The Portfolio page gives you a complete look at your balances and trading activity across all connected exchanges. Check below to see if your exchange is compatible with the portfolio tool.
You can add exchanges to your Cryptowatch portfolio via the Exchange Keys page. You will need to generate an API key from your exchange account in order to connect to Cryptowatch. The process is nearly identical to connecting a trading-enabled exchange — the difference is which permissions you grant the API key.
The available permissions differ on each exchange. Portfolio-only exchanges must have "read" permission granted to the API key (basically, permission to see your account). Permissions to withdraw, deposit, create or cancel orders and more are not required for Portfolio-only exchanges.
