Cost basis is determined by the fair market value of the coin or fiat currency being paid at the moment of the transaction.
For pricing, Lumina uses CryptoCompare for:
- Real Time Pricing Source: used to compute near real time aggregate portfolio values.
- Transaction Pricing Source: used for cost basis and proceeds computation at the time of transaction.
- Transaction Fallback Pricing Source: used for cost basis and proceeds computation at the time of transaction when the transaction pricing source doesn’t have pricing data for a specific asset. For example, if Lumina doesn’t have pricing data for an altcoin-to-altcoin transaction at an OTC venue, the system will fallback to the specified pricing provider.
- Crypto Fiat Pricing Source: if the BTC-to-Fiat trading pair or ETH-to-Fiat trading pair is not available at the trading venue, the system will fallback to the specified pricing provider.
The Reporting Pricing Source used for reconciliation reports can be from either CryptoCompare or CoinMarketCap. This setting can be changed by an Admin in Portfolio Settings.
