在研判大盤是否築底時，我常看的是，具指標意義的個股，有多少已有開始築底的跡象，例如股價已符合脫離近期最低點達一成以上之類的條件。
根據這樣的思維，我寫了一個指標股築底指標，這個指標的腳本如下

variable:i(0),count(0);
count=0;
for i=1 to 100 begin
if lead[i]>lowest(lead[i],10)*1.1
//收盤價比近十日低點回升一成
then
count=count+1;
end;
plot1(100-count,"指標股築底家數");
//用100-count 代表數字愈大，愈多股票沒有比十日低點高超過一成
//數字愈小，代表愈來愈多股票比十日低點高出一成
plot2(20);
plot3(35);
這個指標與加權指數的對照圖如下
為了跟加權指數作對照，所以這個指標我是用指標股數量100去減符合築底條件的股票，也就是這個數字愈高，代表愈多股票沒有比十日低點高超過一成，相反的，這指標數字愈小，代表愈多股票築底成功
根據上圖，我們可以看到，這數字在35以上時，代表有三分之一的個股距離近十日低點不到一成，指數在高點，相反的，這數字在20以下時，代表有八成的股票，股價距離十日低點已漲超過一成，如果這個情況出現在指數低點，而且指數下跌，這指標也下跌，代表盤在跌，但築底的家數變多，則是一個反轉的訊號
如下圖
但如果這數字伴著指數反彈後馬上回升，代表符合條件的股票變少，這就不算是築底的訊號，頂多是反彈
這個指標，因為我挑的這100檔指標股裡有上市較短的公司，如果各位希望看更長的數字，就需要讓指標股都上市蠻久的才可以
這點要跟大家作個說明
整理一下，截到目前為止，一共跟大家介紹了續漲股票家數，融資維持率，空方氣勢指標，庫藏股指標
加上今天的這個指標，一共有七個研判大盤落底與否的工具，大盤是否落底，大家可以搭配著這些指標，相互印證及確認，未來在盤勢如果還是詭譎多變，我會繼續跟大家介紹其他我覺得不錯用的工具，也會跟大家從其他面向，分享我研判大盤多空方向的其他類工具。
