Hi,

Could you please help me with the following error message I get mostly after starting the strategy (before putting in orders), sometimes a bit later (after putting in orders, with label "OVERNIGHT"):

java.lang.NullPointerException @ Strategy.on.onMessage(on.java:92)


This is the code:

90 public void onMessage(IMessage message) throws JFException {
91
92 if(message.getOrder().getLabel().startsWith("OVERNIGHT")) {
93 if (message.getType() == Type.ORDER_CLOSE_OK) {
94 if (message.getReasons().contains(IMessage.Reason.ORDER_CLOSED_BY_SL) ) {

Thanks in advance!

straightforwardly you can't process order if it is null, consider processing the IMessage in the following way:

   @Override
   public void onMessage(IMessage message) throws JFException {
      if (message.getOrder() == null) {
         return; // the message is not order-related
      }
      if (message.getOrder().getLabel().startsWith("OVERNIGHT") 
            && message.getType() == IMessage.Type.ORDER_CLOSE_OK
            && message.getReasons().contains(IMessage.Reason.ORDER_CLOSED_BY_SL)) {
         //your order-related logic comes here
      }
   }

Great, thanks for the fast help, it's working now.

Regards!
