Here is one chart pattern that usually gives a good profit of at least 100 pips using my trading strategy, the double top which is also a reversal pattern. We can see that once 136.78 was broken we saw some nice momentum in the bears direction and continued going down for a couple of weeks until 129.86. This would have been a good trade to sell and hold.
