Cancelling opposite orders, OCO style, in NinjaScript?

[RaygunWizzle]

Hi, I am trying to get it so that if either the target exit is filled or the stop is filled, it will cancel the opposite side pending order. This was how I attempted it at first:

protected override void OnExecutionUpdate(Execution execution, string executionId, double price, int quantity, MarketPosition marketPosition, string orderId, DateTime time)
{
if (execution.Order.OrderState == OrderState.Filled && execution.Order.Name == "longEntry")
{
ExitLongLimit(0, true, 1, (Close[0] + 20) , @"exitLong1", @"longEntry");
ExitLongStopMarket(0, true, 1, (Close[0] - 20) , @"longStop", @"longEntry");
}
else if (execution.Order.OrderState == OrderState.Filled && execution.Order.Name == "shortEntry")
{
ExitShortLimit(0, true, 1, (Close[0] - 20) , @"exitShort1", @"shortEntry");
ExitShortStopMarket(0, true, 1, (Close[0] + 20) , shortstop, @"shortEntry");
}

// if (execution.Order.OrderState == OrderState.Filled && execution.Order.Name == "exitLong1")
// {
// CancelOrder("longStop");
// }

// else if (execution.Order.OrderState == OrderState.Filled && execution.Order.Name == "longStop")
// {
// CancelOrder("exitLong1");
// }

// if (execution.Order.OrderState == OrderState.Filled && execution.Order.Name == "exitShort1")
// {
// CancelOrder("shortStop");
// }

// else if (execution.Order.OrderState == OrderState.Filled && execution.Order.Name == "shortStop")
// {
// CancelOrder("exitShort1");
// }

}

But I get the error "Argument 1: cannot convert from 'string' to 'NinjaTrader.Cbi.Order'" when trying to compile. I commented it out for now just so I could get everything to compile.
How can I accomplish this?

Hello RaygunWizzle,

Thanks for your post.

To clarify, what is the exact line of code throwing the error message in the code you shared?

If the error is coming from the lines of code where you are calling CancelOrder() this is because you are passing in a string value into CancelOrder() when an Order object is required to be passed in.

CancelOrder(Order order)

See the help guide documentation and reference sample below for more information about CancelOrder().

Yes, it was that. I was able to get it working with the following modifications.

private Dictionary<string, Order> orders = new Dictionary<string, Order>();


protected override void OnExecutionUpdate(Execution execution, string executionId, double price, int quantity, MarketPosition marketPosition, string orderId, DateTime time)
{
if (execution.Order.OrderState == OrderState.Filled)
{
string orderName = execution.Order.Name;

if (orderName == "longEntry")
{
ExitLongLimit(0, true, 1, (Close[0] + 20) , @"exitLong1", @"longEntry");
ExitLongStopMarket(0, true, 1, (Close[0] - 20) , @"longStop", @"longEntry");
}
else if (orderName == "shortEntry")
{
ExitShortLimit(0, true, 1, (Close[0] - 20) , @"exitShort1", @"shortEntry");
ExitShortStopMarket(0, true, 1, (Close[0] + 20) , shortstop, @"shortEntry");
}
else if (orderName == "exitLong1")
{
CancelOrder("longStop");
}
else if (orderName == "longStop")
{
CancelOrder("exitLong1");
}

else if (orderName == "exitShort1")
{
CancelOrder("shortStop");
}
else if (orderName == "shortStop")
{
CancelOrder("exitShort1");
}

orders.Remove(orderName);
}
}

Just for anyone else who researches this topic.
