Bill Williams indicators
Fractals (Bill Williams)
Little arrows that mark local tops and bottoms: a high with two lower highs on each side, or a low with two higher lows.
用通俗的话解释
Prices move in swings. Fractals mark the turning points of those swings, giving you natural levels where the market changed its mind, and a breakout above the last up-fractal shows new strength.
计算方法
An up fractal is a candle whose high is higher than the highs of the two candles before and the two after. A down fractal is the mirror image for lows.
Up fractal at candle i: high(i) > high(i±1) and high(i) > high(i±2)
Down fractal: low(i) < low(i±1) and low(i) < low(i±2)如何使用
- Buy stop just above the latest up fractal, sell stop just below the latest down fractal (Williams' breakout entries).
- Use recent fractals as stop-loss levels.
得出结论
- Because two later candles are needed, a fractal appears two candles after the actual high or low.
示例
On a 1-hour chart an up fractal forms at 1.0870. An hour later the price breaks above 1.0871: a breakout entry.

注意事项
- Many small fractals form in quiet markets; higher timeframes give more meaningful ones.
