Pinescript V2到V4转换，不能与自引用变量转换

Question

我正在尝试将我的pine脚本版本2指示器转换为版本4，因此我发布了它，但是它使用了一个自我引用变量，它们在版本3中删除了它。要求解它页面我将在底部链接，但我无法弄清楚如何正确包装它。如果有人可以帮助我包装这个公式，将不胜感激。先感谢您。

这是代码。自我引用变量在第33行（BSSUM）上，并将第9行作为其公式的一部分。

interval = security(syminfo.tickerid, input("1D", title="Reset Interval"), time)

newSession = iff(change(interval), 1, 0)

one = (high > high[1]) and (low > low[1])
two = (high < high[1]) and (low < low[1])
three = (high > high[1]) and (low < low[1])
four = (high < high[1]) and (low > low[1])
five = (high == high[1]) and (low > low[1])
six = (high > high[1]) and (low == low[1])
seven = (high < high[1]) and (low == low[1])
eight = (high == high[1]) and (low < low[1])

//formula
onex = +2 
twox = -2
threex = 0
fourx = 0
fivex = +1
sixx = +1
sevenx = -1 
eightx = -1

formula = (high > high[1]) and (low > low[1]) ? onex : (high < high[1]) and (low < low[1]) ? twox : (high > high[1]) and (low < low[1]) ? threex : (high < high[1]) and (low > low[1]) ? fourx : (high == high[1]) and (low > low[1]) ? fivex : (high > high[1]) and (low == low[1]) ? sixx : (high < high[1]) and (low == low[1]) ? sevenx : (high == high[1]) and (low < low[1]) ? eightx : 0
BuySell = sum(formula, 1)

BSsum : iff(newSession, BuySell, BSsum[1]+BuySell)

Kolor1 = (BSsum > 0)==true
Kolor2 = (BSsum < 0)==true

plot(BSsum, style=plot.style_columns, color=Kolor1?color.green:Kolor2?color.red:na, linewidth=3, transp=0, title="Buy/Sell Pressure")```

Answer 1

它不必包装，如果要在 Security（）中传递这些可变变量，则必须包装函数内部的变量。您的变量基于 Security 的数据，但并未传递给它。

要使脚本在v4中工作，您需要首先声明变量，然后通过：= 操作员分配新值：

BuySell = sum(formula, 1)

BSsum = 0.0
BSsum := newSession ? BuySell : BSsum[1] + BuySell

Kolor1 = (BSsum > 0)==true
Kolor2 = (BSsum < 0)==true

plot(BSsum, style=plot.style_columns, color=Kolor1?color.green:Kolor2?color.red:na, linewidth=3, transp=0, title="Buy/Sell Pressure")
