TradingView脚本报错：找不到'tostring'函数或引用，求解决方案

Pine Script v5 已将数值转字符串的函数从旧版本的 tostring() 重命名为 str.tostring()，你代码中使用了已废弃的旧函数名，因此触发"Could not find function or function reference 'tostring'"报错。

把代码里所有的 tostring() 替换为 str.tostring() 就能解决这个问题。

//@version=5
indicator("Consecutive Candles Alert", shorttitle="CC Alert", overlay=false)

// Input parameters
length = input.int(5, minval=1, title="Consecutive Candles Length")
symbolToWatch = input.symbol("EURUSD", title="Symbol to Watch")
timeFrameToWatch = input.timeframe("1", title="Timeframe to Watch")

// Calculate consecutive candles of the same direction
isBullish = close > open
isBearish = close < open
consecBullish = ta.barssince(isBullish) + 1
consecBearish = ta.barssince(isBearish) + 1

// Check for the condition and trigger alert
alertCondition = (consecBullish >= length and isBearish) or (consecBearish >= length and isBullish)
alert("Consecutive Candles Alert: " + syminfo.tickerid + " - " + str.tostring(timeFrameToWatch), alert.freq_once_per_bar)

// Plot consecutive candles count
consecCount = alertCondition ? (isBullish ? consecBullish : consecBearish) : na
plotshape(consecCount, title="Consecutive Candles Count", location=location.top, color=color.red, style=shape.labelup, textcolor=color.white)

// Plot candles
plotcandle(open, high, low, close, color=isBullish ? color.new(color.green, 50) : color.new(color.red, 50))

// Set up alert message
