So TSLA of course exploded today with inclusion in S&P, I had been getting 420 calls in the 400 region over past 10 days but sold off during day for basically even. I realize it's a crapshoot guessing when news will or wont come out, but theres plenty of smart money and insider traders that precipitate these events with options flow. Does anyone use a service like flowalgo or cheddarflow or wallstjesus that helps decipher in this regard? Or pick out unusual activity?
