How to know when multi timeframes are all loaded?

[wjadevries]

I'm adding an extra data serie in the onstatechanched event (State==atatse.Configured or DataLoaded).
The data series are all for the same instrument, but with different timeframes.
The main (chart) data serie is M5, and the extra dataserie is D1.
How can I determine when both data series are completely loaded, so that I can use Closes[1][1] without errors?
I also need to get the ATR(Inputs[1], 14).Value[1] but get errors about "accessing a barsAgo for a bar that is not loaded yet".

Please advice.

Hello wjadevries, thanks for writing in.

To check that you have at least 1 bar in both series, you can add this check at the beginning of OnBarUpdate:

if(CurrentBars[0] < 1 || CurrentBars[1] < 1)
{
return;
}

//access Closes[1][1] here, CurrentBars Documentation

The ATR problem could also likely be fixed by adding this CurrentBars check at the top of OnBarUpdate.

Please let me know if I can assist any further.
