Penny Stock MOMO

[haber]

Couple questions, just so I am clear:

Let's say I have 5k in my margin
account, all settled cash.

On Monday I buy 5k of a stock and sell on the same day. That is one DT of three I can use.

On Tuesday I open and close two positions, which uses my remaining two DTs.

On Wednesday , I still have settled cash and I can use it to buy a stock? I sell that stock on Thursday. On Friday, all my cash is settled again?

And, none of this actually has to be done using margin, so there's really no change to my account?

Thanks so much! Sorry for questions ... After reading I think all of the above is right but want to be sure.
