Hi, Does anyone have experience with the reqDeepMktData function in the Java API? (I believe many of you do) I use it in order to "listen" to bid/asks prices of certain stock symbols. From my experience, my IB account lets me listen simultaneously only to 3 symbols at a time. Is that the same for everybody? Is there a way to be able to listen to more than 3 symbols simultaneously? Thanks! Dean
I believe you're referring to top market data whereas I'm asking about about market depth. I think I found the solution in the meantime from the IB TWS guidebook: Limitations Given the potentially high amount of data being sent, market depth request's are much more limited. Just as with historical data requests, the amount of active depth requests is related to the amount of market data lines, with a minimum of three and maximum of 60. Number of lines : Max. Requests 0 - 399 : 3 400 - 499 : 4 500 - 599 : 5 600 - 699 : 6 etc... So I think i'm limited to 3 simultaneous deep market requests, unless I buy a few Quote Boosters to take above 400 lines of quotes which will enable me to go from 3 to 4 deep market requests. Can anybody else confirm this is true..? Thanks
Confirmed, that's my understanding as well. Even with giant AUM they don't allow more than 8-10 full books at a time.
