TOS dom shows volume (number of contracts) and goes back 10 levels rather than the default 5 levels of price each way on the NT "SUPERDOM" I only briefly used Jigsaw, thanks for the detailed info, I'll have to reconsider it's worth.
I agree with you about the Ninja DOM; it is worthless. I am by no means saying you should purchase Jigsaw but it is better than TOS (in my opinion). Some of the other products listed in this thread look like they might be even more useful. I am going to test drive them.
