使用 mplfinance / matplotlib 创建简单的过滤器功能区

使用finplot，这很容易：

import finplot as fplt
import yfinance

df = yfinance.download('GOOG')
ax = fplt.create_plot('Alphabet 1D')
fplt.candlestick_ochl(df[['Open', 'Close', 'High', 'Low']], ax=ax)

# create a ribbon around MA200/50
df['ma200'] = df.Close.rolling(200).mean()
df['ma50'] = df.Close.rolling(50).mean()
df['one'] = 1
fplt.volume_ocv(df[['ma200','ma50','one']], candle_width=1, ax=ax.overlay(scale=0.1))

fplt.show()
