Hi everyone,
For some days now i cannot figure out how to access historical data in an alpha framework.
I tried to rewrite some example with my own trading mechanism, but I am unable to load historical prices into the update function. Could someone help me figure out what I am doing wrong?
Best regards
Rahul Chowdhury
Hi Korbinian,
You can make history calls anywhere you have access the QCAlgorithm. The Update method in the AlphaModel as the algorithm parameter, which represents the instance of QCAlgorithm which the AlphaModel belongs to. We can make a history call within the Update method using
algorithm.History(symbols, period, resolution)
You can learn more about historical data and alpha models in the documentation.
Best
Rahul
