*According to literature the rising three method  pattern is a five line pattern composed of a
*long candle with white body followed by three  candles with black bodies, followed by a long white candle. The body of three black candles are within the range of
*the first long white candle. The latest long white candle should close above the closing of the first candle. The prior trend should be up trend.
