Now it should look clearer.

thanks in advance for your help

And please take note that I just created this function to verify if the problem is in using " Points " correctly since I use a 5 digit broker
double dblPoints;

int init()


double GetPoints()                               // declaration of function GetPoints()

  else dblPoints=Point; 
  return(dblPoints); 
}

Justhavingfun: Now it should look clearer.

  1. Play video
    Please edit your post.
    For large amounts of code, attach it.
    EDIT your original post not leave it and add another.

  2. mql4newbie: When I modify my stop loss of an open order, I get this weird Error number 0 with the error description "no error". My result is a FALSE and I cannot understand why.
    You get this when you look at the error number (GetLastError() or _LastError) after a call that successfully completes. Don't look at it unless, e.g. OrderModify returns false.
  3. BarrowBoy: One usual cause is where you OrderModify (for example to move a trailing stop) but actually send unchanged values
    If that was the case you/he would get error 1 OrderModify error 1 during back testing - MQL4 forum

Hi guys


I have created this Function to perform the Trailing Stop feature, it is very helpful

and it can be used on any EA, it works very well

since I copied most of this code from somene else and I am very pleased with it, I just wanted to publish the function I created and maybe help someone else with it too

important notes:

bool Trailing_Stop(int Stop,int Multd)

the function uses just two parameters:

Stop: is the size of the trailing stop in pips, for example Stop=20 pips

Multd: factor to be used in case your broker is a 5 digit broker instead of a 4 digit broker. If this is the case Multd=10. If you use a 4 digit broker use Multd=1.

Don't modify the order if nothing needs to change.
