Quote from RedDuke:
I am not sure about stop limits since I do not use them. I have mine as stop market orders, so it always gets me out sometimes with small slippage. Obviously on days like today you can easily get killed with market orders.
I would guess that if you have stop limit on exchange, and the price trades through it, you might still be in position.
Also some exchanges do not even support stop market, what they do instead is stop limit with very large brackets, so it acts like stop market.
This morning was incredible to watch, and I guess for brave ones to trade.
