Exchange Documentation

Capandex is not affiliated with, endorsed by, or partnered with any cryptocurrency exchange. The platform uses publicly available exchange APIs to read market data and submit trade orders on behalf of users who have provided their own API credentials.

Your account on each exchange is governed by that exchange's terms of service, fee schedule, and policies. Capandex has no control over exchange operations, availability, fee changes, listing/delisting decisions, or any other exchange-level actions.

Users are responsible for maintaining their exchange accounts in good standing and for understanding the specific rules and limitations of each exchange they use.

Below are the exchanges currently supported by Capandex, along with links to their official API documentation and relevant resources. Users should review exchange documentation for details on rate limits, fee structures, and API key permissions.

When creating API keys for use with Capandex, follow these guidelines:

• Enable trade permissions only. Capandex requires read and trade access. Never enable withdrawal permissions.
• Use IP whitelisting where available. Some exchanges allow restricting API keys to specific IP addresses, adding an extra layer of security.
• Store passphrases securely. Exchanges like OKX, KuCoin, and Bitget require a passphrase in addition to the API key and secret. This passphrase must be entered when adding the key to Capandex.
• Rotate keys periodically. Regularly create new API keys and revoke old ones as a security practice.

For detailed step-by-step instructions on creating API keys for each exchange, see the Exchange Setup guide.

Each exchange has its own behaviors, rate limits, and quirks that may affect engine execution:

• Rate limits vary by exchange. Exchanges may temporarily block API access if too many requests are sent in a short period. Capandex respects exchange rate limits, but users running many engines simultaneously should be aware of cumulative request counts.
• Symbol naming conventions differ between exchanges. Capandex normalizes symbols to a common format (e.g., BTC/USDT), but some exchanges may have different tradable pairs or naming schemes.
• Minimum order sizes differ by exchange and trading pair. Ensure your position sizing nodes account for the minimum trade amount on your target exchange.
• Maintenance windows occur on all exchanges. During maintenance, API access may be disrupted. Running engines will resume on the next tick after connectivity is restored.
