It is my understanding that you have to develop your own guidelines. They will be different for each portfolio. If you are daytrading 1 or 2 stocks, you're probably better off with Reg T margining. With a mix of several long and short, you can probably get 6:1 or better. There is no way to tell without experimenting.Quote from risktaker:
I'm trying to come up with some general guidelines. For example, say I have NO positions and $100,000 in an account. Under the Reg T system, I could plan on having a maximum of $400,000 intraday buying power (4x equity). With PM, what should I plan on?
