CancelOrder

[fiddy]

i have the below code in my strategy. it seems to be causing me to get the error msg.


"Error on calling 'OnBarUpdate' method for strategy 'ATH/a345ea62bae9432396d3110642471752': Object reference not set to an instance of an object."

is there something that i am missing below?
Do i need to include entryOrder = null within the OnBarUpdate below CancelOrder(entryOrder) rather than OnOrderUpdate section

if (Position.MarketPosition == MarketPosition.Flat
&& ToTime(Time[0]) > 42000
&& ToTime(Time[0]) <= 50000 )
{
CancelOrder(entryOrder);
}


protected override void OnOrderUpdate(IOrder order)
{
if (entryOrder != null && entryOrder == order)
{

if (order.OrderState == OrderState.Filled || order.OrderState == OrderState.Cancelled)
entryOrder = null;
}
}

Hello fiddy,

Thank you for writing in.

You'll want to make sure that entryOrder is not null before trying to cancel it.

I would suggest taking a look at this link on our support forum for more information about null checking: http://ninjatrader.com/support/forum...ead.php?t=4226

Please, let us know if we may be of further assistance.
