我正在定义一个函数Heiken Ashi,它是技术分析中流行的图表类型之一.我正在使用Pandas编写一个函数,但没有遇到任何困难.这就是Heiken Ashi [HA]的样子 -

                 Heikin-Ashi Candle Calculations
           HA_Close = (Open + High + Low + Close) / 4
           HA_Open = (previous HA_Open + previous HA_Close) / 2
           HA_Low = minimum of Low, HA_Open, and HA_Close
           HA_High = maximum of High, HA_Open, and HA_Close

               Heikin-Ashi Calculations on First Run
            HA_Close = (Open + High + Low + Close) / 4
                   HA_Open = (Open + Close) / 2
                           HA_Low = Low
                           HA_High = High

在使用for循环和纯python的各种网站上有很多东西,但我认为Pandas也可以做得很好.这是我的进步 -

   def HA(df):

       df['HA_Close']=(df['Open']+ df['High']+ df['Low']+ …
