想請問群內高手，想寫出「股價不低於 "過去設定天數內" "特定K棒" 的低點」的選股語法，萬分感謝

input: N(10,"N天內");
setTotalBar(N);
var: myLow(0);
if c=getField("漲停價","D") then condition1=true;
if isLastBar then
    begin
        value1=BarsLast(c=getField("漲停價","D"));
        if condition1=true then 
            begin
                myLow=low[value1];
                if c>myLow then ret=1;
            end
        else return;
    end;
