When you have a debit spread, you are said to have bought the spread, or you are long the spread.
Credits - Credit spreads are the opposite of debit spreads in that you receive more money in premium from one option than you pay for the other. In that case you have sold the spread or you are short the spread.
Using some of the information we learned so far, we can actually calculate the maximum profit or maximum loss for certain spreads. Going back to our example of the vertical bullish spread, the maximum profit would work out to be:
FAK strike price-FAJ strike price-debit, or $55-$50-$1 1/2 = $3 1/2 per contract.
The maximum loss would be equal to the debit which is $1 1/2 per contract. For other spread positions comparable formulas can be used to determine maximum profit and loss.
