Lee I have a spread question for you...

I entered a credit put spread, sold 95p and bought 90p, and had 5 of each so margin was $2500. I let the options expire last friday as worthless. My buying power was decreased by the $2500 margin requirement when I entered the trade, but it has yet to be returned.

This is all in a paper trading account and I'm trying to learn the ins and outs of spreads and selling premium. Is there a time frame for the margin requirement being returned to me to use?
