為何 MC 可設定多選項參數?
就是用五至十幾次元去找答案!
舉個極端例子,macd 標準是 12, 26, 9!
若然全部 由 2試到200,backtest回數是天文數字來!
199^6 => 62兆的測試,就算 Genetic 也要近 52萬次檢查
六次元去搵答案
遠非常人可以做的backtest次數,
結果有沒有用,會否啟發你找新出路
是另一個級別的!
另外,就算是線性幾何都好,
若你在 Google 找找 multicharts john ehlers davenewberg
有些已寫了9年的指標(2008產物),例如 leading indicator! 11行裏真正計算得3行!
{Ehlers Leading indicator - coded by dn -from Cybernetic Analysis for Stocks and Futures}
{Apply to the price region of the chart}
Input: Price((H+L)/2), alpha1(.25), alpha2(.33);
Var: Lead(0), NetLead(0), EMA(0);
Lead = 2*Price + (alpha1-2)*Price[1]+(1-alpha1)*Lead[1];
NetLead=alpha2*Lead+(1-alpha2)*NetLead[1];
EMA=.5*Price+.5*EMA[1];
Plot1(NetLead,"Lead",blue);
Plot2(EMA,"EMA");
////This Leading Indicators is smoothed by an EMA to mitigate normal noice gain
////Constants can be adjusted to provide a net lead at low frequencies.
外國大大方方地給你目標價的預測,準不準 肉眼可看完再評分
無奈每支bar都幾乎有摸過,不能直用做autotrade
