Many people using Interactive Brokers don't seem to know that you can use Native simulated market stop orders on Globex with Interactive Brokers. They do have their own simulated market orders which reside on their (IB) servers, but this isn't ideal if they happen to go down, and they are slower (sometimes a lot) than the native market stops. All you have to do to place a native market order stop is use their Stop limit order and set the election price at say 890 on the ES for example, and the limit at 893 (for a buy stop). This effectively creates a market order with 3 points of leeway once the election price of 890 is hit. 99% of the time you will get 890, but if the market is moving fast, you will get the next best price. Globex will even give you 899.50 if it becomes available first (rare but it happens). It doesn't make sense to have IB do the same exact thing for you and create one extra step in the execution process. And it doesn't make sense to risk IB being offline for some reason and be unprotected in the market.
