Suggestion : Extend Order Properties

[GrumpyTrader]

It would make sense to make position sizing an extension type in ninjascript and add it to the order properties. You can still have the strategy override type but it would be nice to have an extension type that could be utilized for any strategy.

Alternatively, you could add a OnPositionSize virtual method to StrategyBase that allows the user to calculate the position size when using managed orders like EnterLong() which don't specify a size.

Hello GrumpyTrader,


Thanks for the feedback.



Your suggestion has been submitted and accepted for consideration for a future NinjaTrader release by our product development team. I'll update this post with a tracking ID for this request when it is available

How is that different from Position.Quantity?

I'm suggesting you make the sizing logic an extension type so they can be extended and called without any added code to a specific strategy.

That way when back testing a strategy in the Strategy Analyzer under Order Properties you would be able to have (instead of just Default quantity, Account size and Strategy) you can have Fixed Risk, Percent Risk, etc.

Interesting idea.
