When a customer with more than $25,000 is flagged as a PDT, the customer can day trade for unlimited times if he/she has sufficient day-trading buying power(DTBP).
Your day-trading buying power(DTBP) is equal to the excess maintenance margin that is available in your account multiplied by two (or by four, brokers can adjust the leverage). If your Maximal BP is less than your DTBP, when you are initiating new positions, you still need to meet the initial margin requirement.
The "PDT" customer with more than $25,000 still needs to pay close attention to his/her remaining DTBP. If the customer placed trades that exceed his/her remaining day-trading buying power(DTBP) and he/she closes the positions at the same day, the customer will receive a day-trading margin call(DT Call). The customer will have five business days to deposit funds to meet this day-trading margin call, and he/she can withdraw the funds that he/she deposit after the five-day settlement period (closing positions cannot help to meet the DT call). If the customer has one DT Call past due, his/her account will be restricted to liquidation-only status for 90 days.
> Note: All PDTs(pattern-day-traders) need to pay attention to his/her remaining DTBP(If the customer placed trades that exceed his/her DTBP and closed the positions at the same day, the customer will receive a DT call). Customers not marked as a PDT will not receive any DT calls. If a customer was erroneously flagged as a PDT, the customer can apply for removing his/her PDT flag.
