Hello,
I was wondering if there is an efficient way to get an equity's OBV indicator value from a previous day without having to run the algorithm for a day before it has that data. I'm trying to compare the current OBV value every second to that of the previous day's close, and I'm not sure what the best way to import the previous OBV value would be. Is there a way to do this in QuantConnect without having to wait a day before I can make that comparison? Or is there a good custom data source someone can recommend to do this? Should I just switch it to compare to the OBV value at the start of the algorithm until a day has passed and I can store that value? Any tips would be greatly appreciated.

Hi Matthew Kobrick,
We can use the History method to warm up the indicator using historical data, ready it during the backtest. Alternatively, we can also use the SetWarmUp helper method also. Refer to the following doc for more information. To store the previous indicator values, we recommend using RollingWindow for the task. Refer to the following doc for more information.
Best,
