Hi miklosh,

Here's what I remember:

A = American
C = Chicago
P = Pacific
X = Philadelphia

Often more than one exchange makes a market in a particular stock's options. I often check the CBOE before buying or selling an option to see if there is a disparity in the prices offered. When there is, I often call my broker (Schwab) and ask them to route my order to the exchange with the best price.

Best regards, John.
