Quote from peterfigliozzi:
There are two issues: stop or stop-limit; then native and non-native.
The plain stop order is a market order that gets sent when price triggers it. It cannot get "blasted through". You can (rarely) get a lousy price, but at least you get something. To miss your stop entirely you'll have to use a stop-limit order. If you use a stop-limit to exit you carry the additional risk of non-execution. That's why I use a plain stop order to exit.
Entrance is a different story. I used stop-limts for a while but for my style a market order is the way to go.
Native vs. non-native: I would rather have my order sitting in the globex. I don't care that it can be seen, it doesn't make a difference in my trading. However, I will not use the wrong type of order to exit (a stop-limit) just because it is native. If IB's computers go down I can always hedge on the phone with my other broker if I need to. And again, it seems like the major risk is the freaking Globex computers which seem to crash every few months.
