Order rejected on live trading strategy

[matrixxx]

Case 1:
The order terminated itself, I'm no idea.

Submitted an order that generated the following error 'Order rejected'. Strategy has sent cancel requests, attempted to close the position and terminated itself.

Case 2:
When the strategy should submit the ExitLongLimit() to exit the current position but no signal show on the platform. How can i know the strategy had submit the request to the broker or not?

ExitLongLimit(1, true, entryOrder.Quantity, Open[0], LIMIT, OPEN_LONG);

Hello matrixxx,
Thanks for your post.

We would need to see the reason given by the platform for the order rejection. You will likely find it in the immediate vicinity of the message you posted.

In regards to "case 2":

Does the strategy show an error when it is supposed to submit its exit order?

Do you see that the order was submitted on the 'Orders' tab of your Control Center?

Hi JoshG,

Case 2, No order submitted on the order tab.

[NinjaTrader_JoshG]

Have you confirmed (with Print statements) that your conditions are becoming true to submit the ExitLongLimit order?

Hi JoshG,


The conditions is true and printed the time before submit the order function but no order and no error show on the platform. I'm using Ninjatrader FXCM trial account.

protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice, int quantity, int filled, double averageFillPrice, OrderState orderState, DateTime time, ErrorCode error, string nativeError)
{

if (order.Name == OPEN_LONG || order.Name == OPEN_SHORT)
{

entryOrder = order;

}
else
{

if (order.OrderState == OrderState.Filled)
{

entryOrder = null;

}

}

if (entryOrder != null && entryOrder == order)
{

if (order.OrderState == OrderState.Filled)
{

if (order.Name == OPEN_LONG)
{

Print("=========================================== ===");
Print("");
Print(Time[0]);
Print("ExitLongStopMarket()");
Print("");

ExitLongStopMarket(1, true, quantity, Low[0], STOP, OPEN_LONG);

}

}
else if (order.OrderState == OrderState.Cancelled)
{

entryOrder = null;

}

}

}

Is it different if i use the demo account to execute the strategy like live account?
Is it use same api to process the order?


After add some code to get the reference to the stop order and add more print log.

protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice, int quantity, int filled, double averageFillPrice, OrderState orderState, DateTime time, ErrorCode error, string nativeError)
{

if (order.Name == OPEN_LONG || order.Name == OPEN_SHORT)
{

entryOrder = order;

}
else
{

if (order.OrderState == OrderState.Filled)
{

entryOrder = null;

}

}

if (entryOrder != null && entryOrder == order)
{

if (order.OrderState == OrderState.Filled)
{

if (order.Name == OPEN_LONG)
{

Print("=========================================== ===");
Print("");
Print(Time[0]);
Print("ExitLongStopMarket()");
Print("");

Order stopOrder = ExitLongStopMarket(1, true, quantity, Low[0], STOP, OPEN_LONG);

Print("StopOrder: " + Time[0]);
Print("stopOrder.OrderId: " + stopOrder.OrderId);
Print("stopOrder.Name: " + stopOrder.Name);
Print("stopOrder.OrderType: " + stopOrder.OrderType);
Print("stopOrder.OrderState: " + stopOrder.OrderState);
Print("");

}

}
else if (order.OrderState == OrderState.Cancelled)
{

entryOrder = null;

}

}

}

I got the following error.

Error on calling 'OnOrderUpdate' method on bar 3552: Object reference not set to an instance of an object.

The platform didn't throw the order submit fail if i didn't add the "Order stopOrder = ExitLongStopMarket()" to get the object reference to throw the error. I'm using 1 min time frame.


Please advise. Thanks.

That error looks like the result of attempting to access an order object without checking to see if it is null first. You should always check if an object variable is null before attempting to access the object.

The following forum post goes into detail on checking for null references.

Running your strategy on the demo data feed will not impact your strategies logic or executions.

Dear JoshG,

My problem is why the submit order return null. The ExitLongStopMarket() not submit the order to broker and no submit log show on the platform.

I would like to set the stop loss when the long/short order filled.

Please advise.

My problem is why the order is null

The order variable is null because it has not been assigned an Order object yet. Thus when trying to access the object properties it fails and yields the “Object reference not set…” error since the variable is null. The order being null is not an issue. You just need to check for it to be null before accessing it.

The ExitLongStopMarket() does not submit the order

Your strategies orders are not submitting because of the object reference error.

I would like to set the stop loss when the long/short order is filled

We have a sample in our help guide that demonstrates how to implement this in your strategy.

Last year, I realized that there was some issue with Forex Limit orders, regardless was FXCM or another broker. It seemed that whenever you submitted a limit order ( with that fast quotes in 1/10 pips ) with a price a little off, the order was rejected. I've brought that issue up to NT support attention. I'm still not sure if this is cause Brokers only accept orders in HalfPips or cause a little mismatch with bid-ask prices triggers a bug. I'll be listening to the findings of support team.

I fixed the issue by move the exit order to OnExecutionUpdate.
