Pine script Pine脚本Pivot只是最新的Pivot行

我的密码是蓝色的。但我只想要最新的两行，像棕色的那一行 有什么办法吗

如果有可能，用计数器决定一行或两行

您可以更改要保留的最后行数：

study("Pivot Points Standard", shorttitle="Pivots Std", overlay=true) 

//var higherTF = input("D", type=input.resolution)

higherTF = iff(timeframe.isminutes,iff(timeframe.period == "15", "D", "W"), iff(timeframe.isdaily, "M", "12M"))

prevCloseHTF = security(syminfo.tickerid, higherTF, close[1], lookahead=true)
prevOpenHTF = security(syminfo.tickerid, higherTF, open[1], lookahead=true)
prevHighHTF = security(syminfo.tickerid, higherTF, high[1], lookahead=true)
prevLowHTF = security(syminfo.tickerid, higherTF, low[1], lookahead=true)

pLevel = (prevHighHTF + prevLowHTF + prevCloseHTF) / 3
r1Level = pLevel * 2 - prevLowHTF
s1Level = pLevel * 2 - prevHighHTF

var line r1Line = na
var line pLine = na
var line s1Line = na


if not na(pLine) and line.get_x2(pLine) != bar_index
    line.set_color(pLine,color.green)
