keep in touch with your bank all the time and keep track of your wire 'till it gets there...as soon as thy get it your acct will be funded....ib is at your bank mercy.
Assuming your bank sends before whatever IB's incoming cutoff time is (probly at least 17:00 ET), and you've correctly formatted the FFBO field per the wire instructions, you'll usually see it post to your IB account in TWS within an hour or so of it being sent.
I've routinely had both big and small banks fail to send outbound wires that were submitted before their published cutoff times. It's like the new breed of retail bankers don't understand the urgent nature of wire transfers any more
