Why-doesn-t-the-fixed-value-position-size-change-the-position-size-with-the-price-of-contract

Hello,

I have noticed that when I set a fixed value for the position size, it always purchases the same amount of contracts throughout the history of the backtest. I was expecting it to adjust the number of contracts purchased with a "fixed value". As it stands, this setting acts exactly the same as setting the position size for number of contracts.

Is there a setting for what I am looking for? Is this behaving as designed? Note: This is using futures contracts.

Below are screenshots of my settings and the position sizes I am getting.

Thanks,
Dandude
