Krypto-trading-bot, also called K, is a self-hosted automated trading bot written in C++. Its main purpose is market making: the bot continuously places both buy and sell orders on a cryptocurrency exchange, sitting on both sides of the order book at once and collecting the small price difference between them as profit. Because it is written in C++, it can place or cancel orders in under a few milliseconds on a typical machine, which is relevant for this style of trading where speed matters. The bot runs on Unix-like operating systems, such as Debian, Red Hat, CentOS, Raspberry Pi OS, and macOS. It stores data locally through a built-in SQLite database and connects directly to exchanges using standard network libraries, so no cloud service or Docker setup is required. The authors recommend a dedicated machine rather than a shared one. Several exchange connections are supported. The ones described as actively maintained include Coinbase, Binance, and BitMEX. Others such as Kraken, KuCoin, Bitfinex, Gate.io, HitBTC, and Poloniex are listed as under development or abandoned. Spot trading is supported across these, margin trading is listed as none. The project ships a few distinct programs. The main one, K-trading-bot, includes a full web interface for configuring and monitoring the high-frequency trading engine. A second program, K-+portfolios, shows account balances from an exchange and lets the user place or cancel orders manually. A minimal command-line tool called K-hello-world simply prints the current price of a given currency pair. This is a technical project aimed at people comfortable building and running software on their own servers. The README includes warnings about private key security when using decentralized finance platforms as an alternative to running the bot directly.
