That I can only tell you exactly what I did. About 3 days back after RH gave that message they were no more selling'particular stocks', I made an account with Fidelity (took over 5 mins to setup acc + connection lender ). Then I simply did an EFT (electronic funds transfer) and that I was able to use 100% of the money I transferred instantly even though you do get any warning linked to funds transferring when you get the stock straight away, however you can still purchase it. I would tell you the specific warning but it already cleared since so that I do not recall the wording. I also needed an present account in the old job I had forgot about so when I signed up I simply had to update some info. If you set it up and run to a problem I will attempt to help you as best I could.
TD Ameritrade is restricting buying on volatile stocks, however from what I've seen they only increased the margin requirements to 100%. Anyone purchasing a brief squeeze margin would need to be a retard. It's dangerous, and a sensible position for TDA to take so that they are not left holding the bag of retards who can't meet a margin call. Additionally, it conserves YOLO newbies out of themselves, though I doubt that is TDA's motivation.
OP left out an important facet. Every day which Melvin can't get hold of the Switches the parents have paid for, he has to pay a forfeit to every parent for their trouble of waiting for them. And the more expensive these Switches get on the market, the greater the sacrifice, since these parents should rights already have these Switches, irrespective 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 become so big, Melvin has no choice but to swallow his just desserts and just pay market price for those Switches.
At least that's the way my retarded brain translated it, but I am only a dumb ape, do not listen . I'm just holding GME since I believe in the firm! ??????
