The Hound of the Baskervilles 当一个可靠的信号没有演变为你期待的行动,价格朝相反方向运动时,The Hound of the Baskervilles的信号形成。 这个信号由来柯南道尔的福尔摩斯探案中的一集。他发现一个重要的线索,谋杀发生时家里的狗没有叫。这表明狗认识罪犯,谋杀是个inside job。缺乏期待的行动这个事实给出了信号。 当市场拒绝响应一个完美的信号,这给你一个The Hound of the Baskervilles信号。这表明有表面之下根本的变化发生了。这是跟进新的有力趋势的时候。
三组主要的指标 * 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不仅受新加入的价格影响,也受被去掉的价格影响,不很平稳。EMA较好些。 选择MA的长度,你想抓的趋势越长,需要的MA长度越长。多数交易者选择10 - 20天。最好不要低于8天因为这与MA的目的违背。 MA的发起人之一Donchian喜欢4/9/18MA交叉的信号,要注意这只适用于强趋势市场。 交易者必须明白EMA象其它工具一样,有好的和坏的一面。MA帮助你识别和跟随趋势,但在盘整阶段会导致两面受损。当EMA走平时,停止使用跟随趋势的工具但继续跟踪这个指标,等待下一次趋势。 MA可作为支撑和阻力。向上的MA作为支撑,向下的MA作为阻力。有些交易者用5天交易量MA来判断市场对趋势的兴趣。
MACD Fast MACD line由短期MA减长期MA形成,slow Signal line是fast MACD line的MA,MACD-Histogram是fast MACD line减slow Signal line。 MACD表达的是市场气氛短期跟长期之间的对比。那么,如同价格穿越MA表明价格上升/下降趋势的改变,fast MACD穿越slow Signal表明了牛熊气氛趋势的改变。虽然MACD-Histogram为正才是牛占上风为负才是熊占上风,但其倾斜方向的改变处已是牛/熊力竭的转折点。对MACD-Histogram来说,倾斜方向比其是正或负更重要。当价格朝一个方向而MACD-Histogram朝另一个方向时,推动价格的力量在耗尽趋势在减弱。 MACD-Histogram在日线图中上下频繁,在周线图中更有意义。MACD-Histogram象车前灯,给交易者一瞥前方的路。 TA最强的信号:MACD-Histogram和价格之间的背离在一年中只发生几次,但是最强的TA信息之一。这些背离指出主要的转折点并给出“超强”的买卖信号。它们并不在每个重要的顶/底,但当出现时,反转的机会很大。
The Directional System (DMI) DMI以每日超出前一日交易范围的累计来判断牛/熊。+DI是所有高出前一日交易范围与两日总交易范围比值的总和,-DI是所有低于前一日交易范围与两日总交易范围比值的总和,DX为+DI与-DI的差和两者的和的比值,ADX为DX的MA。ADX上升时表明市场牛或熊力量增大(取决于+DI/-DI谁在上面)。下降时表明趋势(牛或熊)减弱,此时最好不要用跟势的方法。ADX在+DI和-DI两者下面时表明市场平静,在两者之上时表明市场过热。DMI最好的信号是当ADX在两者之下(时间越长越好),然后上升一定幅度(比如4点)指出了新趋势(牛或熊)的产生。
