When the page prompted with "API Key existed", it is probably because the API Key you have entered has already connected to ATPBot Before.
- Each ATPBot account can connect to multiple API Keys.
- You can connect both your Binance Spot and Margin account through one API Key.
- Each API key can only connect to one ATPBot account once at the same time.
You can check and manage your linked API Key in the "Exchange" menu in the "Dashboard".
