松树脚本接收"error at syntax"

Question

我收到这个错误：

输入处的语法错误"结果"；

我是pine脚本的新手，不知道如何解决这个问题；有人能帮忙吗？

//@version=4
len = input(title="Length", type=input.integer, defval=20)
var result = 0.0 

di_func(dirup) =>
TrueRange = max(max(high-low, abs(high-nz(close[1]))), abs(low-nz(close[1])))
DirectionalMovementPlus = high-nz(high[1]) > nz(low[1])-low ? max(high-nz(high[1]), 0): 0
DirectionalMovementMinus = nz(low[1])-low > high-nz(high[1]) ? max(nz(low[1])-low, 0): 0
SmoothedTrueRange = 0.0
SmoothedDirectionalMovementPlus = 0.0    
SmoothedDirectionalMovementMinus = 0.0
SmoothedTrueRange = nz(SmoothedTrueRange[1]) - (nz(SmoothedTrueRange[1])/len) + TrueRange
SmoothedDirectionalMovementPlus = nz(SmoothedDirectionalMovementPlus[1]) - (nz(SmoothedDirectionalMovementPlus[1])/len) + DirectionalMovementPlus
SmoothedDirectionalMovementMinus = nz(SmoothedDirectionalMovementMinus[1]) - (nz(SmoothedDirectionalMovementMinus[1])/len) + DirectionalMovementMinus
dirup == true ? result := SmoothedDirectionalMovementPlus / SmoothedTrueRange * 100 : result := SmoothedDirectionalMovementMinus / SmoothedTrueRange * 100


res = input(title="Resolution", type=input.resolution, defval="5")
s1 = security(syminfo.tickerid, res, di_func(true), gaps=true)
s2 = security(syminfo.tickerid, res, di_func(false), gaps=true)
bgcolor(s1>s2 ? color.new(color.green,70) : s1<s2 ? color.new(color.red,70) : na, title="Adx 5 bg")

错误的行被注释掉，并由更正替换
还添加了一个study()标记。

//@version=4
study("Script", "", overlay=true)
len = input(title="Length", type=input.integer, defval=20)
var result = 0.0 

di_func(dirup) =>
TrueRange = max(max(high-low, abs(high-nz(close[1]))), abs(low-nz(close[1])))
DirectionalMovementPlus = high-nz(high[1]) > nz(low[1])-low ? max(high-nz(high[1]), 0): 0
DirectionalMovementMinus = nz(low[1])-low > high-nz(high[1]) ? max(nz(low[1])-low, 0): 0
SmoothedTrueRange = 0.0
SmoothedDirectionalMovementPlus = 0.0    
SmoothedDirectionalMovementMinus = 0.0
// SmoothedTrueRange = nz(SmoothedTrueRange[1]) - (nz(SmoothedTrueRange[1])/len) + TrueRange
// SmoothedDirectionalMovementPlus = nz(SmoothedDirectionalMovementPlus[1]) - (nz(SmoothedDirectionalMovementPlus[1])/len) + DirectionalMovementPlus
// SmoothedDirectionalMovementMinus = nz(SmoothedDirectionalMovementMinus[1]) - (nz(SmoothedDirectionalMovementMinus[1])/len) + DirectionalMovementMinus
// dirup == true ? result := SmoothedDirectionalMovementPlus / SmoothedTrueRange * 100 : result := SmoothedDirectionalMovementMinus / SmoothedTrueRange * 100
SmoothedTrueRange := nz(SmoothedTrueRange[1]) - (nz(SmoothedTrueRange[1])/len) + TrueRange
SmoothedDirectionalMovementPlus := nz(SmoothedDirectionalMovementPlus[1]) - (nz(SmoothedDirectionalMovementPlus[1])/len) + DirectionalMovementPlus
SmoothedDirectionalMovementMinus := nz(SmoothedDirectionalMovementMinus[1]) - (nz(SmoothedDirectionalMovementMinus[1])/len) + DirectionalMovementMinus
(dirup ? SmoothedDirectionalMovementPlus : SmoothedDirectionalMovementMinus) / SmoothedTrueRange * 100


res = input(title="Resolution", type=input.resolution, defval="5")
