I keep trying to respond but you keep altering your post. Maybe done now?
So you're saying before L2 was available to retail as it is now, one could just call their broker and ask for a rundown of the trade prints and if any orders for 100 or 911 shares had gone through?
I seriously doubt that would have worked or was performed by any trader or any broker, but good story :)
Oh and I will run off now. Thanks for the kind words and have a great day
