I trade the OEX through Schwab's Sreet Smart. Commissions are high, but I have real time charting, real time data etc. I love having the OEX chain updating in real time. They also have conditional orders, but I haven't tried that with options (only tried it with stocks). What ever you do, don't use marekt orders on OEX options - the spreads can be large and limit orders are a must.
