Historic Crypto

An open source Python library for scraping Historical Cryptocurrency data.

This library scrapes coinmarketcap.com to collect historical Cryptocurrency data, returning a Pandas DataFrame. The HistoricalData class returns all attributes (Open, Close, High, Low, Volume, Market_Cap) of the selected cryptocurrency, whilst the MultipleHistoricalData accepts a list of cryptocurrencies and returns a single attribute of the corresponding cryptocurrencies.

Installation

From Python:

pip install Historic-Crypto
from Historic_Crypto import HistoricalData
from Historic_Crypto import MultipleHistoricalData

Usage

If you are unsure of the correct 'ticker' to scrape:

pip install Historic-Crypto
from Historic_Crypto import HistoricalData
HistoricalData(start_date = '', ticker = '').find_all_tickers()

Returns a Pandas DataFrame containing the columns "Name" and "Symbol", which indicate the Name - Symbol pairs of available cryptocurrencies. The "Symbol" is required as the corresponding 'ticker' input argument of other class methods:

pip install Historic-Crypto
from Historic_Crypto import HistoricalData

dataset = HistoricalData(start_date = '2013-06-06',
                        end_date = '2015-01-01',
                        ticker = 'BTC').retrieve_data()

Returns a Pandas DataFrame 'dataset', which contains the Open, Close, High, Low, Volume and Market Capitalisation of Bitcoin between 2013-06-06 and 2015-01-01, indexed by Date.

pip install Historic-Crypto
from Historic_Crypto import HistoricalData

dataset = HistoricalData(start_date = '2013-06-06',
                        ticker = 'BTC').retrieve_data()

Returns a Pandas DataFrame 'dataset', which contains the Open, Close, High, Low, Volume and Market Capitalisation of Bitcoin between 2013-06-06 and today, indexed by Date.

pip install Historic-Crypto
from Historic_Crypto import MultipleHistoricalData

dataset = MultipleHistoricalData(tickers = ['BTC','ETH'], 
                                attribute = 'Open', 
                                start_date = '2015-01-01', 
                                end_date = '2019-01-01').retrieve_data()

Returns a Pandas DataFrame 'dataset', which contains the Open 'attribute' of Bitcoin and Etherium between 2015-01-01 and today, indexed by Date. Please note that 'NaN' rows are present in the output, which can be subsequently processed.
