The Hound of the Baskervilles 當一個可靠的信號沒有演變為你期待的行動,價格朝相反方向運動時,The Hound of the Baskervilles的信號形成。 這個信號由來柯南道爾的福爾摩斯探案中的一集。他發現一個重要的線索,謀殺發生時家裏的狗沒有叫。這表明狗認識罪犯,謀殺是個inside job。缺乏期待的行動這個事實給出了信號。 當市場拒絕響應一個完美的信號,這給你一個The Hound of the Baskervilles信號。這表明有表麵之下根本的變化發生了。這是跟進新的有力趨勢的時候。
三組主要的指標 * Trend-following indicators: include MA, MACD (moving average convergence-divergence), MACD-Histogram, the Directional System, On-Balance Volume, Accumulation/Distribution, and others. Trend-following indicators are conincident or lagging indicators - they turn after trends reverse. * Oscillators: help identify turning points. They include Stochastic, Rate of Change, Smoothed Rate of Change, Momentum, the Relative Strength Index, Elder-ray, the Force Index, Williams %R, the Commodity Channel Index, and others. Oscillators are leading or coincident indicators and often turn ahead of prices. * Miscellaneous indicators: provide insights into the intensity of bullish or bearish market opinion. They include the New High-New Low Index, the Put-Call Ratio, Bullish Consensus, Commitments of Traders, the Advance/Decline Index, the Traders' Index, and so on. They can be leading or coincident indicators.
Trend-following indicators work best when markets are moving but give bad and dangerous signals when the markets are flat. Oscillators catch turning points in flat markets but give premature and dangerous signals when the markets begin to trend. Miscellaneous indicators provide special insights into mass psychology. The secret of successful trading is to combine several indicators from different groups so that their negative features cancel each other out while their positive features remain undisturbed. This is the aim of the Triple Screen trading system.
MA SMA不僅受新加入的價格影響,也受被去掉的價格影響,不很平穩。EMA較好些。 選擇MA的長度,你想抓的趨勢越長,需要的MA長度越長。多數交易者選擇10 - 20天。最好不要低於8天因為這與MA的目的違背。 MA的發起人之一Donchian喜歡4/9/18MA交叉的信號,要注意這隻適用於強趨勢市場。 交易者必須明白EMA象其它工具一樣,有好的和壞的一麵。MA幫助你識別和跟隨趨勢,但在盤整階段會導致兩麵受損。當EMA走平時,停止使用跟隨趨勢的工具但繼續跟蹤這個指標,等待下一次趨勢。 MA可作為支撐和阻力。向上的MA作為支撐,向下的MA作為阻力。有些交易者用5天交易量MA來判斷市場對趨勢的興趣。
MACD Fast MACD line由短期MA減長期MA形成,slow Signal line是fast MACD line的MA,MACD-Histogram是fast MACD line減slow Signal line。 MACD表達的是市場氣氛短期跟長期之間的對比。那麽,如同價格穿越MA表明價格上升/下降趨勢的改變,fast MACD穿越slow Signal表明了牛熊氣氛趨勢的改變。雖然MACD-Histogram為正才是牛占上風為負才是熊占上風,但其傾斜方向的改變處已是牛/熊力竭的轉折點。對MACD-Histogram來說,傾斜方向比其是正或負更重要。當價格朝一個方向而MACD-Histogram朝另一個方向時,推動價格的力量在耗盡趨勢在減弱。 MACD-Histogram在日線圖中上下頻繁,在周線圖中更有意義。MACD-Histogram象車前燈,給交易者一瞥前方的路。 TA最強的信號:MACD-Histogram和價格之間的背離在一年中隻發生幾次,但是最強的TA信息之一。這些背離指出主要的轉折點並給出“超強”的買賣信號。它們並不在每個重要的頂/底,但當出現時,反轉的機會很大。
The Directional System (DMI) DMI以每日超出前一日交易範圍的累計來判斷牛/熊。+DI是所有高出前一日交易範圍與兩日總交易範圍比值的總和,-DI是所有低於前一日交易範圍與兩日總交易範圍比值的總和,DX為+DI與-DI的差和兩者的和的比值,ADX為DX的MA。ADX上升時表明市場牛或熊力量增大(取決於+DI/-DI誰在上麵)。下降時表明趨勢(牛或熊)減弱,此時最好不要用跟勢的方法。ADX在+DI和-DI兩者下麵時表明市場平靜,在兩者之上時表明市場過熱。DMI最好的信號是當ADX在兩者之下(時間越長越好),然後上升一定幅度(比如4點)指出了新趨勢(牛或熊)的產生。
