        # What is this?
        
        This is a Python script you can use to automatically buy Bitcoin, Ethereum,
        Litecoin, and more using the Coinbase Pro API. By default, it buys these 3 currencies,
        weighted by market cap (as reported by
        [coinmarketcap.com](https://coinmarketcap.com/)), using a form of [dollar cost
        averaging](https://www.bogleheads.org/wiki/Dollar_cost_averaging) according to
        the following logic (assuming default values):
        
        1. Check current balances of fiat (USD by default), BTC, ETH, and LTC
        1. If the fiat balance is above \$25, buy BTC, ETH, and LTC weighted by market
           cap, as follows:
           - If there's enough fiat available, place 5 discounted limit orders at the
             current price minus 0.5% up to 4.5%, each order with 1/5th of the remaining
             amount to buy for each coin (see
             "[Details on the orders placed](#details-on-the-orders-placed)", below)
           - If there isn't enough USD available, place 1 buy order at 0.5% off the
             current price (see
             "[Order Minimums](https://support.cbpro.com/customer/portal/articles/2725970-trading-rules)")
        1. If the fiat account balance is below \$25 (or whatever you specify), withdraw
           coins to desired addresses
        
        In effect, this script mimmicks the behaviour of a market cap weighted index
        fund, but without the fees. It also only supports the coins that trade on Coinbase Pro
        (because that's the only exchange that has an API for ACH deposits AFAIK).
        
        You can also use the same script to schedule deposits from your bank account
        periodically, such as when you're paid. The parameters may be configured to suit
        your preferences, such as which coins to buy, external balances, discount
        values, number of steps, etc.
        
        Orders, deposits, and withdrawals are tracked in a SQLite DB, and the withdrawn
        balances are added to the balances on Coinbase Pro to make sure the weights are
        maintained over time. The SQLite DB can be swapped out for any DB that
        SQLAlchemy supports.
        
        A note on the default parameters: it's likely you'll want to change
        `--starting-discount`, `--discount-step`, or `--order-count`. The more spread
        out the orders are (i.e., difference between the current price and the lowest
        priced order), the longer they will take to fill (if they fill), and the closer
        the orders are, the more likely you are to miss out on bigger price drops. You
        should consider your appetite for risk and how much you want to optimize for
        catching those dips vs. not missing out on gains. There is no magic here. My
        personal advice is to stick somewhat close to the defaults, and try to
        continuously deposit a little more fiat every week to spread the risk but also
        catch some dips.
        
        Ideally, this script would help to make sure that when we dip—
        
        ![dip](buy-the-dip.gif)
        
        **we buy**.
        
        # Will you help me set this up?
        
        Feel free to create a GitHub issue if you need help, and I will help you if it
        doesn't require too much effort on my part. I generally do not provide
        consulting services for free. If you want to hire me, find my contact details
        through the Internet and contact me using whatever your preferred contact method
        is.
        
        # USE AT OWN RISK
        
        Duh. Not my fault if you lose everything.
        
        Unless you place **absolute trust** in me, some guy from the Internet, I suggest
        you clone the repo and build your own container to protect yourself from any
        type of funny business.
        
        # How do I use it?
        
        The package itself can be used as a Docker container, or by installing the
        pip package with `pip install optimal-buy-cbpro`. Using the Docker container
        is recommended to avoid Python environment issues. Instructions for running
        with Docker and systemd are as follows:
        
        1.  Get yourself a hardware wallet, such as a
            [Ledger](https://www.ledgerwallet.com/) or [TREZOR](https://trezor.io/).
        1.  Set up a Coinbase Pro account, and link your bank account
        1.  Create a Coinbase Pro API key with view, trade, manage, transfer, and bypass-2fa
            permissions
        1.  Determine the payment_method_id value by using the
            [Coinbase Pro API](https://docs.pro.coinbase.com/#payment-methods) (you can use your browser's
            developer toolbar,
            [here's a quick video showing how](https://youtu.be/NmSEBGbn7Mc))
        1.  Get a machine somewhere (GCE, EC2, Digital Ocean) with Docker and systemd
        1.  Copy systemd files over:
        
