Lucy L 2 Posted June 17, 2019 (edited) Hi guys, Just joined the community for a try out (started day trading 2 months ago). Always wanted to be part of the BBT the community cause I got so many things to learn (and so many questions)! I'm currently using Mac TWS and also trying on DAS on Parallel (before I make the decision to commit fully to PC and DAS). I have noticed the Level 2 sizes data on Das is at most times smaller than the data on IB. Screenshots attached (top DAS, bottom IB). I have contacted DAS's support and their reply is DAS 's L2 is "different". After insisting for more info they came back with an answer: DAS doesn't have some books such as BATS... This is news to me and I'm wondering if it's true. And if so, how much impact could it affect trading results?

BBT Member 001 27 Posted June 17, 2019 Level 2 is really an alias to order book for different exchanges> In DAS you will get NYSE and NSDAQ but you have to ask for them to add ARCA. I think AMEX, BX and BATS are not there, not 100% sure. Share this post Link to post Share on other sites

Great question, i assume they include more orders so it is better but das has the most important On 6/17/2019 at 9:22 PM, Lucy L said: So is Lv2 still 100% meaningful without AMEX, BX and BATS.. ?
