python - 在蜡烛图上添加信号

Question

我想在我的图表上绘制信号，有没有办法在烛台上绘制信号？我做了以下并卡住了:(

!pip install yfinance
!pip install mplfinance
import yfinance as yf
import mplfinance as mpf
import numpy as np 
import pandas as pd 

df=yf.download('BTC-USD',start='2008-01-04',end='2021-06-3',interval='1d')

buy=np.where((df['Close'] > df['Open']) & (df['Close'].shift(1) < df['Open'].shift(1),1,0)

fig = plt.figure(figsize = (20,10))
mpf.plot(df,figsize=(20,12),type ='candle',volume=True);

# any idea how to add the signal?

Answer 1

import yfinance as yf
import mplfinance as mpf
import numpy as np 

df = yf.download('BTC-USD', start='2008-01-04', end='2021-06-3', interval='1d').tail(50)

buy = np.where((df['Close'] > df['Open']) & (df['Close'].shift(1) < df['Open'].shift(1)), 1, np.nan) * 0.95 * df['Low']

apd = [mpf.make_addplot(buy, scatter=True, markersize=100, marker=r'$\Uparrow$', color='green')]

mpf.plot(df, type='candle', volume=True, addplot=apd)

为了更好的可视化，我刚刚添加了 .tail()。
