoints()
{if (fmod(Bid,0.500)==0 && Bid>a)

{return (1);}else return (0);}

i have this function.but the problem is that i cant set it to fmod(Bid,0.200).my ea doesnt do any action while it s working in 0.500 or 1.000.what is wrong with that fmod function.


 

Devastater:

   double sellpoints()
   {if (fmod(Bid,0.500)==0 && Bid>a)

   {return (1);}else return (0);}

i have this function.but the problem is that i cant set it to fmod(Bid,0.200).

  1. When you post code please use the SRC button! Please edit your post.

  2. Don't use int (or worse double) when you mean bool. Simplify your code. Why this always returns false? - MQL4 and MetaTrader 4 - MQL4 programming forum
    bool sellpoints(){ return fmod(Bid,0.500)==0 && Bid>a; }

  4. Floating point has infinite number of decimals, it's your not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)

  6. Decide how close price has to be. Exactly, try:
    bool sellpoints(){ return MathAbs(Bid - MathRound(Bid,0.500) ) < _Point && Bid>a); }

  7. Hard coding constants (0.500) means your code breaks on other symbols. If you mean 50 pips on JPY pair, code it that way (Link № 6.) If you mean 5 ticks, code it that way.
 

I m new here,also in programming and trading.i have some ideas and trying to make my own ea.its hard to solve problems with books.thank you 4 your help.
