After buying and selling a stock in less than 30 minutes, l wanted to buy another stock with the same money. But the broker said I am only allowed to reinvest my money every 3 days after selling it.

Anyway around this? l just wanna use my own money to purchase/sell and repurchase and sell on the same day with the same money.

this is a new one on me -- maybe its because l always had a lot of cash in my account but l never had this problem -- l would question his authority!!!
