  • Separated the API and Website web socket sessions. WebSockets which were connected via the API will no longer be closed when the user logs out of the VALR website.
  • When a `PING` message is received on the Trade WebSocket, a response with `NO_SUBSCRIPTIONS` in the `PONG` will be sent, if the user has not subscribed to any message types.
  • When a user connects and authenticates to the Account WebSocket, all account balances and open orders associated with the user account will be sent in the response. One `BALANCE_UPDATE` message for each asset held and one `OPEN_ORDERS_UPDATE` message containing all open orders on the account, across all order books will be sent.
  • The `BALANCE_UPDATE` web socket message now includes an `updatedAt` field.
  • The REST GET Balances response (`https://api.valr.com/v1/account/balances`) now includes an `updatedAt` field for each asset held.
  • Added the REST GET VALR Status (`https://api.valr.com/v1/public/status`) request which will indicate whether the API is "online" or in "read-only" mode. In "read-only" mode, only GET and OPTIONS requests are accepted. The "read-only" mode is sometimes necessary during maintenance.
  • The `filledPercentage` field on open orders is now accurate to two decimal places.
  • The REST GET Order Book (`https://api.valr.com/v1/marketdata/:currencyPair/orderbook`) response and the REST GET Order Book (Non aggregated) (`https://api.valr.com/v1/marketdata/:currencyPair/orderbook/full`) response now include a `LastChange` field, indicating the timestamp of the last update to the order book.
  • The `AGGREGATED_ORDERBOOK_UPDATE` message on the Trade web socket now includes a `LastChange` field, indicating the timestamp of the last update to the order book.
