Calculate the daily difference between highest price and lowest price, how to?

[nicolasxu]

I have a simple task: Calculate the daily difference between highest price and lowest difference and print the result in the console.

 

 

So far I can only successfully do:

void OnTick()
  {
//---
   SymbolInfoTick("EURUSD", tickInfo);
   Print(tickInfo.last);
  }

Can anybody give a sample code for this simple task?

Thanks!

you need to loop for the number of days you need else just copy the daily rates and do a high minus low

or even atr can suit

Thanks a lot for helping. How do I copy the daily rates? 

Use SymbolInfoTick?

you can use periods of one day and substract the high with the low. Or search the market to use already coded indicator/script.

 void OnTick()

  {

//---

   Print("The Period() returns: " + Period());

  }

Above are my code. The value Period() returns is always 16385, no matter how I set the period of the chart.

I set the chart period by clicking right button on chart, e.g.: EURUSD, and then select Periodicity-> M1.

No matter how I set the Periodicity, M1, Daily, Weekly. Period() always returns 16385. I am using test data. 

What did I do wrong?  Should I expect Period() to change if I change Periodicity?

 Is this what you want?

//+---------------------------------------  iHIGH ---------------------------+
double iHigh(string simb, ENUM_TIMEFRAMES marcoTmp, int nVela= 0)
  {
   double array[1]= {0};
   int nCopiado= CopyHigh(simb, marcoTmp, nVela, 1, array);
   return(array[0]);       //si el valor devuelto es cero, falló la función
  }

//+------------------------------------------- iLOW -----------------------+

double iLow(string simb, ENUM_TIMEFRAMES marcoTmp, int nVela= 0)
  {
   double array[1]= {0};
   int nCopiado= CopyLow(simb, marcoTmp, nVela, 1, array);
   return(array[0]);       //si el valor devuelto es cero, falló la función
  }

//...
double difPrecio= iHigh(simb, PERIOD_D1, 0) - iLow(simb, PERIOD_D1, 0);
Print(DoubleToString(difPrecio));
//...
