Automated dollar cost averaging for BTC, LTC, BCH and ETH on GDAX.
If you only have a Coinbase account you'll need to also sign into GDAX. Make sure you have a bank account linked to one of these for ACH transfers.
Procure a GDAX API key for yourself by visiting www.gdax.com/settings/api. Do not share this API key with third parties!
Build the binary:
$ go build ./
Then run it:
./dcagdax --help
usage: dcagdax --every=EVERY [<flags>]
Flags:
--help Show context-sensitive help (also try --help-long and
--help-man).
--coin=BTC Which coin you want to buy: BTC, LTC, BCH or ETH (default 'BTC').
--every=EVERY How often to make purchases, e.g. 1h, 7d, 3w.
--usd=USD How much USD to spend on each purchase. If unspecified, the
minimum purchase amount allowed will be used.
--until=UNTIL Stop executing trades after this date, e.g. 2017-12-31.
--trade Actually execute trades.
--autofund Automatically initiate ACH deposits.
--version Show application version.
Run the dcagdax binary with an environment containing your API credentials:
$ GDAX_SECRET=secret \
GDAX_KEY=key \
GDAX_PASSPHRASE=pass \
./dcagdax --help
Be aware that if you set your purchase amount near 0.01 BTC (the minimum trade amount) then an upswing in price might prevent you from trading.
Q: Why do I not see any trading activity from the bot?
A: If you have other BTC trades on your account, the bot will detect that as a cost-averaged purchase and wait until the next purchase window. This is for people who want to "set it and forget it," not day traders!
Q: Why would I use this instead of Coinbase's recurring purchase feature?
A: The fees on recurring purchases (currently a minimum of $2.99 per purchase!) can add up quickly. This side-steps those costs by automating free ACH deposits into your exchange account & submitting market orders to exchange with BTC.
Q: How should I deploy this?
A: You could run this as a periodic cronjob on your workstation or in the cloud. Just be sure your API key & secret are not made available to anyone else as part of your deployment!
Q: Can this auto-withdraw coins into a cold wallet?
A: Not currently, but pull requests are welcome!
Q: Which coins can I purchase?
A: We support all of GDAX's products: BTC, LTC, BCH and ETH.
Q: Can I buy you a beer?
A: BTC 13N2g3MedU2mc6TzQWEE7kBoTCj6Ajyzpw
