This is a breakout pattern that everyone and their dog will be able to see. Therefore it will be loaded with buy orders on the high-side. These buy orders will get filled, and the market will now be saturated with those same traders sell orders.
This may lead to a reeeeally sharp downturn.....the double-false break, or a break to the low-side is what you really want.
There's your chance for a second entry!
