How to find Second M15th Candle Open price of the day

[Bala ji]

Guys, Need help with syntax.

I need to find Second Candle of the day's Open Price. 

The code below works for first half an hour of the day, then it does not produce the result i want because of "0"(Current Candle). Kindly guide me with the right syntax. 

if (iOpen(Symbol(),PERIOD_D1,0) == iOpen(Symbol(),PERIOD_M15, 0))

  {
   //"display symbol"
  }

 What is the syntax to find the Open or high or low of the user desired n th candle of the day. Thank you in advance guys.

What is the syntax to find the Open or high or low of the user desired x th candle of the day.

1. No it doesn't; only for the first 15 minutes. After that you have a new M15 open.

2. Doubles are rarely equal. Understand the links in:

3. On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

   On MT5: Unless the chart is that specific pair/TF, you must synchronize the terminal Data from the Server.

4. Find the index of the first of the day candle and subtract x.

   datetime today = date();
   int      iM15  = iBarShift(_Symbol, PERIOD_M15, today);
   double   open_m15_first  = iOpen(Symbol(),PERIOD_M15, iM15),
            open_m15_second = iOpen(Symbol(),PERIOD_M15, iM15-1),

5. Do you really mean the M15 (irregardless of the chart,) or do you mean the current chart's TF? (PERIOD_CURRENT)
6. Do you understand that unless your broker uses NY+7 timezone, what you are looking at is meanningless for forex.

I dont know how exactly but you can do smth with iBarShift()
