Your question is a touch confused. Are you asking about an alternative to stop orders or to market orders?

Stops are overused as a hedging strategy but there aren't really many alternative order types (stop limits are generally less vulnerable but not by much). If you are using stops it should because you've evaluated all your other hedging choices (options, futures, etc) and know they are right even in the face of flashes.

As for market orders the generally better choice is a fill or kill order that crosses the book.
