如何使用XS選股腳本判斷現在價格與特定區間的高低點差距??

 

以下設定某價格區間後，抓取區間價格的最高跟最低點，再去跟目前的股價做差距比例計算

input:startday(20161001,"區間開始日"), endday(20161101,"區間結束日");

variable: dayrange(0),valuerange1(0),valuerange2(0);

settotalbar(200);

value3 = getbaroffset(startday);
value4 = getbaroffset(endday);

value5 = value3 - value4;

value1 = highest(close,value3);
value2 = lowest(close,value3);

valuerange1 = (value1 - close) / close;
valuerange2 = (close - value2) / value2;

ret = 1;

outputfield(1,value3,"startday");
outputfield(2,value4,"endday");
outputfield(3,value5,"日期區間");
outputfield(6,valuerange1,"高價比");
outputfield(7,valuerange2,"低價比");

 

以上，提供給大家參考。
