Explanation

Latex code for the Calls and Puts with Different Strikes. For European calls and puts, with strike prices K_{1} and K_{2}, where K_{1} < K_{2}, we know the following.

  • : Call option of strike price K_{1}
  • : Call option of strike price K_{2}

American options, For three different options with strike prices K1 < K2 < K3:

  • : Call option of strike price K_{1}
  • : Call option of strike price K_{2}
