谢谢老师！继续请问一下，我要实现只有出现买入信号后，才标注卖出信号；而且买和卖是一对一的组合关系。即出现一个买，后面只能出现一个卖；当下一次出现买后才能出现卖。这个麻烦帮忙写一下。

下面是卖的代码

  begin
            DRAWTEXT( CON1 OR CON2 OR CON3 OR CON4 OR CON5 OR CON6  OR CON8 OR CON9 OR CON10 OR CON11 OR CON12  OR CON13 OR CON14 OR CON15  OR CON16 OR CON17 OR CON18 OR CON19 OR CON20 OR CON21 OR CON22 OR CON23, LowPrice, '卖', COLORBLUE); // 在当前K线的低价位置标注“卖”
        end;

参考如下代码结构呢：
VARIABLE:买=0,卖=1;

BUYSIGNAL:=CON100 AND CON101 AND CON102 AND CON103 AND CON104 AND CON105 AND CON106 AND CON107 AND CON108 AND CON109 AND CON110 AND CON111;  //买入信号条件
SELLSIGNAL:=CON1 OR CON2 OR CON3 OR CON4 OR CON5 OR CON6  OR CON8 OR CON9 OR CON10 OR CON11 OR CON12  OR CON13 OR CON14 OR CON15  OR CON16 OR CON17 OR CON18 OR CON19 OR CON20 OR CON21 OR CON22 OR CON23;  //卖出信号条件

IF BUYSIGNAL AND 买=0 AND 卖=1 THEN BEGIN
   DRAWTEXT(1,L,'买');
   买:=1;
   卖:=0;
   END

IF SELLSIGNAL AND 买=1 AND 卖=0 THEN BEGIN
   DRAWTEXT(1,L,'卖');
   买:=0;
   卖:=1;
   END
