Exitlong/short also opens an opposite position

[jlkramer16]

Hi I am having trouble using ExitLong() and ExitShort() methods.

Are there any cases which these could also open new positions? i.e. Position is long 1, ExitLong(Math.Min(Position.Quantity, X)) sells 2, making the strategy now short 1?

Thanks,
John

Hello John,

Thanks for your post.

Exit methods will not be able to open new positions. This behavior can be observed using a basic test script and the Simulated Data Feed. For Example:

protected override void OnBarUpdate()
{
	if(State == State.Historical) return; // Skip Historical processing
	
	// If we are flat, enter 2 long, otherwise exit 1 long position
	if(Position.MarketPosition == MarketPosition.Flat)
		EnterLong(2);
	else
		ExitLong(1);
}

Testing the code above you will see that on the first realtime bar closure, the strategy enters long 2, exits 1 on the next bar and exits the remaining quantity after that.

Further information on how the Managed Approach can be used for opening and closing positions, including the internal order handling behaviors can be found in the documentation page below.
