    • restoreTrade

      Trade restoreTrade(String assetClass, String tradeProtocol, String restorationId) throws TradeException

      Creates a trade object to faciliate restoration of a trade with a client. Once the trade has been created, a restore event should be created via an invocation to Trade.createRestoreEvent(String).

      To allow for trades to be restored on the client, TradeEvent.setRestorationId(String) should be invoked on the first message sent to the client when it opens a trade. If the connection between the client and the Trading DataSource is lost and then re-established, the client will be able to identify the trade restoration message via the restorationId passed as an argument to this method.

      assetClass - The asset class of the trade, e.g FX or FI.
      tradeProtocol - The trade protocol. This must be the name of the state model.
      restorationId - The system identifier for the trade.
      The restored trade.
      TradeException - Thrown if the trade would be in an invalid state.
