Close position using OnExecutionUpdate()

[luislpez]

Hi,

I want to know how can I close a position when indicator do something. For example a SMA(5) cross SMA(34).

I know that I can do it using OnBarUpdate() method, but I am not sure how can I send a signal or something like that to exit using OnExecutionUpdate(). I just only did it with fixed targets and stop but not by a condition like a SMA crossing.

In this line of this sample shows a position entering and exit until reach a number of ticks:
stopOrder = ExitLongStopMarket(0, true, 1, execution.Price - 20 * TickSize, "stop", "long limit entry");
targetOrder = ExitLongLimit(0, true, 1, execution.Price + 40 * TickSize, "target", "long limit entry");

but what would happen if I want to close a position when indicator do something?

Hello luislpez,

Thanks for your post.

You could create a class level bool (initially set to false). In the OnBarUpdate section of your script, create a crossover condition that compares the SMA(5) to the SMA(34) and flip the bool to true. Then, you could check if the bool is true in the OnExecutionUpdate() section of your script and call your Exit methods to exit a position.

See the SampleMACrossover strategy that comes default with NinjaTrader for an example of creating a crossover condition comparing two SMAs. To view the script, open a New > NinjaScript Editor window, open the Strategies folder, and select the SampleMACrossover file.

Hi Brandon,

Could you please give me an example?. I tried using variables, public enum, but I think that the problem is that OnExecutionUpdate() only run one time when put a position, but when is running cannot call this method again to exit this position.

Hello luislpez,

Thanks for your note.

That is correct. The OnExecutionUpdate() method will only be called when an execution is placed such as an entry or exit order. This method will not get called for each bar update that occurs like in OnBarUpdate().

See this reference sample which demonstrates using OnExecutionUpdate() to submit orders: https://ninjatrader.com/support/help...and_onexec.htm
