Constrain to local axis

I am new to blender. I have searched and cannot find an answer to this question hopefully its not too rudimentary. How do I constrain a scale of edge-loops to a local axis? In the image below I have the 2 sets of edge loops that I want to scale together. I tried constraining by x and y but that didn’t work.

Thanks in advance!

Are you looking to move both sets of edge loops at the same time? Or just one set at a time?

Split the object down the middle. Delete half and then use the mirror modifier. Select the 2 edges and set the transform orientation to normal. Now you can scale both along the axis of that wall.
