Hi, guys. I am looking for a broker with API to trade options except IB. 'cuz I am using IB, and thinking of change to another broker. I thought it should be easy, until I found that most of the so called 'direct access trading platform' are designed for STOCK trading, not for OPTIONS. I have checked quite a few brokers with API, none fo them has an API which can send complex options with more than one legs. Does anyone knows or using a broker whose API can submit combo/complex orders? Seems like IB is the only one. I'm thinking maybe I can use basket order do the samething? But I am not sure. If I put buying 30call and selling 35call in same basket order, will that work? Does this same as an bull call spread combo order? Does combo orders routed directly to exchange or routed by broker server until the price meet? Someone said ISE accept combo orders, is this true?
