轉強天數指標的應用

當我們應用個股儀表板找出個股是否出現買進訊號時，要如何提高預測的精準度呢？  在看過大量的個股儀表板圖形後，我發現，如果股價是長期相對弱勢，但在個股儀表板出現不只一個買進訊號之前，股價就開始抗跌或比大盤強，那麼買進訊號的正確度會提高不少。今天就是來跟大家討論這樣的觀察。

請大家先看這張圖，在這張圖裡我們可以發現，當個股儀表板密集出現買進訊號之前，如果個股雖然在盤整，但其實表現的比大盤強，搭配起來就是一個更精準的買進訊號。

首先，先複習一下個股儀表板的腳本

從這腳本我們可以了解，個股儀表板的目的，在於透過不同的資料欄位，標示出個股可能值得買進的訊號，但這些訊號如果是在多頭末昇段時，也可能會出現，這時候我們可以搭配轉強天數指標來一起看，如果轉強天數指標是從低檔穩定在上昇，就更值得留意。

我自己的轉強天數指標是這麼寫的

複製
1input:period(20);
2value1=GetField("強弱指標","D");
3//個股漲跌幅減加權指數漲跌幅
4value2=GetField("資金流向");
5value3=countif(value1>0 and value2>value2[1],period);
6plot1(value3);
input:period(20);
value1=GetField("強弱指標","D");
//個股漲跌幅減加權指數漲跌幅
value2=GetField("資金流向");
value3=countif(value1>0 and value2>value2[1],period);
plot1(value3);

想法是計算過去一段時間比大盤強且佔大盤成交量比重也比前一天高的天數。

這兩個指標一起搭起來看，可以找到那些埋伏一段時間後開始要發動攻勢的股票

以下是最近很強的股票過去在起漲點時，這兩個指標的搭配情況

以上是我在用個股儀表板時偶然發現的現象 ，野人獻曝一下
