How to select any number of arrays?

New comment
 

Hi!


When i need to select the close of the third candle away from current price i use: candle[2].close. In this case i need to write the [2], but what if i want to select the close of the last 100 candles? Do i need to select one by one or is there a better way to do that? 


Currently i am doing this, it works great, but if i need to select a large amount of candles at once it is just not doable. 

MqlRates                      rates[];


int OnInit()
   
{

ArraySetAsSeries(rates, true);
return (INIT_SUCCEEDED);

}



void OnTick()

{
 int candleData =  CopyRates(Symbol(), Period(), 0, 3, rates);


     double candle0O = rates[0].open;
     double candle0C = rates[0].close;

     double candle1L = rates[1].low;
     double candle1H = rates[1].high;

}

Why are you writing them all in separate variable? You can use and work with the array.

  1. Your Copy call only returns three. You need to ask for 100.
  2. Or, drop the Copy/array and just read the candle you want. iClose
