A few days ago I published this idea which is playing out nicely (for the bears, not the bulls)
I think the formation is actually a triple zig-zag, not a double. But either way, the end result is the same. Here's a comparison to what happened in the last bull run in Dec 2017. This bull run, like the last, has been a suckers rally, and we all know what happened afterwards in 2018. Be prepared.
