Well, you got me there. I guess you can call IB and complain to them that they are not following the CBOE guidelines.
Not at all. Your input is valuable and insightful. I guess it's a case that not many retail traders are trading such sizes, and many more would not in any event.
There is no pre-defined pool of option contracts. Both the buyer and seller can be opening the position, therefore increasing OI. You cannot corner the mkt, as it were.
No broker would let you trade 200k options in real life. I don’t think a bank desk would even facilitate it for Warren buffet.
OP, buy 1K ATM GME calls at mkt and report back with the pre and post vol-line on the contract purchased. Thanks.
You read this wrong. No position limited is related to the positions that exist. If you are not in a position, it is moot. No one would ever trade 80 billion standardized contracts with you or goldman or morgan. You have to go into swap market (aka cfd), asked bill huang.
