What does this code do?

Hi - I'm wondering what does the code in the screenshot do? I have 2 more additonal data series. It's generated by the builder. I'm not sure if they need to be changed or not.

Thank you!

Hello HiddenPhilosopher,

This code will prevent the code from continuing if the primary series is not processing if there are multiple series added to a script, and will prevent the code from continuing if the first series (the primary series BarsInProgress 0) or the third series (BarsInProgress 2) do not have at least one bar to process in OnBarUpdate().

My primary series is 1 minute, and I added 30 minute additional data series. My strategy uses 200 EMA on 30 minute bar data. Apparently, to calculate 200 EMA, it needs to have 200 30 minute historical bars when strategy is started. How should I set properly to make it work? Please help me understand it. Thank you!

Hello HiddenPhilosopher,

Are you having an error that you need assistance with?

What is not working properly?

Are you supplying the BarsArray[BarsInProgress index] as the input series to an indicator?

Are there 3 series in the script or just 2?
