了解为什么 Condition 不断变为 false

Question

我是 Pinescript 新手，正在尝试编写指标。

如果满足以下条件

OPSCond :=  barstate.isconfirmed and close > low[1] and low < low[1] and  close > low 

使变量isOPS为true

isOPS :=  OPSCond ? true : false

分配 OPS 参数，即 OPS 值、OPSIndex（柱索引）和 OPSTime（当 isOPS 为 true 时）

OPS      :=  isOPS   ? low[1]        : nz(OPS[1])
OPSIndex :=  isOPS   ? bar_index[1]  : nz(OPSIndex[1])
OPSTime  :=  isOPS   ? timeline()    : nz(OPSTime[1])

这似乎工作正常，因为线条绘制正确。

为检查条件何时无效而编写的代码似乎也可以正常工作。这里就不重复了。

然而，isOPS 值在每个柱上都显示为 false，即使它应该为 true。请参阅附图。

当图表在 OPS 级别正确显示 OPS 线（绿线）时，我需要脚本将 isOPS 设置为 true，以便可以进一步开发脚本。

我尝试了很多方法，但似乎没有任何效果。我哪里出错了，我能做些什么来纠正它？

示例图表

为了回应 Gustavo 的评论，我添加了 2 张照片来展示我想说的内容。

isOPS = false

isOPS 绘制正确，但其值在表中显示为 false

找到解决方案。修改后的代码如下。

//@version=5
indicator("OPS only",max_bars_back = 500, overlay = true)

//Function region
    
timeline()=>
    txt1 = str.tostring(year(time),"#")
    txt2 = month(time)>9?str.tostring(month(time),"#"):"0"+ str.tostring(month(time),"#")
    txt3 = dayofmonth(time)>9?str.tostring(dayofmonth(time),"#"):"0"+ str.tostring(dayofmonth(time),"#")
    txt4 = str.tostring(hour(time)*100+minute(time),"#")
    timeline1 = txt1 + txt2 + txt3 + txt4
    timeline = math.round(str.tonumber(timeline1))
