Enhance stop orders table view to handle the position linked stop order

[JonRay15]

The Chore

Since it is now possible to have a stop order that will close x% of your position we need a way to show this in the stop order table.

I would think something simple like as the size just show x% of position instead of the actual size?

Acceptance Criteria

• [ ] For stop orders where the size if given as a fraction of the position
  • [ ] Show the size as the percentage of the position
