Hey Spike,
Interesting, 3 units of time.
I was taught 1 to 3, 3 to 5 as a measure of time, so I count bars. As a scalper I discovered this concept is more honest on a 10 min chart.
I've also seen it go up to 5 to 7 bars, so it's not 100% accurate. I have a rule - cover on the 5th bar that keeps me out of most significant reversals.
Today's example as I understand bar counting.
