Cable Current Flow Direction

LOL...sometimes they will use an odd number of letters in their cable model nomenclature to indicate current flow....or was it even.....hmmm....I'm sure it will sound better if I could just remember the direction. Come on folks, really? Has this hobby come to this?

just to complicate things, w/some cable manufacturers, directionality refers to where the shielding is connected, if at all.

If the cable contains multiple conductors (signal & ground) and a shield, the shield is connected to ground on the sending end only. On the receiving end, shield remains open with no connection. Arrows will point in the direction of signal flow toward the receiving component.

With coax type cable, I have no idea why there would be any directionally,
other than “audio fashion.” Company ABC adds arrows to their cables
because Company XYZ has them.

I doubt that I could actually ever hear the difference. I have some cables with a small band or label at one end. Is there a general industry standard as to whether the banded end is the source or the destination? Or, does it vary according to supplier, as some responders have suggested?
(I do have some "arrowed" cables and the supplier of these told me that the arrow indicates the direction of the flow. They also told me that at one end the sheild is grounded, but not at the other end.)
In all cases, I am talking about RCA cables rather than XLR.
Thanks again!
