This is a classic problem with spread trading. Since you are trading a derivative of a derivative, the market you are trading often has spikes not seen in the underlying. The market moves overnight also and you can get stopped out if the broker's algorithms calculate your stop was hit, even if the underlying market never traded at that level on that particular day.

It's possible with some SB brokers to buy the SB quote but place stops that are triggered by the underlying market. This might be an option for you to investigate.
