如何在 Python 中使用 pandas_ta 库添加 ichimoku？

Question

https://github.com/twopirllc/pandas-ta#overlap-33

import pandas_ta as ta
import pandas as pd


ichimoku = ta.ichimoku(df['high'], df['low'], df['close'])
df = pd.concat([df, ichimoku], axis=1)

TypeError: cannot concatenate object of type '<class 'tuple'>'; only Series and DataFrame objs are valid

Answer 1

ichimoku returns two data frames. One returns the high and low indicators, and the other returns the look-ahead indicator, so combining them requires a data frame for each.

import yfinance as yf
import pandas_ta as ta
import pandas as pd

df = yf.download("AAPL", start="2021-01-01", end="2022-01-01")

ichimoku = ta.ichimoku(df['High'], df['Low'], df['Close'])
df = pd.concat([df, ichimoku[0], ichimoku[1]], axis=1)

df.head()
