主题：加仓代码实现

1.赋值 用“：=” 单用 “=”是无效的。2.sumon和SUMBUY用全局变量方式定义。

INPUT:N(30,5,250,10);
MA30:MA(CLOSE,N);
TR1:MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW));
ATR:MA(TR1,20);
VARIABLE:SUMON:=0,SUMBUY:=0;


IF CROSS(CLOSE,MA30) AND HOLDING=0 THEN
   BEGIN
   BUY(1,1,MARKET);
   DRAWTEXT(1 ,LOW ,"开多" );
   SUMON:=1;
END

IF CLOSE-ENTERPRICE>=0.5*ATR AND SUMON=1 AND SUMBUY<=3 AND HOLDING>0 THEN
   BEGIN
   BUY(1,1,MARKET);
   SUMBUY:=SUMBUY+1;
END


IF CROSS(MA30,CLOSE) and holding>0 THEN BEGIN
   SELL(1,0,MARKET);
   DRAWTEXT(1 ,LOW ,"平多" );
   SUMON:=0;
   SUMBUY:=0;
   end
