What country? And yes, you need $25,000 or more at all times for DT for an equity account for ALL US registered Broker Dealers. I generally recommend $30,000 or more if you can do that.
SoRRY i just one more question. I understand that the PTD rule allows unlimited trading one day. So if for a beginner like me this would be a terrible idea. What im asking is, if I do open an account, of lest say 500 usd which limits me to only three trades per week; does that include buying and selling or reversed in the case of shorting? And also is there a restriction on the amount of shares i can purchase?
