### Comment:
Contract amount doesn't matter, if you were able to sell an at the money spread for the entire credit you should have sold an infinite number, or as many as the market makers would have let you, so I doubt that happened. However, the credit should be calculated as the amount you sold the short leg for minus the amount you paid for the long leg. If you sold the short leg for .75, and bought the long leg at the same time, I'm guess you paid .50 for it, thus a .5 wide spread with a .25 credit.

### REPLY:
The short sold for .87 and the long I bought for .38. So that’s a .49 credit for a .5 spread. If that’s no free money I don’t know what is. I don’t have a margin account so I can only do cash secured puts
