Scalp Trader Daytrading Technical Debate Question!?

Daytrading Technical Debate Question!? - scalp trader

My colleague wants a manager and explained his strategy to protect the scalp and plans to open an account with $ 25,000 by the operator as a model clearly SEC rule. In addition, your account is on a margin account.
He explained that if the trade whenever you want to use the total amount of $ 25,000 per transaction, so that you maximize profits assuming that the success of operations. (I know it's stupid and dangerous, and said that he still loves to take risks.) It is hoped that this strategy is the right buy / sell, buy / sell, buy / sell .... as often as you can during the day.
Now my question is, suppose your first transaction was a success, we should not expect T 3 days before the capitalization of $ 25,000 in your company, then on that day? If this is not against the rules of the SEC as a "breach of good faith" or "free riders"? Since the trade does not really solve that 3 days?
