I don’t do customer support, so you’d need to contact Robinhood for that information. Every broker is different. Some may give you a warning the first time you break the rule. But if you break the PDT rule a second time, you can probably expect your broker to freeze your account. Again, check with your broker. And always know how many day trades you have left. Know and understand the rules of the game. Don’t let a small mistake blow up your entire account.
