Exchange Rates

Exchange rates are the rates at which one currency can be exchanged for another.

Overview

Exchange rates are always quoted in pairs, where the first currency is called the base currency and the second is the quote currency. For example, in the pair USDEUR, USD is the base currency and EUR is the quote currency.

For each currency pair, two rates are provided:

  • Sell Rate: The rate at which you can sell the base currency in exchange for the quote currency.
  • Buy Rate: The rate at which you can buy the base currency using the quote currency.

Example

Given the following rate object:

Example GBPUSD Rate

{
    "ccyPair": "GBPUSD",
    "baseCcy": "GBP",
    "quoteCcy": "USD",
    "sellRate": 1.35259,
    "buyRate": 1.35303
},
  • Sell Rate: 1.35259 - means you can sell 1 GBP for 1.35259 USD.
  • Buy Rate: 1.35303 - means you can buy 1 GBP for 1.35303 USD.
