I use etrade (this part edited out at it was factually wrong, etrade did confine gme and amc and my platinum Animal Crossing Items asshole whined ) Disclaimer: I'm not buying GME in any hopes of gain, I simply hate citadel. I can only tell you what I did. About 3 days ago right after RH gave that message they were no more selling'certain stocks', I made an account with Fidelity (took over 5 mins to setup acc + link bank). I then simply did an EFT (electronic funds transfer) and I managed to use 100 percent of this money I transferred immediately even though you do receive any caution linked to funds transferring when you buy the stock right away, however you can still buy it. I'd tell you the specific warning but it already cleared since so I do not recall the wording. I also needed an existing accounts in the old job I had forgot about so when I signed up I just had to upgrade some info. If you set it up and run to a problem I will attempt to assist you as best I can. TD Ameritrade is restricting buying on volatile stocks, but by what I've seen they just increased the margin requirements to 100%. Anybody purchasing a short squeeze on margin would have to be a retard. It is dangerous, and a sensible position for TDA to shoot so that they are not left holding the bag of retards who can't meet a margin call. It also conserves YOLO newbies from themselves, though I doubt that's TDA's motivation. OP left out an important facet. Every day that Melvin can not find the Switches that the parents have already paid , he must pay a forfeit to every parent for their difficulty of waiting for them. And the more pricey these Switches get on the market, the higher the forfeit, since these parents should by rights have these Switches, regardless of how expensive they have gotten. Melvin tries to put off paying the higher market price as long as you can in the hopes that it will eventually return. Eventually the forfeits get so big, Melvin has no cheap Animal Crossing Bells option but to swallow his just desserts and pay market price for the Switches.
