主题：移动止损的写法

全局变量初始止损20个最小变动价位，盈利50mindiff时把 20变为10，开仓后再初始化为20；

VARIABLE:x1=20,y1=20;
if if c-AVGENTERPRICE>=50*mindiff then x1:=10;
if AVGENTERPRICE-c>=50*mindiff then y1:=10;

IF AVGENTERPRICE-C>x1*MINDIFF THEN BEGIN
    SELL(1,HOLDING,THISCLOSE);
END

IF C-AVGENTERPRICE>y1*MINDIFF THEN BEGIN
    SELLSHORT(1,HOLDING,THISCLOSE);
END

if kd then begin
buy();
x1:=20;
end
if kk then begin
buyshort();
y1:=20;
end
