Share New Research 
I am wondering if there is a way to get daily positions for a backtest after it has already finished. I remember Quantopian had a feature where you could save things to a dataframe and it would be available in the backtest output. Is something similar available on QC?

Hi Walter,
We can move data between the backtesting environment and the research environment by using the ObjectStore. The attached backtest demonstrates how we can save the daily holdings to a DataFrame throughout the backtest and save the entire DataFrame to the ObjectStore at the end of the backtest. The attached notebook shows how we can read in the DataFrame from the ObjectStore.
Best,
