Hey Community!

I am looking around for a platform where I can backtest some alternative data from a fintech, essentially I want to use buy and sell flags as the signal for when and what to buy within the 14 assets that I have data for. Ideally, I would also want to weight the allocation of available cash when buying based on another metric. I have this data in a CSV file. 

I see different threads about how to upload CSV files but I have not yet understood where or how I write a trading logic that is based on conditional statements (if there is a flag or not for example).

Would really appreciate some feedback from you guys who are more experienced in QuantConnect.

Thank a lot!
