I had been very happy with IB future trading and decided to open an account to trade options. However, I discovered multiple issues with the way they handle options and forced to move my account to a competitor. My advice to any new trader who wants to trade options â do not bother with IB they basically sock. For example: - I trade stock index options, which have European expiration stile. One of my strategies is Condor with 2 legs bull and bear. When my friend trades the same strategy with Options Express they correctly recognize that the maximum possible loss on this strategy is equal the spread on either one and therefore the margin is based on a single leg. IB does not!!! It makes a half of my trading capital obsolete. - They recently implemented spread trading and created a lot of hype about the computerized execution. However, me and my friend discovered many times that we create the same limit spread order (his with option express and my with IB) and his order fills in 10 â 20 minutes while mine never gets filled unless I substantially lower my limit price. Couple times my spread order was filled 5 cents below the limit price. - Even if your spread has expired the same day morning and settlement prices are known in the afternoon the margin with the expired contracts still tied up till Saturday morning!!!. It is very important for me to be able to put new position on the same day and again my friend with option express can do that. IB does not give a *&%*(&.!!!
