public interface TradeService extends BaseService
Interface to provide the following to Exchange:
  • Retrieve the user's open orders on the exchange
  • Cancel user's open orders on the exchange
  • Place market orders on the exchange
  • Place limit orders on the exchange
  • Change limit orders on the exchange

The implementation of this service is expected to be based on a client polling mechanism of some kind

      Gets the open orders
      Parameters:
      params - The parameters describing the filter. Note that OpenOrdersParams is an empty interface. Exchanges should implement its own params object. Params should be create with createOpenOrdersParams().
      Returns:
      the open orders, null if some sort of error occurred. Implementers should log the error.
      Throws:

    • getTradeHistory

      default UserTrades getTradeHistory(TradeHistoryParams params) throws IOException
      Fetch the history of user trades.

      If you are calling this method for single exchange, known at the development time, you may pass an object of specific *TradeHistoryParam class that is nested it that exchange's trade service.

      If, however, you are fetching user trade history from many exchanges using the same code, you will find useful to create the parameter object with createTradeHistoryParams() and check which parameters are required or supported using instanceof operator. See subinterfaces of TradeHistoryParams. Note that whether an interface is required or supported will vary from exchange to exchange and it's described only through the javadoc.

      There is also implementation of all the common interfaces, TradeHistoryParamsAll , that, with all properties set non-null, should work with any exchange.

      Some exchanges allow extra parameters, not covered by any common interface. To access them, you will have to use the object returned by createTradeHistoryParams() and cast it to the exchange-specific type.

      Parameters:
      params - The parameters describing the filter. Note that TradeHistoryParams is an empty interface. Exact set of interfaces that are required or supported by this method is described by the type of object returned from createTradeHistoryParams() and the javadoc of the method.
      Returns:
      UserTrades as returned by the exchange API
      Throws:
      ExchangeException - - Indication that the exchange reported some kind of error with the request or response
      NotAvailableFromExchangeException - - Indication that the exchange does not support the requested function or data
      NotYetImplementedForExchangeException - - Indication that the exchange supports the requested function or data, but it has not yet been implemented
      IOException - - Indication that a networking error occurred while fetching JSON data
      See Also:

    • createTradeHistoryParams

      default TradeHistoryParams createTradeHistoryParams()
      Create TradeHistoryParams object specific to this exchange. Object created by this method may be used to discover supported and required getTradeHistory(TradeHistoryParams) parameters and should be passed only to the method in the same class as the createTradeHistoryParams that created the object.

    • createOpenOrdersParams

      default OpenOrdersParams createOpenOrdersParams()
      Create OpenOrdersParams object specific to this exchange. Object created by this method may be used to discover supported and required getOpenOrders(OpenOrdersParams) parameters and should be passed only to the method in the same class as the createOpenOrdersParams that created the object.

    • verifyOrder

      default void verifyOrder(MarketOrder marketOrder)
      Verify the order against the exchange meta data. Most implementations will require that Exchange.remoteInit() be called before this method
