鱷魚線這個指標是Bill William在1998年所提出來的,這個指標旨在判定趨勢,利用藍線
-顎(jaw)、紅線-齒(teeth)、綠線-唇(lip)及價格的相對位置,分屬不同的意義;並
且在配合碎形fractal後可進一步得到進出訊號。
一、公式:
藍色顎線(jaw)──
1.取Median Price MPt = (Ht + Lt) / 2
2.取 MPt 的13日平滑移動,EMPt = EMPt-1 + 2 / (13+1) * ( MPt - EMPt-1 )
3.取8天前的EMPt值作為當天的顎線值,即 JWt = EMAt-8
紅色齒線(teeth),亦稱Balance Line──
1.取Median Price MPt = (Ht + Lt) / 2
2.取 MPt 的8日平滑移動,EMPt = EMPt-1 + 2 / (8+1) * ( MPt - EMPt-1 )
3.取3天前的EMPt值作為當天的顎線值,即 TWt = EMAt-5
綠色唇線(lip)──
1.取Median Price MPt = (Ht + Lt) / 2
2.取 MPt 的5日平滑移動,EMPt = EMPt-1 + 2 / (5+1) * ( MPt - EMPt-1 )
3.取3天前的EMPt值作為當天的顎線值,即 TWt = EMAt-3
二、說明
在這個指標中,分別計算藍線、紅線及綠線,分別代表著鱷魚的顎、齒及唇。當由下而上
依顎-齒-唇排列時,作者喻為鱷魚自睡眠中醒來,則將開始尋找食物發動攻勢,表示即
將有多頭行情出現;反之,如由下而上依唇-齒-顎排列,則為鱷魚將進入休眠,空頭行
情出現。
並且用突破「有效的碎形」來決定買進或賣出訊號。這裏所指的碎形,是指價格為local
extreme的狀況:指當天的最高價比往前二天及往後二天的最高價還高,這時稱為向上的
碎形;或當天的最低價比往前二天及往後二天的最低價還低,這時稱向下的碎形。
fractal (t) = 1 if Ht > Ht+i 或 Lt < Lt+i , i=1,2,-1,-2
而所謂的「有效的」意思指向上/向下碎形高於/低於紅色齒線,則此時的訊號才為有效訊
號。不過作者Bill William進一步引出無效碎形變有效碎形的觀念,指當原來為無效碎形
,經過幾天紅色齒線不斷下降/上升後,原碎形超過幾天後的紅色齒線時,則原無效碎形
變成有效碎形。注意,採用的碎形應以最新的碎形為準,新碎形出現後,之前的碎形即不
可再用。上漲突破有效的碎形是作多訊號;跌破有效的向下碎形是作空訊號。
這個系統就像我之前所講的
設區間 突破就追
價格才是唯一的考量
其他八啦八啦 不在考慮的範圍內
當你想要掌握的是一個波段 滑價5點10點都只是零頭而已
其他我覺得不錯的還有海龜
你也可以仔細看看混沌交易法 或是碎形
不過自行google囉
或許你這幾個個之前都看過了
但再看一次嘛 溫故而知新
祝大家操作順利囉
