The PS4's had its red arrow for the whole day and pretty much remained at 8.

To clarify, the arrow color represents the product's current position relative to adjacent products when compared to 24 hours ago. Therefore, it doesn't give absolute direction of sales.
For example, the PS4 may be selling at the same exact rate as yesterday. It was the 5th highest selling product. But today the PSN cards, and Zelda sold more therfore even if PS4 SOLD the same amount today, it's rank fell compared to its rank yesterday.
And vise versa. Amazon Best Sellers don't show if something is selling more or less, only it's sales in comparison to other products.

I don't think theory is correct, though. There are times in the past 24 hrs when the arrows have been gone for an hour, only to return the next. And earlier, the XBO had a green arrow, yet fell a spot, while the PS4 has had a red arrow for hours, while the other products have had none or green, yet remained at #8. I don't think anyone has truly figured out how the Bestsellers truly works.
My guess, at least for the arrows, is they are comparing the sales of a product to its sales in the previous hour or so (I think the updates are actually for a few hours past.) So, a product may sell a couple of units short of its sales from the previous hour, while the product below it may sell a couple more, but it may not actually be enough for the lower product gain a spot. That's my theory, anyway.
