What are the side effects of manually using "Close" while a strategy is running?

[DogEars]

Hi,

If I have a strategy running that is trading autonomously and I manually flatten my position what happens under the hood with my strategy? I know it continues to run, but the execution isn't firing now when it should.

Just curious what really happens underneath and can I work around it programmatically?


Thanks.

Hello DogEars,

Thanks for your question.

Hitting the Close button to close a position on an instrument in which a strategy is running will close the position and disable the strategy.

Strategies are intended to operate on their own positions which are separate from the actual account position. This would mean that the strategy is intended to stay in sync with the account, and manual order submissions will desync the strategy from the account.

However, strategies can be built to manage manual entries in a couple ways:

1. Using AdoptAccountPosition to capture the account position and have the strategy manage that adopted position
2. Writing a strategy that uses the Unmanaged Approach, and keeps track of the Account Position with PositionAccount

Hi DogEars,

That is a nice strong reply from Jim.


To extend on Jim's reply ...


If you want to "have your cake and eat it too" ....

Strategies will keep running if it is the Strategy rather than buttons in the ChartTrader UI that initiate the Close or Flatten.

Here in this forum and in the NT ecosystem free app share there are a number of examples of Indicators using on-Chart buttons.

I think you could create an indicator that is called by and used by the strategy that hosts two buttons that appear on the chart. One button titled Close and another titled Flatten.

Click on one of those puppies and your well thought out and tested strategy will shut that position and keep happily spinning along.

The first example is a good starting place to see the concepts play out.

The second is much more complicated but also, if you dig hard has code to leverage to either close or flatten in response to a click of the button. This core great but will ask you to bring pretty strong C# skills.

You can drive the buttons from a strategy or addon as well if you have C# skills.
