I would ignore the Jigsaw tools and similar improvements to what is an awful DOM, "SuperDom" and just switch to Thinkorswim's DOM, it's far superior and free for account holders, although the data is slower.
TOS DOM is "far superior" to Jigsaw trading's DOM? I know for a fact you have not even tried Jigsaw's DOM. If you had you would not be making a statement like that. (BTW- I have a TOS account and got started with futures using their tools. I have used their DOM) Just this morning was a great example of Jigsaw's DOM usefulness. I was watching the Sept 6E contract around 4:50am (cst) and a limit seller had an iceberg order in. He sold over 2000 contracts into heavy market buy orders. You would have thought the buyers would have given up after seeing the first thousand lots swallowed up. This guy held the market below this price for over a half an hour. You will not see this clearly on the TOS DOM.
I haven't tried Quant chart myself so maybe you're right. Since you are experienced with Quant chart I have a couple of questions. 1) Is it easy to see when limit orders are pulled and added to the DOM ? This is one of the things I look at closely. 2) Iceberg orders. Does it show when someone keeps refreshing a limit order? 3) Does it keep a running tally of trades at each level? This is a pretty handy feature Jigsaw has; I can see what hit the offer and what hit the bid at each price level. I see they offer a free trial. I am going to sign up and check it out.
1) Yes. You can see all limit orders movement: add, remove, replace, algorithmic limit orders and others. 2) Yes. If you see a market order after which the limit remains 0 and then instantly adds new limit orders, be sure it is an iceberg. It is very easy to see if you can observe for a while. 3) You can see absolutely all activity that takes place in the Level2
It's already obsolete technology of order flow analysis. 9G Trading DOM - a large number of digits and nothing else.
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.
