• Support API calls of top cryptocurrency exchanges

• Support trading and analysis tools for cryptocurrency market

The project aims to answer the following two questions:

1. How to get historical data, especially a long period, in a single query?

2. How to send exchange API query in an elegent fashion?

Python 3.5+

You can install it via pip for static version

pip install libcryptomarket

or development version

pip install git+https://github.com/libcryptomarket/libcryptomarket.git

This library is to extend the library ccxt on more powerful functions. So the supported exchanges are same as ccxt while a few exchanges are extended with the following features. You just need to import the exchange from libcryptomarket.

from datetime import datetime
import libcryptomarket

poloniex = libcryptomarket.poloniex()
candles = libcryptomarket.fetch_candles(
    symbol="ETH/BTC",
    start_time=datetime(2018, 1, 1),
    end_time=datetime(2018, 1, 30),
    frequency="30m")

from datetime import datetime
import libcryptomarket

poloniex = libcryptomarket.poloniex()
candles = libcryptomarket.fetch_latest_candles(
    symbols=["ETH/BTC", "LTC/BTC"],
    frequency="30m",
    frequency_count=5)

Console usage is for exporting historical data.

request-candles --exchange poloniex --symbols ETH/BTC LTC/BTC --frequency 30m --start-time 2018-01-01 --end-time 2018-01-31 --output test.csv
