I am looking to create a custom factor that calculates a "forward 12 month" earnings estimate.
E.g., if the date is 10/1/2018, then i would take the current year (2018) consensus earnings estimate multiplied by ("12/31/2018" - "10/1/2018")/365.25 plus the next year (2019) consensus earnings estimate multiplied by (1 - ("12/31/2018" - "10/1/2018")/365.25) to get my "forward estimate".
I believe I can accomplish this in the backtester with get_datetime(), but I do not believe this is available in the research environment. Any suggestions? Thank you!
