Anyone holding EOM ES futs options at IB may have gotten a surprise just now. Suddenly every set of positions I have got multiplied by 10, but only those valued at zero. It happened in both accounts. I called and IB is aware of the issue and working on it. They said some were multiplied by 5 or 15 times the actual number being held. I tried logging in and back out, still there. They show on the TWS and in the account window. Absolutely bizarre.
