I have done bounce plays only the past few days, and for the prior few weeks, I was short.
As I am now focused mostly on the major indices and their proxies, QQQ, SPY, SMH, DIA.
My recent trades were the QQQs was entered last week at 29 and the SMH calls on friday. My indicators were principally the VIX, which behaved similarly to recent bounces and Mcclellen oscillator, which was oversold, as well as a measured move in the SOX. But the market did not accomodate this view and bounce today and I won't wait around much longer.
My longer term view is to get more heavily short after a bounce.
