I copied the 2013 crash pattern squished to about 1/3 of the time
cut into 5 parts and changed the time of those parts a little bit but tried to keep the price action the same.
Below in green you can see the pattern without being cut, so you can see I didn't change it much.

This picture shows where the trendline is coming from

I wouldn't trade on only this but its something to keep in mind.
