Method Detail

getOpenOrders

public OpenOrders getOpenOrders()
                         throws IOException

The additional data map of an order will be populated with RippleExchange.DATA_BASE_COUNTERPARTY if the base currency is not XRP, similarly if the counter currency is not XRP then RippleExchange.DATA_COUNTER_COUNTERPARTY will be populated.

Specified by:

getOpenOrders in interface TradeService

Returns:

the open orders, null if some sort of error occurred. Implementers should log the error.

Throws:

IOException - - Indication that a networking error occurred while fetching JSON data

getOpenOrders

public OpenOrders getOpenOrders(OpenOrdersParams params)
                         throws IOException

Description copied from interface: TradeService

Gets the open orders

Specified by:

getOpenOrders in interface TradeService

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 TradeService.createOpenOrdersParams().

Returns:

the open orders, null if some sort of error occurred. Implementers should log the error.

Throws:

IOException - - Indication that a networking error occurred while fetching JSON data

placeLimitOrder

public String placeLimitOrder(LimitOrder order)
                       throws IOException

order - this should be a RippleLimitOrder object with the base and counter counterparties populated for any currency other than XRP.

cancelOrder

public boolean cancelOrder(String orderId)
                    throws IOException

Description copied from interface: TradeService

cancels order with matching orderId (conveniance method, typical just delegate to cancelOrder(CancelOrderByIdParams))

Specified by:

cancelOrder in interface TradeService

true if order was successfully cancelled, false otherwise.

IOException - - Indication that a networking error occurred while fetching JSON data

cancelOrder

public boolean cancelOrder(CancelOrderParams orderParams)
                    throws IOException

getTradeHistory

public UserTrades getTradeHistory(TradeHistoryParams params)
                           throws IOException

Ripple trade history is a request intensive process. The REST API does not provide a simple single trade history query. Trades are retrieved by querying account notifications and for those of type order details of the hash are then queried. These order detail queries could be order entry, cancel or execution, it is not possible to tell from the notification. Therefore if an account is entering many orders but executing few of them, this trade history query will result in many API calls without returning any trade history. In order to reduce the time and resources used in these repeated calls In order to reduce the number of API calls a number of different methods can be used:

• RippleTradeHistoryHashLimit set the to the last known trade, this query will then terminate once it has been found.
• RippleTradeHistoryCount set the to restrict the number of trades to return, the default is RippleTradeHistoryCount.DEFAULT_TRADE_COUNT_LIMIT.
• RippleTradeHistoryCount set the to restrict the number of API calls that will be made during a single trade history query, the default is RippleTradeHistoryCount.DEFAULT_API_CALL_COUNT.
• TradeHistoryParamsTimeSpan set the TradeHistoryParamsTimeSpan.setStartTime(java.util.Date) to limit the number of trades searched for to those done since the given start time. TradeHistoryParamsTimeSpan

Specified by:

getTradeHistory in interface TradeService

Parameters:

params - Can optionally implement , , , , TradeHistoryParamPaging, , TradeHistoryParamsTimeSpan. All other TradeHistoryParams types will be ignored.

Returns:

UserTrades as returned by the exchange API

Throws:

IOException - - Indication that a networking error occurred while fetching JSON data
