Quote from Steve_IB:
SSB is correct. You'll need to create a second login as per the instructions provided above.

Steve,
So if I create a second user for an account, then I can have 2 instances of TWS running the same account on different computers at the same time (1 acct, 2 users, 2 pc's)?

I'll take a shot (I'm not Steve, but I hope I'll do
Yes you're correct you will log into the two instances of TWS with different user ids, but they will both be connected to the same trading account. One user should be able to see orders submitted by the other user (I can't verify this until the market closes as I don't want to risk messing with my automated trading system).
