This last weekend the option symbol transition coordinated by The Options Clearing Corporation completed, with the last set of symbols, starting with underlying symbols of S through Z, switched over to the new system. In almost all cases the 3 to 5 letter underlying symbol now works as the option identifier. I think the new system is a real improvement. I wish all the brokers had implemented it the some way, but I guess that would be too much to ask. Click here to see the Schwab, Fidelity, and the generic approaches.
