如何对连续信号进行编号

Question

我有一个脚本，可以连续绘制许多卖出信号，如果卖出信号之间没有买入信号，我想对它们进行编号，所以第一个信号是p1sell，第二个信号是p2sell等等…如果有买入信号，则计数重新开始。。。。知道怎么解决这个问题吗？

到目前为止，这就是我所拥有的，p1sell是正确的，但其他的不是-

//first sellsignal since buysignal
p1sell=barssince(SellSignal)<barssince(BuySignal) and barssince(SellSignal[1])>barssince(BuySignal)
//second sellsignal since first sellsignal without buysignal
p2sell=barssince(SellSignal)<barssince(BuySignal) and barssince(SellSignal[1])<barssince(BuySignal)
//third sellsignal since second sell signal without buysignal
p3sell=barssince(SellSignal)<barssince(BuySignal) and barssince(SellSignal[1])<barssince(BuySignal)

condA = rising(close, 3)
condB = falling(close, 3)
var countB = 0
countB := condA ? 0 : condB ? countB + 1 : countB
plotchar(condA, "condA", "▲", location.top)
plotchar(condB, "condB", "▼", location.top)
plotchar(countB, "countB", "", location.top)
