IB TWS limit of 3 level II/Time and Sales

Nope, just WEX.

 

Thinkorswim shall help in your situation !

 

I do not think TOS can show more than one "Market Depth" window at a time, and it is L1, not L2.

 

I tried it before and it was working.
not sure about the recent versions of the program.

 

TOS will show lots of L2 windows.

 

May I see a screenshot with two L2 Windows.

 

A little, possibly unhelpful, detail from the TWS_API group...

No, it's available to everyone although I think it is only described in the beta release notes and has not made it to the main documentation (at least I couldn't find it).

It is similar to the DOM where you can only have a max of 5 concurrent TickByTick streams. This probably keeps the bandwidth requirements within what they can handle.

FWIW, Nick is a long-time TWS API guy who is solid and knowledgeable.

 

Thank you srinir. I did not know that they offer more than 1 for options, but I expected he was talking about equites not options.

 

They do offer for equities, futures and options. I do not believe they have any restrictions on number of windows or securities.
