I see that some people hit their stop loss. If that happened then you are out, of course. If you didn't set it then enjoy the ride.
The stop loss isn't supposed to activate on a Flash Crash, but sometimes market watchers will dump it enough just to hit our stop loss and kick us out. I didn't have a stop loss so I get to sell on profit now.
If your stop loss was hit. No big deal, you take the loss and move on. More opportunities will come.
For the rest, prices are climbing, we are going up.
