earnings beat of 189% selloff. On the 4H chart the trend down has reversed
and the ZL MACD is confirmatory. Price has bounced off the lower Bollinger
bands as confirmed by the BB Oscillator. I will take a long trade here targeting
the 0.5 fib level in a retracement of the trend down ( 39.95) with the stop loss
at the pivot low of the Friday morning open. U could easily bounce back up to
its per-earnings trading range in the upcoming week. ( See also PANW)
