Need a little help with order filled code

[Jimmyk]

Hi, please excuse my lack of knowledge about coding matters.
I'm trying to insert this code into a strategy to email me when an order is filled.

protected override void OnExecution(IExecution execution)
{
if (execution.Order != null && execution.Order.OrderState == OrderState.Filled)
{
SendMail(@"[email protected]", @"NT8 Buy Action", @"Buy Order Placed");
}
}

However when I compile I receive the following error message.

The type or namespace name ='IExecution' could not be found (are you missing a using directive or an assembly reference?) CODE CS0246

Can anyone advise me of what stupid thing I'm doing here thanks heaps.
I found the code on another thread, so not sure if it works for NT8

Hello Jimmyk,

Thank you for the post.

This code is for NinjaTrader 7, OnExecution() has been changed to OnExecutionUpdate() in NinjaTrader 8.

In NinjaTrader 8, all order data can now be accessed in OnExecutionUpdate() instead of OnExecution().

Here is the equivalent function with the send mail statement.

protected override void OnExecutionUpdate(Execution execution, string executionId, double price, int quantity, MarketPosition marketPosition, string orderId, DateTime time){
    if(execution.Order != null && execution.Order.OrderState == OrderState.Filled){
        SendMail(@"[email protected]", @"NT8 Buy Action", @"Buy Order Placed");
    }
}

Below I have included publicly available links to the Execution class, OnExecutionUpdate(), SendMail(), and the code breaking changes for NinjaTrader 8.
