Maybe you can bring sizzle into the equation and look for large changes.

Thats awesome! so can that be translated to look like this? Screenshot here only way I know to add. https://prnt.sc/tsuwg3@axlerod Additionally, here is a screen shot of what my plot looks like. Just realize the graph is just showing how many puts vs how many calls were purchased for a single day and not in any way a short interest indicator. So the big green humps just highlight that for THAT day a bunch of people traded puts relative to calls.
That's basically Peloton right this minute. You can see a ton of people were buying puts around 19-21 May possibly highlighting an upcoming short squeeze. Although, if you go look up the actual short ratio, it was declining significantly at that time. Take it as you will.
