Position Sizing Question

[njmeyer713]

Hello All-

Please see the attached trade for reference.

I have built a strategy that will take trades of 2,4,6,8, etc contracts which the user can set as a input when enabling the strategy.

Then I want the strategy to sell half of the total contracts at a certain profit target and let the rest go as runners.

In the attached screenshot the strategy is set up to trade 2 contracts.

Question, if the strategy buys 1 contract and then another 1 contract to get a the full desired position size of two, does Ninjatrader count that as a position size of 2 when I use the following code to exit half the position, ExitLong(Position.Size / 2 )

Or does the Ninjatrader code treat these as two separate positions of 1 contract each?


Hopefully this question makes sense.

Thank you,

Nick

Hello njmeyer713,

Thanks for your post.

Position.Size would not be a valid argument to get the current position size. You would need to use Position.Quantity instead to get the current position size.

See the help guide pages below for more information about Position methods/properties and Position.Quantity.

Brandon,

Thank you for the response. So if I use the correct code with Position.Quantity, how will it calculate the quantity? As one position with 2 contracts or 2 different positions with 1 contract each?

Thank you,

Hello njmeyer713,

Thanks for your note.

Position.Quantity would refer to the total current position size seen in the Position column of the Strategies tab on the Control Center.

So if your strategy has placed a total quantity of 2 long orders, the Positions column in the Strategies tab on the Control Center would report 2 long and Position.Quantity would return 2.
