500 maybe? I don't remember.. was late in the day so there wasn't much range left statistically...but there was the fed announcement that afternoon which explained the premium . In a normal day the IC would have been practically worthless at those strikes. The thing is the fed basically just kicked the can down the street but the size got attention I'm sure...they hit both sides lol I don't want to test it but I bet if you bought 1000 call contacts 0 DTE...no matter the technicals, price would move against you. Anybody want to test it? For example I did 10 call option n 0 DTE and targeted .50 and hit it 10 minutes later...$250 all went to plan. I bet if I had sized up to 1000 contracts things would have gone against me or would they let me walk away with 250k? What's the largest 0dte sizing profits here? Mine is 7k with 100 contracts.
I doubt it, but its possible if a lot of traders did the same thing. You would need to go back and do some forensics on the order books in RUT, and /RTY and try to figure out how and why price moved the way it did. Was there a re-balancing of the Russell going on at the same time? Well If so then include all of these stocks in your forensics too. Good luck.
The probability of a 3 SD daily move in the Russell is .135%. If you get one of those, you should be trading that.
%% THAT could work; actually they ''com after'' smaller + mid positions with enough of them LOL But that's also a good thing if one understands business ................................
