Hello Papercut110,

The error would mean that you are using a value in the collection which is not currently present. Generally you get this when using a BarsAgo like Close[1] when there is not enough data, from your sample this is instead very likely the rows collection being used before its populated.

Where is the print you are adding being placed in OnMarketDepth? You likely need a condition like the following to prevent the error:

 
 if (rows.Count != 0) {     Print(rows[0].Price + " " + rows[0].Volume); }

You are accessing the first row [0] so if there is no first row yet when you try to print this you would get an error.


I look forward to being of further assistance.
