我用:=计算的指标，怎么会输出指标值呢

主要是看winPrice和lossPrice，怎么会输出指标值呢

代码如下：

VARIABLE:preLow:=0,preHigh:=0,LOPrice:=0,SOPrice:=0,winPrice:=0,lossPrice:=0;

DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);//短周期与长周期的收盘价的指数平滑移动平均值做差。

DEA  : EMA(DIFF,M);//DIFF的M个周期指数平滑移动平均

2*(DIFF-DEA),COLORSTICK;//DIFF减DEA的2倍画柱状线

GOLD:=CROSS(DIFF,DEA);

DIE:=CROSSDOWN(DIFF,DEA);

//commENTARY(BARSLAST(DIE));

IF GOLD=0 THEN

   BEGIN

   preLow:=LLV(L,BARSLAST(DIE));

   //commENTARY(BARSLAST(DIE));

   //commENTARY(preLow);

   SOPrice:=0;

   LOPrice:=(preHigh-preLow)*XX*0.01+preLow;

   END

IF DIE=0 THEN

   BEGIN

   preHigh:=HHV(H,BARSLAST(GOLD));

   //commENTARY(BARSLAST(DIE));

   //commENTARY(preHigh);

   SOPrice:=preHigh-(preHigh-preLow)*XX*0.01;

   LOPrice:=0;

   END

//多头开仓

IF BKVOL=0 && LOPrice>0 && L<=LOPrice && H>=LOPrice THEN

   BEGIN

   winPrice:=(preHigh-preLow)*Win*0.01+LOPrice;

   lossPrice:=LOPrice-(preHigh-preLow)*Loss*0.01;

   BK;

   END

//空头开仓

IF SKVOL=0 && SOPrice>0 && L<=SOPrice && H>=LOPrice THEN

   BEGIN

   winPrice:=SOPrice-(preHigh-preLow)*Win*0.01;

   lossPrice:=SOPrice+(preHigh-preLow)*Loss*0.01;

   SK;

   END

//多头止盈

BKVOL>0 && H>=winPrice,SP;

//空头止盈

SKVOL>0 && L<=winPrice,BP;

运行效果如下：
