Quick question regarding history data required for this code:

[[Deleted]]

Hello

Basically I have this code:

 

iOpen(Symbol(),PERIOD_MN1,1);

Which is used in my EA running on a 5 minute chart.

Will I need approx 2 months worth of bars present on the 5 Minute chart, or just approx 2 months worth of bars on the Monthly chart for the code to return the correct figure?

Kind regards

Also does the EA read from the open chart or the history files when calling for a Period() different from the current chart ie, Called PERIOD_MN1 from a 5 min chart

 

Thanks

From history files, you don't need an open chart. For your iOpen() you need the data of the last month on MN1 timeframe.
