I am long in a Futures option on IB. A Globex Put on the British Pound ("6B" series). I am unable to find any instructions on how to excercise this option. It does not appear in the Excercise window under View>>Excercise. On the CME website it says 6B options are American Style, so I assume I should be able to excercise.. Does anyone know the procedure for excercising this option?
