I'm a programmer looking to learn more about finance (aka zero experience in trading). I've been digging around for a while and haven't been able to find a good answer for this one sorry if I missed a previous post. When creating my pipeline, what should I filter to ensure that I only return stocks that are tradeable in Robinhood? My algorithm is giving me amazing results on backtesting but when I run live in Robinhood it is less than impressive. When I dig into some of the logs there's a lot of rejected orders due to stocks that aren't tradeable in Robinhood. I was thinking about checking orders each day and tracking those that are rejected, but I'm hoping that there is a better way to build a pipeline. Thanks in advance!
