Subject: $30 stack for +EV scanning

Hi {first} — saw your post on {OddsJam thread}.

OddsJam at $99/mo is overpriced for what's basically de-vig math. Built
the same thing as a tool — operator gets the +EV ranked + Quarter-Kelly
sizing.

DIY MIT. Discord/Telegram alerts at $99/mo if you don't want to run it.
