Crypto Seller, I am going into finance, and I want only your strongest tokens.

Automatic Crypto Seller

This program is a wrapper around fin_depo for automatically trading one-way trades, by using repeated trades over a period. Can be used to slowly enter or exit positions, for example low-volume crypto currencies, or as an automated investment savings system.

Supported sites:

• KuCoin: Online crypto-currency exchange.

Installation

Install dependencies:

pip install -r requirements.txt

Usage

1. Create configuration file. See below and in examples/ folder for inspiration.
2. Create KuCoin API key with General and Spot Trading permissions.
3. Add KuCoin API key secrets (KUCOIN_KEY, KUCOIN_SECRET, KUCOIN_PASS) to an secret_loader accessible location .
4. Run script using python -m crypto_seller --config CONFIG_FILE.

The script will now automatically sell assets over time. The interval between sell-offs are randomized to avoid front-running, and the amounts are also randomized to avoid certain attacks (only relevant for smallish intervals of less than a week).

The log will both be displayed in the shell, and be placed in a log file output/log.txt. Every sell-off will be logged to the output/trades.csv file, with as much information as possible. Keep both of these for tax purposes, if relevant.

Configuration

Example configurations can be found in the examples/ folder.

Configurations are .json files, with the following fields:

{
    "input_asset": str,
    "output_asset": str,
    "input_amount_low": float,
    "input_amount_high": float,
    "interval_minutes_low": int,
    "interval_minutes_high": int
}

While input_amount_low and input_amount_high can be identical (and the same for interval_minutes_XX) it is discouraged, to avoid frontrunning attacks.

Auditing information

As mentioned before, this program is mostly glue code and wrappering around library functionality. The glue application code allows for running the main loop of checking balance, selling amount and sleeping until the next iteration, with some argument and configuration parsing thrown in.

The most relevant libraries for auditing are:

• fin_depo: Library for programmatic fetching of depository assets and in some cases allows for order placement. This is the library that reads balances and places market orders.
• fin_defs: Definitions of financial assets and instruments. Used by fin_depo.
• secret_loader: Library for loading of secrets (passwords, API keys, secret keys, configuration files, etc.) from standardized locations.
• python-kucoin: Used by fin_depo to provide KuCoin backend.

Taxation

Some parts of the world suffers from weird and draconian taxation rules on cryptocurrencies, so it helps to keep track of the relevant trading information.

As mentioned above, keep (and backup) both the log file (output/log.txt) and the trades file (output/trades.csv).

To help with tax reporting, it might be useful to sign up to tax oriented websites. For example, CryptoSkat seems to be the most mature on the danish market, and does support KuCoin.

TODO

• Allow multiple secrets configs
• Allow multiple output directories
• Fix TimeoutError issue occuring from slow Kucoin endpoint. Might require implementing own kucoin backend in fin_depo.
• Ensure that a failure during selling results in a safe winding down of the system.
  • Catch runtime errors when selling
  • Show status
  • Show errors to log.
  • Stop loop and exit with results, and error indicator.
• Present an overview of what the script will be doing
  • Sell what for what? How much, how often?
  • Give an estimate of how long it will take.
  • Wait 20 seconds before starting, to allow the user to review.
• Document command-line arguments
• Document configuration
• Document code auditing
• Parse configuration from json.
• Ensure sell time is included in order details
• Log all trades to CSV file.
• Collect information during the run and output after run

Dependencies

All requirements can be installed easily using:
