請教小幫手，下面寫的十日平均振幅哪個地方寫錯了阿

Input: PriceLimit1(10,"股價下限");

Input: PriceLimit2(25,"股價上限");

Input: VolumeLimit1(200,"十日均量下限");

Input: VolumeLimit2(20000,"十日均量上限");

if Close> PriceLimit1 and Close< PriceLimit2 //開盤價大於10小於25

then begin

if Average(Volume,10)> VolumeLimit1 and Average(Volume,10)< VolumeLimit2 //十日均量大於200小於20000

then begin

if Average((High-Low)*100/Close[1],10)> 2

then ret=1;

SetOutputName1("十日均量");

OutputField1(Average(Volume,10));

SetOutputName2("十均振幅");

OutputField2(Average(High-Low/Close[1],10));

end;

選股條件有個:近幾日至少幾日振幅都大於幾%

這類型的腳本要怎麼練習寫比較好呢?

感謝

給你參考

input:w1(0,"幾日振幅")
     ,w2(0,"幾%");

var:i(0),x(0);
x=0;

for i = 0 to w1-1 begin

x += (getField("High","D")[i]-getField("Low","D")[i])/getField("Close","D")[i+1];

end;

x = x/w1;

if x >= w2/100 then ret=1;

感謝幫忙，小弟我想請教關於i=0 to w1-1這個語法，實際上的意涵是從N天前計算到今日or今日回推到N天前啊?

謝謝~~

比如要算5日均振福 w1=5

(getField("High","D")[0]-getField("Low","D")[0])/getField("Close","D")[1]+

(getField("High","D")[1]-getField("Low","D")[1])/getField("Close","D")[2]+

(getField("High","D")[2]-getField("Low","D")[2])/getField("Close","D")[3]+

(getField("High","D")[3]-getField("Low","D")[3])/getField("Close","D")[4]+

(getField("High","D")[4]-getField("Low","D")[4])/getField("Close","D")[5] / 5

等於用迴圈 i=0 to 5-1 這樣OK嗎

這樣寫應該是最簡單

input:w1(0,"幾日振幅")
     ,w2(0,"幾%");

var:x(0);

x = average((getField("High","D")-getField("Low","D"))/getField("Close","D")[1],w1);

if x >= w2/100 then ret=1;
