I'm range trading, if you see my first sell the markets had already established a logical up/down range so I played off that. It then had a huge upside pump and I bought back around where it broke out from and then sold where price was a little congested.
If you flip the chart upside down, I Imagine Luc would have seen the are to the left (my first trades) as a base and would been buying the spike (lower) to exit on a pullback to the breakout point (where I bought).
I've had a few broken base trades, slowly adding it into my trading toolbox.
