Computers have placed fast orders in markets for years.
What is a crypto trading bot for?
A bot places orders too fast for a person to react, and it can split a large order into smaller parts. Banks, funds and private traders use similar tools. The aim is speed, not a promised profit.
How does a crypto trading bot work?
A bot connects to an exchange through an API key you create in your settings. The key lets it read prices and send orders.
- An exchange API key or a wallet link
- Rules for entries, exits and stops
- Market data such as price and volume
- A computer or service to run it on
What are the main risks of bots?
Bots can lose money from a coding bug, an exchange outage, a stolen API key or a bad fill. Bot trades can be taxable: the IRS treats crypto as property, so trading one crypto for another usually is taxable, while buying with dollars is not. Keep records of every trade.
How is it different from copy trading?
A bot follows rules that you or a developer wrote, and it acts on its own. Copy trading and signal groups follow another person instead, by mirroring their trades into your account or leaving the choice to you.
