While trying to historical test a strategy an order like this:

engine.submitOrder(getLable(instrument),instrument,ordCmd,0.1)


throws the following Exception:

The code used to submit an order works fine in my other strategies...

Could you please provide a full example strategy and a precise launch scenario (i.e. if the startegy is run in platform or standalone, with live data or in historical tester, if in historical tester - provide its settings).

The Strategy is run in standalone using historical tester.
Settings for historical tester:
       Date dateFrom = dateFormat.parse("03/01/2012 12:00:00");
       Date dateTo = dateFormat.parse("06/18/2012 00:00:00");

       
       client.setDataInterval(Period.DAILY, OfferSide.BID, InterpolationMethod.FOUR_TICKS, dateFrom.getTime(), dateTo.getTime());

You need to add in onStart:
engine = context.getEngine();
