内条着色只要在母条 Amibroker AFL 范围内答案

【问题标题】：Inside Bar coloring as long as inside the range of mother bar Amibroker AFL内条着色只要在母条 Amibroker AFL 范围内
【发布时间】：2020-03-14 04:39:20
【问题描述】：

n= -1; Color = IIf((High < Ref(High,n) & Low > Ref(Low,n)), colorRed , colorWhite); Plot( Close, "Colored Price", Color, styleBar );

红色箭头指向条是母条，蓝色箭头指向白色条是母条范围内的内部条。所以我正在尝试将当前栏与母栏进行比较，如果当前栏在母栏的范围内，则直接比较前一个栏，但如果代码条件为真但它不工作不知道为什么，我尝试添加递减 n 值。请参考图片以获得更好的清晰度

n= -1; Color = IIf((High < Ref(High,n) & Low > Ref(Low,n)), colorRed && n= n--, colorWhite); Plot( Close, "Colored Price", Color, styleBar );

我发现写出 for 循环更容易

function InsideBarColor() {

    local state;
    local isInsideBar;
    local index;
    
    local insideHigh;
    local insideLow;
    local priceColor;
    
    state = 0;
    isInsideBar = Inside();
    priceColor = colorDefault;
    
    for(index = 1; index < BarCount; index += 1) {
    
        if (state == 0 && isInsideBar[index] == True) {
        
            // Record the High/Low of the first inside bar.
            insideHigh = High[index-1];
            insideLow = Low[index-1];
            state = 1;
            priceColor[index] = colorRed;
        
        } else if(state == 1) {
        
            if (High[index] > insideHigh || Low[index] < insideLow) {
                // Price broke out of range
                priceColor[index] = colorWhite;
                state = 0;
            } else {
                // Price still inside range
                priceColor[index] = colorBlue;
            }
        
        } else {
            priceColor[index] = priceColor[index -1]; 
        }
    
    }
    
    return priceColor;

}

colors = InsideBarColor();
