动量蜡烛突破

Question

我是新来的松树脚本，并试图写一个脚本。我想检查一下

1. 一支稍大的红色(动量)蜡烛，比普通的
2. 至少有两支蜡烛关闭在这支红色动量蜡烛的身体内。在这两支蜡烛之后，下一支蜡烛在相反的方向打破了前面的三支蜡烛。--

到目前为止，我已经写了下面的脚本，但我被困在它。

     //@version=4
     study("Momentum Candle",shorttitle="Momentum_Candles_80_Percent", overlay=true)

     
     body = abs(close-open)
     rng=high-low
     strongRed = body/rng>=0.80 and open > close and 

     plotchar(strongRed,location=location.belowbar,color=color.blue)

Answer 1

您必须使用[] brackets来选择特定的蜡烛，提供对系列expr1以前值的访问。expr2是条形图后面的数，必须是数字。浮标将被四舍五入。expr1\[expr2\]

//@version=4
study("Momentum Candle",shorttitle="Momentum_Candles_80_Percent", overlay=true)


body = abs(close-open)
rng=high-low
strongRed = body/rng>=0.80 and open > close[1]  and
                               open > close[2]  and
                               open > open[1]   and
                               open > open[2]   and
                               close < close[1] and
                               close < close[2] and
                               close < open[1]  and
                               close < open[2]  or
                               open < close[1]  and
                               open < close[2]  and
                               open < open[1]   and
                               open < open[2]   and
                               close > close[1] and
                               close > close[2] and
                               close > open[1]  and
                               close > open[2]
plotchar(strongRed,location=location.belowbar,color=color.blue)
