A friend of mine new to trading looks to open an acct w/ less than 25k but will use 100 sh lots to practice. Now, he's asking about the PDT rules for round trips if your equity is below 25k. I hope you guys can re-enlighten me because its been a while since that PDT thing has had to bother me (thank goodness). If he were to use IB, as I've suggested, using 100 sh lots and does more than the 3 round trips per 4 days w/ total equity of less than 25k, will it be ok? I think he's planning to put in 10-15k, so the transaction sizes will be a lot less than the acct value. 1. Am I correct in assuming he can trade as much as possible since he's on a cash basis anyways? 2. Will he be able to short? I mean, once tagged as a PDT will he still have margin priveleges, thus ability to short? Do i remember correctly or is my understanding inaccurate? Thanks.
