【问题描述】：
我只是想用内置简单移动平均函数的值来分配我的变量 (movingAv)。但是，对于上面带有我的变量声明的行，我收到错误“找不到函数或函数引用 ta.sma”。
在代码编辑器中，“ta.sma”已变为蓝色，因此编辑器必须识别该功能。我从其他指标中查看了类似的代码，它看起来是一样的。
任何想法这里发生了什么？
非常感谢 亚当
study(\"Renko Reversal alert\", overlay=true)
src = close
len = 10
movingAv = ta.sma(src, len)
plot(movingAv, color=color.blue, title=\"MA\")
//Buy signal if a bearish renko brick is followed by a bullish brick
//Sell signal if a bullish brick is followed by a bearish brick
long = close[1] > open[1] and close[2] < open[2]
long = close[1] < open[1] and close[2] > open[2]
longCross = open[1] < movingAv and close[1] > movingAv
shortCross = open[1] > movingAv and close[1] < movingAv
//Use these alerts to create server-side alerts (right-click on one of the buy or sell arrows on the chart and choose \"add alert\")
alertcondition(long == true, title = \'Long opportunity\', message = \'{{ticker}}\')
alertcondition(short == true, title = \'Short opportunity\', message = \'{{ticker}}\')
alertcondition(longCross == true, title = \'Long SMA XOver\', message = \'{{ticker}}\')
alertcondition(longCross == true, title = \'Short SMA Xover\', message = \'{{ticker}}\')
//Use this to customize the look of the arrows to suit your needs.
