coinbase_trader

A python application to set complex Coinbase trading orders. Market orders, Limits, stop losses, and trailing stop losses by percent and value. Uses Coinbase API and your api_key or oauth2 credentials (https://coinbase.com/docs/api/authentication) to execute real trades through Coinbase. Nearly every Coinbase API function has been implemented so you can also send, receive, and request bitcoins or check your account information, transaction history, ect.

Requirements

coinbase_python library and its requirements (https://github.com/sibblegp/coinbase_python)

Example

from trader import Trader, CoinOrder
# oauth2 example setup can be seen in example.py of coinbase_python library
myTrader = Trader(api_key = 'my API key', logname = "mylog.txt")
# Setup order to Sell 0.5 bitcoin 10% lower than highest price seen by Trader.trade() 
# Use the optional price attribute to specify the max seen price so far, default is 0.
myTrader.setTrailingStopLossPercent(qty = 0.5, changeval = 10) 
# Setup order to Buy 0.5 bitcoin at 800 dollars per coin
myTrader.setLimitBuy(qty = 0.5, price = 800)
# Attempt to execute all trades once per sleep time until all trades have been executed
myTrader.trade(sleeptime = 60)

Notes

Can call functions from coinbase_python api via Trader.account object
Occasionally receive "No JSON Object could be decoded" errors from Requests library. TODO: try/except and retry once to see if that alleviates the problem.
TODO: option .trade() to run for a specified time interval before quitting
TODO: make .trade() optionally run in a seperate thread where .stoptrade() signals quitting then you could pass orders to that thread via user input.
TODO: preserve orderbook in a file and optionally reload the orderbook via an input to the python call this would be more useful once the threading feature above were added to save the user input and the other reason for this is to save the max seen value for trailing stop loss orders. The only time that max value is lost when the CoinOrder object is destroyed for any reason.
TODO: Setup as module with setup.py vs just importing
