QuantConnect supports cryptocurrency backtesting and live trading. We launched 2017 with the Coinbase Pro (formerly GDAX) exchange.

Cryptocurrency trading is handled similarly to a forex transaction; however the exchanges do not provide the same holdings history as traditional forex brokerages so it has some unique challenges in live trading we will go into below.

One common stumbling block that users face designing algorithms with crypto currency is a misunderstanding of Cash modeling. Most crypto exchanges only support cash trading so you cannot place trades when you do not have the cash in your account. 'Cash' in this sense means any of the crypto coin types.

For example, if you have $100,000 USD; but no LTC in your portfolio - you cannot trade BTCLTC, and in order to trade BTCEUR you need EUR in your portfolio. This means you must make trading decisions based on the Cashbook. This holds your current balance of coins available.

// Fetch the number of BTC coins in your portfolio.
var btc = Portfolio.CashBook["BTC"].Amount;
# Fetch the number of BTC coins in your portfolio.
btc = self.Portfolio.CashBook["BTC"].Amount

Cryptocurrency is also sensitive to transaction fees so it is important to set the correct BrokerageModel. This also helps your backtesting restrictions behave as close as possible to the production live trading environment.

Coinbase Pro trades are currently available from 2015-06-15 to the present. The data in 2015 is somewhat spotty and unrealistic so we recommend starting your backtests from 2016 onwards. We have data on all currency pairs supported by Coinbase Pro.

We currently only have Coinbase Pro brokerage integration. For more information on using this data in your algorithm see the Initializing Algorithms.