                $ sudo cp systemd/optimal-buy-cbpro-*.{service,timer} /etc/systemd/system
        
        1.  Edit [`/etc/systemd/system/optimal-buy-cbpro-buy.service`](optimal-buy-cbpro-buy.service),
            [`/etc/systemd/system/optimal-buy-cbpro-buy.timer`](optimal-buy-cbpro-buy.timer),
            [`/etc/systemd/system/optimal-buy-cbpro-deposit.service`](optimal-buy-cbpro-deposit.service), and
            [`/etc/systemd/system/optimal-buy-cbpro-deposit.timer`](optimal-buy-cbpro-deposit.timer) to your liking. Make sure you:
        
            - Change the BTC, ETH, and LTC withdrawal addresses to deposit the coins
              into your wallet (use a Ledger or TREZOR)
            - Pop in the correct API keys
            - Check the deposit amount (start with something small, like \$150, to make
              sure it actually works first)
            - Check the timer dates (it would be sensible to change the hh:mm so your
              script doesn't run the same time as everyone else's), make sure the deposit
              timer fires according to your deposit schedule (keeping in mind that ACH
              takes 2-5 business days to clear, typically)
            - Consider specifying your external balances in order to accurately
              calculate the weights and amounts to purchase
        
        1.  Enable the systemd units:
        
                $ sudo systemctl enable optimal-buy-cbpro-buy.service
                $ sudo systemctl enable optimal-buy-cbpro-buy.timer
                $ sudo systemctl enable optimal-buy-cbpro-deposit.service
                $ sudo systemctl enable optimal-buy-cbpro-deposit.timer
        
        1.  Start the systemd timers:
            $sudo systemctl start optimal-buy-cbpro-buy.timer$ sudo systemctl start optimal-buy-cbpro-deposit.timer
        
        1.  Enjoy!

            Default coins are as follows:

                  "BTC":{
                    "name":"Bitcoin",
                    "withdrawal_address":null,
                    "external_balance":0
                  },
                  "ETH":{
                    "name":"Ethereum",
                    "withdrawal_address":null,
                    "external_balance":0
                  },
                  "LTC":{
                    "name":"Litecoin",
                    "withdrawal_address":null,
                    "external_balance":0
                  }
                }
        
        # Details on the orders placed
        
        By default, there are 5 orders placed (for each currency) in steps of 1%,
        starting at a 0.5% discount from the current price. To illustrate, if the
        current price was $100 (per LTC, let's say), and you had$100 to buy, the orders
        would look like this:
        
        | Order | Size       | Price  |
        | ----- | ---------- | ------ |
        | 1     | 0.2010 LTC | \$99.5 |
        | 2     | 0.2030 LTC | \$98.5 |
        | 3     | 0.2051 LTC | \$97.5 |
        | 4     | 0.2072 LTC | \$96.5 |
        | 5     | 0.2094 LTC | \$95.5 |
        
        Furthermore, the amount of each currency to buy will be based on the current
        market cap weighting of each coin. For example, at the time of writing the
        weights are:
        
        | Coin | Market Cap (USD)  | Weight |
        | ---- | ----------------- | ------ |
        | BTC  | \$195,824,365,435 | 0.791  |
        | ETH  | \$46,080,472,372  | 0.186  |
        | LTC  | \$5,592,776,540   | 0.023  |
        
        So if your USD account had \$1000, the amount purchased of each would
        become:
        
        | Coin | Weight | Amount Purchased |
        | ---- | ------ | ---------------- |
        | BTC  | 0.791  | \$791            |
        | ETH  | 0.186  | \$186            |
        | LTC  | 0.023  | \$23             |
        
        # Caveats/limitations
        
        - If you try to trade manually or using some other bot at the same time,
          you're probably going to have a bad time
        - You might have a few dollars (<\$25, you can change this with
          `--withdrawal-amount`) sitting in your account at all times,
          even when all orders have been filled because it's not always possible to
          fill all orders and there may be small rounding errors (on the order of cents)
        - It makes a best effort with minimal complexity to use all of your fiat,
          but it may not be possible to fill all orders right away
        - It may take a few days for the market to drop enough for the buys to fill
        - If the market experiences a significant bull run, your orders won't be
          filled, but it will reset every 24h (using the default buy timer)
