Trading : how to deal with crashes (small or big)
You can buy out of the money put options that could minimize your losses (or even make you money)  in the event of a huge crash. Put options are good in that you dont have to worry about not getting filled, or not knowing what price you might get filled with a stop-loss order, however, put options cost money and their value decays over time. It's just like buying insurance, you always have to pay up for it.
