U.S. Dow Topping Pattern or Consolidate Pattern?

U.S. Market Dow Jones show series of patterns, Head & Shoulder, Lower High, Lower Low and Bearish Candle Stick Combination pattern! Support 17000 point is it the last line of defense? Usually before a bear market start it have a topping pattern, at least 6 months to form. If follow up break up trend line and form higher high and higher low, previous pattern become invalid. Hence U.S. market still Bullish.
