automated system failure

[Futures_Shark]

I have the following code in an automated system. It has been working fine and executing upon a fill in the primary contract. today it failed twice. Is there anyway to track down how or why this could have happened. BY fail i mean this code segment did not submit the order wehn there was a fill in the order specificed by the ZBOrder order



protected override void OnOrderUpdate(IOrder order)
{
if (ZBOrder != null && ZBOrder.Token == order.Token && order.OrderState == OrderState.Filled )
{

ZBWrk = true;
Print("***********************FILL**************** ********");
Print("QTY:"+order.Quantity.ToString());
if (sBuySell=="S")
{
//ZNOrder = EnterShortLimit(1,true,order.Quantity,GetCurrentBi d(1), "SPRD2");
ZNOrder = EnterShort(1,order.Quantity,"SPRD2");
Print("SELL ZN:" + (GetCurrentBid(1)));
}
if (sBuySell=="B")
{
//ZNOrder = EnterShortLimit(1,true,order.Quantity,GetCurrentBi d(1), "SPRD2");
ZNOrder = EnterLong(1,order.Quantity,"SPRD2");
Print("BUY ZN:" + (GetCurrentAsk(1)));
}


Print("***********************FILL**************** ********");
ZBOrder = null;
}
}

You might be running into an issue we have recently come across that is forcing us to adopt a new advised approach when it comes to triggering order submissions. Instead of OnOrderUpdate() we will advise and provide a reference sample with using OnExecution(). This should be out in the next few days and I suggest re-coding this aspect of your strategy and then letting us know if you see something unexpected again.
