darva在renko上的盒子做奇怪的事情

Question

谁能帮助我理解为什么有时此指标在不在图表上绘制买入/出售的情况，而其他时候则在图表上绘制买入/出售，而无需发射买入/出售警报？这是专门针对外汇仪器的Renko传统设置为0.0012。任何输入都将不胜感激。

//@version=5

indicator('Darvas Box Buy Sell', overlay=true)

boxp = input.int(defval=5, title='Length', minval=1, maxval=500)

LL = ta.lowest(low, boxp)
k1 = ta.highest(high, boxp)
k2 = ta.highest(high, boxp - 1)
k3 = ta.highest(high, boxp - 2)

NH = ta.valuewhen(high > k1[1], high, 0)
box1 = k3 < k2
TopBox = ta.valuewhen(ta.barssince(high > k1[1]) == boxp - 2 and box1, NH, 0)
BottomBox = ta.valuewhen(ta.barssince(high > k1[1]) == boxp - 2 and box1, LL, 0)

plot(TopBox, linewidth=2, color=color.new(#4CAF50, 0), title='TBbox')
plot(BottomBox, linewidth=2, color=color.new(#FF0000, 0), title='BBbox')

Buy = ta.crossover(close, TopBox)
Sell = ta.crossunder(close, BottomBox)

alertcondition(Buy, title='Buy Signal', message='Buy')
alertcondition(Sell, title='Sell Signal', message='Sell')

plotshape(Buy, style=shape.labelup, location=location.belowbar, color=color.new(#4CAF50, 0), size=size.tiny, title='Buy Signal', text='Buy', textcolor=color.new(color.black, 0))
plotshape(Sell, style=shape.labeldown, location=location.abovebar, color=color.new(#FF0000, 0), size=size.tiny, title='Sell Signal', text='Sell', textcolor=color.new(color.white, 0))
