Does anyone have the name of someone who could serve as an expert on the following:

1) How sophisticated investors get information on other investors' activities, specifically on the purchase of put options, to guide their own decision making on whether to make similar buys?

2) Whether trading/AI programs flag/recommend buy recommendations based on analysis of that type of increased trading activity on a particular product and also based on publicly-available information?

I need this pretty quickly for a developing situation involving a preliminary injunction.

Emails only please, with credentials and/or experience included if possible.

Thanks,

Alex Eisemann
