Do you use the 200 SMA? few weeks ago I tried a trade idea on the USD/CAD baced on the weekly chart. The idea was a break-up at 1.0 aiming to 1.05. I set the stop loss order at 0.97. The pair did broke up but started sliding sharply. It stopped less than 80 pips from the stop loss order, exactly on the 200 SMA on the daily chart at 0.978, and rest is history (gained 650 pips). That is a powerful indicator that I use almost in any trade idea.
