[rajeshks1988 KS]

Hi All,

I am new to MQL, acn any one help me in getting my custom indicator output value in export advisor.

Currently I am getting 0.0 value in export advisor.

Code in custom indicator:-

//---- input parameters

extern int ADXPeriod=28;

//---- buffers

double abc[];



//+------------------------------------------------------------------+

//| Custom indicator initialization function                         |

//+------------------------------------------------------------------+

int init()

  {

//---- 3 additional buffers are used for counting.

   IndicatorBuffers(1);

//---- indicator buffers

   SetIndexBuffer(0,abc);



  



//----

   return(0);

  }



int start(){



   abc[0] = 123.4;

   Comment( abc[0]);



   return(abc[0]);

  }













Code in Export Advisor:-

int OnInit()

  {

//--- create timer

   EventSetTimer(60);

     int i = iCustom (NULL, 0, "TestInd.ex4", 0, 6, 0);

      Alert("Custom :", i);

   return(INIT_SUCCEEDED);

  }

void OnTick()

  {

  }

void OnTimer()

  {

  }

Thanks a lot,

Perhaps you should read the manual, specifically iCustom, and
          Detailed explanation of iCustom - MQL4 programming forum #33 2017.05.23

Your indicator has one input (ADXPeriod) and one buffer.

     int i = iCustom (NULL, 0, "TestInd.ex4", 0, 6, 0);

1. Why are you passing zero as the period?
2. Why are you asking for the seventh buffer (6)?
3. iCustom returns a double. You would know that if you had used strict. Always use strict. Fixing the warnings will save you hours of debugging, but you must understand the differences.
4. It's called an Expert Advisor, not export.
