(This means that if there are rows in your DataFrame that exist but contain only NaN values, these rows will still appear on the plot even if show_nontrading=False)įor example, in the chart below, you can easily see weekends, as well as a gap at Thursday, November 28th for the U.S. show_nontrading=False (the default value) will show only dates (or datetimes) that have actual rows in the data. show_nontrading=True will display all dates (all time intervals) between the first time stamp and the last time stamp in the data (regardless of whether rows exist for those dates or datetimes).This is because, when data is retrieved from an exchange or other market data source, that data typically will not include rows for non-trading days (weekends and holidays for example). (There are simply no rows for those dates or datetimes). Note that for these purposes non-trading intervals are those that are not represented in the data at all. Non-trading days can be displayed with the show_nontrading keyword. However, sometimes people like to see these gaps, so that they can tell, with a quick glance, where the weekends and holidays fall. Non-trading days are simply not shown (since there are no prices for those days). Notice, in the above chart, there are no gaps along the x-coordinate, even though there are days on which there was no trading. plot ( daily, type = 'candle', mav = ( 3, 6, 9 ), volume = True ) plot ( daily, type = 'candle', mav = ( 3, 6, 9 )) use a tuple or list of integers for multiple moving averages.use a scalar for a single moving average.We can also plot moving averages with the mav keyword Other plot types can be specified with the keyword argument type, for example, type='candle', type='line', type='renko', or type='pnf' mpf. The default plot type, as you can see above, is 'ohlc'. tail ( 3 ) (20, 5)Īfter importing mplfinance, plotting OHLC data is as simple as calling mpf.plot() on the dataframe import mplfinance as mpf mpf. read_csv ( 'examples/data/SP500_NOV2019_Hist.csv', index_col = 0, parse_dates = True ) daily. For example, import pandas as pd daily = pd. Start with a Pandas DataFrame containing OHLC data. You can reach me at or, if you prefer, provide feedback or a ask question on our issues page. I am very interested to hear from you regarding what you think of the new mplfinance, plus any suggestions you may have for improvement. Where data is a Pandas DataFrame object containing Open, High, Low and Close data, with a Pandas DatetimeIndex.ĭetails on how to call the new API can be found below under Basic Usage, as well as in the jupyter notebooks in the examples folder. The most common usage is then to call mpf. The conventional way to import the new API is as follows: import mplfinance as mpf (The old API is still available within this package see below). More importantly, the new API automatically does the extra matplotlib work that the user previously had to do "manually" with the old API. It interfaces nicely with Pandas DataFrames. This repository, matplotlib/mplfinance, contains a new matplotlib finance API that makes it easier to create financial plots.
