You can choose the price source for each cryptocurrency individually in Delta. By default, the app uses the Delta Global Average (DGA) if it is available; otherwise, it will default to one of the available exchanges.
To change the source of the price for a specific coin, you can follow these steps:
Open the specific asset's detail screen by tapping on it in your Portfolio, Watchlist, or the Markets tab.
Tap on the current price source (the exchange and trading pair) displayed just above the price chart.
Select your preferred exchange and trading pair to configure it as your new price source.
Important things to keep in mind regarding pricing sources:
Crypto Only: The ability to manually change the pricing source is strictly available for cryptocurrencies.
Portfolio vs. Watchlist flexibility: You can select different pricing sources for the exact same coin depending on where you are viewing it. For instance, you could set your Portfolio to track a coin using Coinbase Pro, while having your Watchlist track it using Binance.
Fiat Conversion: If you select a crypto-to-crypto trading pair as your source (for example, ETH/BTC on Binance), Delta will take that price and automatically convert it into your primary fiat currency (such as USD or EUR) using Delta's global average rates, so your total portfolio balance remains accurate.
