I know this subject has been spoken of before here but I can't find the info I'm looking for. Here's how I understand the new SEC rule. Please clarify if I'm mistaken. Accounts under $25,000 which trade more than 4 round trip tickets in any one week will be marked as a "daytrading" account and will no longer be allowed to use margin. (Surely you can trade as often as you like with your own money--right? You just can't use your brokers?) Now here's the part that I'm confused about. If your account is over $25,000 you'll get double margin. Or 4 to 1 versus the current 2 to 1. Is this correct? If so are there any stipulations? What happens if your account dips below $25k and then goes back up? Any info on this subject would be appreciated.
