Open, high, Low, Close [] double

New comment

Hi

The double open[] gives the open price of a bar. As in https://docs.mql4.com/predefined/open

Is that price bid or ask?

Thanks

Series array elements are indexed in the reverse order, i.e., from the last one to the first one. The current bar which is the last in the array is indexed as 0. The oldest bar, the first in the chart, is indexed as Bars-1.

  1. In MT4, the predefined array is Open[]. open[] is a parameter in OnCalculate. The former is an asSeries array. The latter, you must set the order.
