为什么我不能从 mplfinance 导入烛台_ohlc

Question

So I have been able to successfully install mplfinance with pip and when I import it alone I receive no error. Though when I do: from mplfinance import candlestick_ohlc I get the error ImportError: cannot import name 'candlestick_ohlc' from 'mplfinance' I have checked command prompt again, and it says it has successfully installed mplfinance. Why am I receiving this error?

Answer 1

So from what I understand the Matplotlib for finance has changed so that:

To access the old API with the new mplfinance package installed, change statments

from:

from mpl_finance import 

to:

    from mplfinance.original_flavor import candlestick_ohlc

and then it should work fine.

Answer 2

You do not have to import 'candlestick_ohlc' anymore.

'mplfinance.plot()' defaults to ohlc style charts.

These links provide good examples. The second one uses candlesticks. You can change that arg.

Answer 3

the first thing you have to do is install the library with the command:

pip install mplfinance

after that you can call the resource like:

from mplfinance.original_flavor import candlestick_ohlc
