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. 

Yes but isn't the hourly updated, well, hourly. So if it's position was 8 the previous hour and it was 8 the next hour, why would it have a red arrow?

Each hour, they update the bestsellers list and the arrows reflect it position compared to 24 hours ago. So, an item can go on sale, shoot to number 1, then fall to number 5 2 hours later but it will still show a green arrow as long as it position is higher than it was 24 hours ago. So if the item was ranked 500th yesterday, it can fall from 1 to 99 over the course of 23 hours but will always show green. When the 24th hour passes, it will show red because a day prior,  it was number 1.

Ah, I get it now. Thanks for that.


:) No problem.
