Thanks @Ringandpinion. I do have TOS as one of my accounts (have been using it for paper trading recently). I see what you mean about getting the scan parameters to keep the desired timeframe but I was able to get it working after a little trial and error.
Do you know if there is a way to sort the results by earnings release date? I looked around in the settings and couldn't seem to find anything, maybe I'm just missing something?
