我如何将这两个脚本代码合并到一个指标中？

Question

我无法将这两个脚本代码合二为一。 我尝试了所有我知道的方法，但我无法将这两个代码结合起来。 第一个代码标识通道，而第二个代码确定通道的中线。 我真正想要做的是绘制第三条线，穿过通道线并将通道分成两部分。 有什么帮助吗？

第一个脚本是：

indicator("Nadaraya-Watson Envelope", 'NWEn', overlay=true,max_bars_back=1000,max_lines_count=500,max_labels_count=500)
length = input.float(500,'Window Size',maxval=500,minval=0)
h      = input.float(8.,'Bandwidth')
mult   = input.float(3.) 
src    = input.source(close,'Source')
showLabels = input.bool(false, 'Show ▲ ▼ Labels (repaint issue)')
lw = input.int(1, 'Line Width', [1,2,3,4])
dn_col = input.color(#39ff14,'Colors',inline='col')
up_col = input.color(#ff1100,'',inline='col')
//----
n = bar_index
var k = 2
var upper = array.new_line(0) 
var lower = array.new_line(0) 

ls = line.style_solid

lset(l,x1,y1,x2,y2,col,lineStyle)=>
    line.set_xy1(l,x1,y1)
    line.set_xy2(l,x2,y2)
    line.set_color(l, col)
    line.set_width(l,lw)
    line.set_style(l, lineStyle)


//----

if barstate.isfirst
    for i = 0 to length/k-1
        array.push(upper,line.new(na,na,na,na))
        array.push(lower,line.new(na,na,na,na))

//----
line up = na
line dn = na

//----
cross_up = 0.
cross_dn = 0.


if barstate.islast
    y = array.new_float(0)
    
    sum_e = 0.
    for i = 0 to length-1
        sum = 0.
        sumw = 0.
        
        for j = 0 to length-1
            w = math.exp(-(math.pow(i-j,2)/(h*h*2)))
            sum += src[j]*w
            sumw += w
        
        y2 = sum/sumw
        sum_e += math.abs(src[i] - y2)
        array.push(y,y2)

    mae = sum_e/length*mult
    
    for i = 1 to length-1
        y2 = array.get(y,i)
        y1 = array.get(y,i-1)
        up := array.get(upper,i/k)
        dn := array.get(lower,i/k)

        
        lset(up,n-i+1,y1 + mae,n-i,y2 + mae, y2 > y1 ? #ff1100 : #39ff14, ls)
        lset(dn,n-i+1,y1 - mae,n-i,y2 - mae, y2 > y1 ? #ff1100 : #39ff14, ls)

        for j = 0 to math.min(499, n - 1) by 1
            w = math.exp(-(math.pow(i - j, 2) / (h * h * 2)))
            sum += src[j] * w
            sumw += w
            sumw
        y2 := sum / sumw
        d = y2 - y1

        l := array.get(ln, i)
        line.set_xy1(l, n - i + 1, y1)
        line.set_xy2(l, n - i, y2)
        line.set_color(l, y2 > y1 ? col : col)
        line.set_width(l, lw)
        line.set_style(l, line.style_solid)

        if d > 0 and y1_d < 0 and showLabels
            label.new(n - i + 1, src[i], '▲', color=#00000000, style=label.style_label_up, textcolor=#39ff14, textalign=text.align_center)
        if d < 0 and y1_d > 0 and showLabels
            label.new(n - i + 1, src[i], '▼', color=#00000000, style=label.style_label_down, textcolor=#ff1100, textalign=text.align_center)

        y1 := y2
        y1_d := d
        y1_d

长度变量限制为 252。因为 tradingview 限制为绘制 500 条线。

Answer 2

2 的组合很棒，如果只在估计器为绿色和红色的简称时打印长的话会更好......如果那可能吗？ 我希望结合 2x NWE，但我不编码 pffft。 好一个丹
