5 EMA pine 脚本给出了错误的结果

Question

Below is pine script. Why it is marking the highlighted candles as alert if none of the criteria is matching.

ema5 = ta.ema(close, 5 )

plotshape( close[1]>ema5 and low[1]>ema5  , title="AlertC", text="Alert",color=color.new(#FF000D,50), location=location.belowbar, style=shape.labeldown, size=size.tiny, textcolor=color.white)

Answer 1

You are using the [] history reference operator in your condition. That means, you are checking if the previous close and previous low prices are greater than the current ema5 .

You should look at the ema line on a bar and compare its value with the previous candle's low and close price. Where you marked "incorrect" seems to be correct. The previous candle's low is above the ema line at 09:15.
