A python application to set complex Coinbase trading orders. Market orders, Limits, stop losses, trailing stop losses by percent or value, and one starts another orders. 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.

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

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)

• Trader.trade() function can run for a specified length of time.
• Support has been added to easily run Trader.trade() in a seperate thread safely. Allowing you to add or remove orders from the orderbook easily (see testTrader.py for examples).
• Can call functions from coinbase_python api via Trader.account object (could be dangerous in multithreaded mode without Trader._executeLock mutex)
• 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
• TODO: I am contemplating adding btc-e support (through a module already created for btc-e or with the requests library used by coinbase_python) and an algorithm that will trade on its own accord. For example, the program could pull in historical data and run a predictive learning classifier model to either buy or sell your coins based on historical data (possibly an SVM classifier), this would be a more significant update.

So far just me Kevin-Roberts but contributions are greatly appreciated.

This program executes REAL bitcoin trades with money from your coinbase account using the Coinbase API. Use and trade with this program at your own risk as I am not liable for any losses incurred using this software.
