What difference between iHigh and High ?

 

does it matter if i use High[0] or iHigh(NULL,0, 0) in EA ?


why iHigh is widely-used way?

 

You can use any symbol or any time frame with iHigh.

  1. Why did you post your EA question in the MT5 Indicators section instead of the MT5 EA section?
  2. MT5 doesn't have a High[] (Predefined Variables - Reference on algorithmic/automated trading language for MetaTrader 5,) only MT4 does (Predefined Variables - MQL4 Reference.)
  3. Why did you post your MT4 question in the Root / MT5 Indicators section instead of the MQL4 section (bottom of the Root page?) General rules and best pratices of the Forum. - General - MQL5 programming forum
  4. No it doesn't matter, why use a (slower and verbose) function call when you can just access the value directly, unless you're planning on moving (eventually) to MT5.
