Connecting a trading bot to an exchange usually means creating an API key, and that key is the most sensitive part of the whole setup. If it is misconfigured, a compromised bot or a leaked key can trade your funds, even if nobody can withdraw them directly. Good API security is not complicated, but it requires care at the moment you create the key, because that is when permissions are set. Taking ten minutes to configure a key correctly is far cheaper than recovering from a key that was given too much power.

The single most important rule is to disable withdrawal permission on any API key used by a bot. A trading bot needs permission to place and cancel orders and to read your balance and positions. It does not need permission to withdraw funds. If a platform asks for withdrawal access for a trading bot, treat that as a warning sign and look for another option. Also avoid giving a bot permission to transfer funds between accounts unless you have a specific reason and understand the risk. After creating the key, double-check the permissions screen before pasting the key anywhere, because a single missed checkbox can undo all other precautions.

Where your exchange supports it, restrict the API key to specific IP addresses, such as your server or your bot provider's addresses. This means a leaked key is far less useful to someone operating from elsewhere. Enable two-factor authentication on your exchange account itself, and use a strong, unique password stored in a password manager. Remember that API keys bypass normal login protections in some respects, so account security alone is not enough. If you run a bot on a personal computer, consider whether that machine is secure enough to hold a key, and prefer a dedicated setup or a reputable hosted bot service over a shared or public computer.

Never paste an API key into a public chat, a shared document, a screenshot, or a code repository. Store keys in the bot platform's secure settings or in an environment file that is not shared, and avoid emailing them to yourself. Rotate keys periodically, for example every few months, and immediately after any suspected exposure, such as sharing your screen during a support call or using an unfamiliar device. Rotation is simple on most exchanges: create a new key, update the bot, test it with a small trade or a read-only check, then delete the old key. If you find an old key you no longer recognise, delete it rather than leaving it active just in case.

After connecting a bot, monitor its activity for the first days, not just its profits. Check that order sizes match your settings, that it trades only the pairs you approved, and that it stops when it should. Set up exchange alerts for logins, new API keys, and large orders where available. Also prepare a kill plan: know how to disable the API key instantly from your phone or computer, and how to cancel all open orders. Practice finding those controls before you need them under stress. A bot that trades well is useful, but a bot you can stop instantly is safe, and safety has to come first. Review your active API keys monthly, delete any you no longer use, and treat every new connection as a security decision, not just a setup step. If a provider is breached, assume your key may be exposed and rotate it immediately.
