Because both risk and reward are quantified at the time of the trade's initiation, one of the most difficult psychological obstacles to successful trend trading—letting profits run—has been eliminated.

Relative Strength Index Extremes with 200-Day Moving Average Filter

Because we are trading the direction of the long-term trend, we can place our exit with profit criteria levels somewhere beyond the mean.
