Hi Lachiner - I'm on Interactive Brokers so I'm not familiar with ZF's setup.
For my data to show up, I need to launch IB's Trader Workstation (which also launches OwnData) THEN TS 8.7 in offline.

The Trader Workstation needs to accept the incoming API connection from OwnData, otherwise I get similar sort of error message.

If you're getting a symbol list by just entering the root "ES" then it sounds like its connecting fine....

Has anyone been able to use Owndata 2.7 on win7 64bit and connect to Tradestation 8.6 correctly?
My Ts8.6 does not recognize Owndata running in the background thus symbols are not recongnized although Owndata does refresh symbols . I think the issue is with competability to Win7 64 but I am not sure.

I'm having the same problem trying to connect between TS 8.7 + owndata 2.7.
my feed source is barcharts.com.
owndata can and connecting barcharts feed but can't transfer data from
it directly to TS 8.7.
hope someone here would help.
thanks.
