Hi all I have a few questions about vertical credit spreads. I am using Ameritrade and it looks like I can sell a bull put spread in one transaction setting the net credit limit to what I want. I am guessing I can close this same spread by setting the debit limit when I want to close? Also how does the maintenance requirement work for this type of spread. Do I just have to have the cash for the difference between the two strike prices, or do I have to have the cash to buy the stock for the sold puts? Thanks, Droid.
