Incompatibility with talib (expected numpy.ndarray, got DataFrame)

[finisky]

Describe bug

talib cannot accept dataframe as input:

Traceback (most recent call last):
  File "/data/1.py", line 7, in <module>
    df['SMA_5'] = ta.SMA(df['Close'], timeperiod=5)
  File "/data/miniconda3/envs/a/lib/python3.10/site-packages/talib/__init__.py", line 64, in wrapper
    result = func(*_args, **_kwds)
TypeError: Argument 'real' has incorrect type (expected numpy.ndarray, got DataFrame)

It works for yf 0.2.44, but not work for 0.2.46+.

Simple code that reproduces your problem

import talib as ta
import yfinance as yf

df = yf.download("MSFT", period='5d')
df['SMA'] = ta.SMA(df['Close'], timeperiod=3)

It works for yf 0.2.44, but not work for 0.2.46+.

Double-check this. I get opposite.

Cause:

After issues #2068 #2100 , yf.download("MSFT") returns by default now a DataFrame with an extra level Ticker

Fix:

Either use

df = yf.download("MSFT", period='5d', multi_level_index=False)

or

df = yf.Ticker("MSFT").history()
