I work with Price Engine API and send a DataMakerRequest with a FXCMTimingIntervalFactory.toCode(1), but the server response the follow exception message:

[WARN] [ com.fxcm.messaging.util.CommunicationException ] socket closedcom.fxcm.messaging.util.CommunicationExcepti on: socket closed

I don't know why, please can you help me?

Can you confirm that you are properly logged in? Can you pull up a tradingsessionid. And can you show us the code you are using to build and submit the marketdatarequest

I'm loggin with user=test1, password=password1, but I prepared a Property object:

Properties properties = new Properties();
properties.setProperty("ProxyServer", "127.0.0.1");
properties.setProperty("ProxyPort", "8008");
properties.setProperty("ProxyUserID", "test1");
properties.setProperty("ProxyPassword", "password1");

ConnectionManagerEx.init(properties);

This is my MarketDataRequest:
MarketDataRequest mdr = new MarketDataRequest();
mdr.setFXCMTimingInterval(interval);
mdr.setMDEntryTypeSet(mdEntry);
mdr.setSubscriptionRequestType(subscription);
mdr.setTradingSessionID(cUserSession.getTradingSes sion().getID());
mdr.setTradingSessionSubID(cUserSession.getTrading Session().getSubID());
mdr.setFXCMNoSnapshot(0);

mdr.setMDReqID(cUserSession.getNextRequestID());

mdr.setFXCMStartTime(timeStart);
mdr.setFXCMStartDate(dateStart);
mdr.setFXCMEndTime(timeEnd);
mdr.setFXCMEndDate(dateEnd);

where:

interval = FXCMTimingIntervalFactory.toCode(1);
subscription = SubscriptionRequestTypeFactory.SNAPSHOT;
mdEntry = MarketDataRequest.MDENTRYTYPESET_ALL;

I used example.java with this values and the server response

[WARN] [ com.fxcm.messaging.util.CommunicationException ] socket closedcom.fxcm.messaging.util.CommunicationExcepti on: socket closed

at com.fxcm.messaging.util.pdas.communicator.Communic ator.run(Communicator.java:302)
at java.lang.Thread.run(Unknown Source)

I don't undertand because a try with
interval = FXCMTimingIntervalFactory.toCode(2);
interval = FXCMTimingIntervalFactory.toCode(3);
...

and not recived this message. Please help me
