Refering to D1 opening price in M15 chart?

[SamSuleymanov]

Need an idea on how I can refer to daily opening price from M15 chart. My EA is attached to M15 chart, is there any way to access D1 opening price info at any time? -> MQL4

1. Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

   Next time, post in the correct place. The moderators will likely move this thread there soon.

2. 1. Perhaps you should read the manual. iOpen Get the D1 shift for the corresponding M15 shift and read it.

   2. 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.

3. Or to avoid having to load the D1. Compute the start of the day, get the shift, and just read it.

   datetime  bod = date(Time[i]);
   int      iBod = iBarShift(_Symbol, _Period, bod);
   double   openD1 = Open[iBod];
