I see what you're saying - sorry, I trade the pit contract. But my experience with the electronics (which is why I don't trade it) is that they will fluctuate with wide variances from the pit when things move like they did this afternoon. Stops get run over in the electronic with no control. That actually is the argument the pits use to justify their existence. The only protection you can attempt to use are Stop Limit orders, but you risk not being filled in a meltdown. I see you've been around awhile so you probably already know all this.
