[PS4] --> [H] Black Market Heatwave, keys; [W] Chakrams (black/cobalt/crimson)

Sale Price Outcome Example
0-75% Market Value Congratulations! You are selling an item for less than it is worth. Your post will be upvoted, and you will gain visibility to find a buyer easily. Heatwave 16 Keys
80-100% Market Value You may possibly find a buyer, but your vote counter will generally be left unharassed in this range. Saffron Photon 3 Keys
100-110% Market Value Now you are playing with fire. RLE generally does not tolerate market variance, despite some of the comments you may see around here. If you are even the tiniest bit off from Reddit's collectively unwritten prices, you will be downvoted immediately in the first 5 minutes of your post. Don't believe me? Go post a topic offering to sell White Discos for 9 keys, despite the fact 9 keys is completely within standard market variance, and despite the fact that some White Discos sell at 9 keys every day. Go ahead. I'll wait.
110% and above Market Value You will be downvoted multiple times. You might find a buyer, but you're probably one of those annoying users who posts the same topic every hour despite getting zero responses. Heatwave 20 Keys

Addendum #1: Examples are based on PS4 trading

Addendum #2: Please note that Market Value refers to the average sale price of an item across the entire Rocket League userbase on a given platform. The key takeway here is that average Market Value is higher on Reddit when compared to an overall platform userbase, or even when compared to other trading circles like Rocket League Garage or PlayStation Communities.

Addendum #3: An additional ~15% of all sale posts will be downvoted for no reason at all. I call this the standard RLE downvote modifier, or SDM for short.

Addendum #4: You can invert this chart if you are the buyer and not the seller, but the key ideas remain the same.
