This Mesa Top offers swing traders a very profitable Clear Air pattern. This double top variation prints after a vertical rise into sideways box congestion. Price then descends all the way back to the rally inception point at the same angle that it rose. Look for the first warning as bars descend off the 2nd high at a mirror image of the rally and slowly gain momentum. Then use a Fibonacci grid to align the Clear Air pockets and predict natural acceleration points. Note how this CMGI pattern presents swing traders with an easy pullback short sale just before the final collapse.
