请教王恺明老师，xaverage函数的最新bar，用high代替close进行计算，我能想到的算法源码如下

xaverage函数的最新bar，用high代替close进行计算，我能想到的算法源码如下，但实际执行过程中barstastus会由2变成1，导致策略不能正常执行，请问如何写才是正确的？如何才能实现xaverage函数最新bar用high来计算？ 望王老师不吝赐教！ Params Numeric Price(10); //数值型序列值 Numeric Length(10); //周期数 Vars Numeric sFcactor; Series<Numeric> XAvgValue; Begin sFcactor = 2 / ( Length + 1 ); if (CurrentBar == 0 ) { XAvgValue = Price; } else if(BarStatus==2) { XAvgValue = XAvgValue[1] + sFcactor * ( high - XAvgValue[1] ) ; } else (BarStatus==1) { XAvgValue = XAvgValue[1] + sFcactor * ( Price - XAvgValue[1] ) ; } Return XAvgValue; End
