Great question Mr. ES . Usually I use limit orders for both entries and exits, but when the market seems to be moving quickly, I use market orders, especially for exits. I have seen $15 MNQ profits disappear in mere seconds before. I would rather get $10 on that trade than -$10!
I would strongly suggest you use only stop markets on your protections...stop limits can be blown through, as you said, in the blink of an eye.
Limits on entries? Mreh. I find them to be of limited value, as even those can be broken on fast moves, so you never get in. 6 of one, half-dozen of the other.
