This is the starting point of a python package [*]_ to automatically *download* data and *update* database with *crypto-currency* data (bitcoin, ether, litecoin, etc.) from different API exchanges (allow only Binance, Bitmex, Bitfinex, GDAX, Kraken and Poloniex for the moment).
Presentation:
=============
The ``dccd`` package allow you two main methods to download data. The first one is recommended to download data at high frequency (**minutely** or **tick by tick**), and the second one is recommended to download data at a lower frequency (**hourly** or **daily**):
- **Continuous Downloader** ``dccd.continuous_dl``:
Download and update continuously data (orderbook, trades tick by tick, ohlc, etc) and save it in a database. *Currently only support Bitfinex and Bitmex exchanges*.
- **Historical Downloader** ``dccd.histo_dl``:
Download historical data (ohlc, trades, etc.) and save it. *Currently only support Binance, GDax, Kraken and Poloniex exchanges*.
Historical Downloader:
----------------------
The **'dccd.histo_dl'** module contains a main class and four classes to download and update data for each exchange, and a module **'date_time'** to manage specific time format needed for each API.
The four classes to download historical data are **FromBinance**, **FromGDax**, **FromKraken** and **FromPoloniex**. All have the same methods and almost the same parameters:
- **__init__(path, crypto, span, fiat(optional), form(optional))** initialisation with **path** is the path where save the data (string), **crypto** is a crypto currency (string) and **span** is the interval time between each observation in seconds (integer) or can be a string as 'hourly', 'daily', etc. (see details on the doc string). The optional parameters are **fiat** the second currency (default is 'USD' and 'USDT' for poloniex and binance) and **form** the format to save the data (default is 'xlsx').
- **import\_data(start, end)** download data with **start** and **end** the timestamp (integer) or the date and time (string as 'yyyy-mm-dd hh\:mm\:ss'), respectively of the first observation and the last observation (default are special parameters **start='last'** allow the last data saved and **end='now'** allow the last observation available). Exclusion: Kraken don't allow the **end** parameter and provide only the thousand last observations.
- **save(form(optional), by(optional))** save the data with **form** the format of the saved data (default is 'xlsx') and **by** is the "size" of each saved file (default is 'Y' as an entire year). Exclusion: This optional parameters are in progress, let the default parameter for the moment, other are not allow.
- **get\_data()** returns the data frame without any parameter.
Method chaining is available.
