Re: C++ TWS API reqMktDepth() giving 309 error


 

No problem here. Just tried NQZ4 as the third subscription through a paper account that already had two active reqMktDepth subscriptions for other instruments. Worked as expected.

Any chance you are indeed requesting market depth subscriptions for more than three different instruments simultaneously? Keep in mind that TWS L2 tools count against the three subscription limit, in case you use those.

Anyone else experiencing this? Same error code / thing happening in a python dummy script I put together as well for reqMktDepth() w/ ib_insync() api. My subscriptions all seem to be in tact too...
