As it's completely BS in my opinion, I never understood that announcement. You never know exactly what the next price will be, in case it moves up 20 pips or 200 and if it goes down 20 or even 200 until it moves up. That means you can be right but being stopped out due to a stop because of market noise.

For me personally it's only important to get a directional bias (daily/weekly) and proceed with this route. Therefor I do not use stops.
