Thanks guys - I did infact solve this precisely as you suggested.

I'm having trouble getting this to work with Pandas but works fine with GenericCSVData.

More information is here:
https://www.backtrader.com/docu/extending-a-datafeed.html

I have a Pandas dataframe which contains my Open, High, Low, Close, Volume columns at minutely resolution. I will load this custom data-set into Backtrader. In addition, I have my own indicators/signals pre-calculated for every minutely time-step.

Having already skimmed the Platform Concepts (https://www.backtrader.com/docu/concepts.html) in the documentation, I haven't been able to see how best to load my own pre-calculated signals.

Please could someone point me to the correct place in the documentation, or share a code snippet? Sorry if this is a duplicate topic, happy to be pointed to the best original topic also.

Thank you very much in advance.
