没有行延续的 Pine Script 错误行尾

如何解决没有行延续的 Pine Script 错误行尾

我正在考虑在 pine 脚本上创建一条平均三个的趋势线。到目前为止，如果我不使用 3 的平均值，它可以工作，但如果我使用，它会出现错误：不匹配的输入“看跌”期待“没有行延续的行尾”。

trendLength_1 = input(title = "Trend Length_1:",defval = 10)
trendLength_2 = input(title = "Trend Length_2:",defval = 20)
trendLength_3 = input(title = "Trend Length_3:",defval = 30)

trend_1 = lowest(security_low,trendLength_1) + ((highest(security_high,trendLength_1) - lowest(security_low,trendLength_1)) / 2)
trend_2 = lowest(security_low,trendLength_2) + ((highest(security_high,trendLength_2) - lowest(security_low,trendLength_2)) / 2)
trend_3 = lowest(security_low,trendLength_3) + ((highest(security_high,trendLength_3) - lowest(security_low,trendLength_3)) / 2)
trend = (0.5 * trend_1) + (0.3 * trend_2) + (0.2 * trend_3)

bearish = true

for i = 0 to trendConfirmationLength - 1
        bearish := bearish and (security_close[i] < trend[i])

如果有人能发现语法错误，我们将不胜感激。谢谢！
