iCustom indicator call strange behavior in value result

New comment
 

Hello guys, i am going crazy with a strange issue using iCustom call to have value result from this mq4 indicator https://www.mql5.com/en/code/7376

Code is really simple and it works fine if, for example, in backtest i execute code with a different symbol from where i call iCustom.


I give you an example:

   double mom_eurusd = iCustom("EURUSD", 0, "TSI", 0, 1);
   printf(mom_eurusd);
   double mom_eurgbp = iCustom("EURGBP", 0, "TSI", 0, 1);


If i run this code in backtest from any Symbol, value is right and the same of the chart indicator;   but if i run this code in backtest using EURUSD (so the same pair where i ask value) symbol value is totally wrong (printf give for example 99.99999994458949).



Issue happen with others symbols too.

If i try to get value from symbol that is not running in backtest is all fine but if i want the same value of Symbol of backtest it does not work.


Can sameone help me?

Thanks in advance.

Hello, thank you to move it in the right place.


Anyone find a solution to my issue?

Thanks in advance!

The calling structure for iCustom is: 

double iCustom(

    string symbol, // symbol

    int timeframe, // timeframe

    string name, // path/name of the custom indicator compiled program

    ... // custom indicator input parameters (if necessary)

    int mode, // line index

    int shift // shift

    );

The indicator you call has two inputs

extern int First_R=5;
extern int Second_S=8;


I would try to include them in the iCustom call. I'm not saying I'm going to fix the problem, but it's definitely something I would try.

Also I would use _Symbol instead of "EURUSD"

By the way, you just need to use Print instead of Printf

_Symbol

Hello friend, thanks for reply.

I have change "EURUSD" with _Symbol plus added two input paramters, no way, still with this issue.

Plus i have removed from indicator extern, so they are basically inside parameters without call it in iCustom, still way.


Wait eventually others helps.


Thanks in advance.

 
I tried others way but still in trouble, i am going to be crazy for this issue

I hope this works so that you do not " go crazy" my friend. he he :D

Hello friend, thanks for help but basically was the same code that i try for myself, basically it works like a charm on backtest when i try to get values that is not about current Symbol in backtest, when i put _Symbol or directly string of current pair in backtest i got a totally wrong value.
