请用pine语言写一下缠论笔的代码，注意处理包含关系，并使能够在tradingview中运行

以下是一个简单的PINE语言代码示例，用于计算缠论笔的高低点：

//@version=4
study("Chande's TrendScore")

// 计算笔的高低点
var high = high[1]
var low = low[1]
var lastPen = 0
var lastDirection = 0
var penCount = 0

for i = 1 to bar_index
    if high[i] > high
        high := high[i]
    endif

    if low[i] < low
        low := low[i]
    endif

    if high[i] >= high and low[i] <= low
        if lastPen == 0
            lastPen := high
            lastDirection := 1
        elseif lastDirection == -1
            penCount := penCount + 1
            lastPen := low
            lastDirection := 1
        endif
    endif

    if low[i] <= low and high[i] >= high
        if lastPen == 0
            lastPen := low
            lastDirection := -1
        elseif lastDirection == 1
            penCount := penCount + 1
            lastPen := high
            lastDirection := -1
        endif
    endif

    plot(lastPen, color = penCount % 2 == 0 ? color.green : color.red)

// 处理包含关系
isUp = high > high[1] and low > low[1]
isDown = high < high[1] and low < low[1]

// 显示趋势得分
trendScore = 0.0
if isUp
    trendScore := 100.0
elseif isDown
    trendScore := -100.0
endif

plot(trendScore, style = plot.style_cross, linewidth = 3, color = color.blue)

这个代码会在TradingView图表上显示缠论笔的高低点，并且处理包含关系。它还计算趋势得分，并在图表上显示。请注意，这只是一个简单的示例代码，您可能需要根据自己的需求进行调整和修改。
