Pardon my ignorant question, but if the SEC starts cracking down on firms that give more than the allowed 1 to 4 margin as per the PDT rule (like what we are seeing now in the Tuco situation), why would registered firms like Assent, Echo, Bright, etc. be exempt from this? Is there a specific rule that states that registered prop firms are allowed to give their S7 licensed traders more than the standard 1 to 4 leverage? After this Tuco debacle, I would hate to open up an account with another prop firm and have this situation happen all over again. Any input much appreciated. Thanks.
