Options are extremely different than the underlying stock.

Options is everything we discussed except with way less volume and way more margin requirements.

It doesn't seem like IB restricted GME-stock, only options-on-GME-stock, which is a very, very different instrument.

That being said, if I were a paying customer to IB and was hoping for good options-trades during that time, I guess I would have been pissed off. Still though, its a far more understandable issue to have a derivative-trade fall through rather than the underlying stock-trade fall through.

Yes, but the end result was still the same: customers couldn't trade what they wanted to, because the broker couldn't or didn't satisfy their collateral requirements.
