Just browsing through your proof I can tell that they're all unsolds. If you want to raise the price you have to show that 4 keys is able to sell, not just that people are willing to sell at a higher price and nobody buys them.

ok there are a few things wrong with your proof, although it is by no means terrible and better than most newbie suggestions

1) please label your proof! showing us a bunch of links isnt really helpful, organize them into sections and label them, eg selling for 4 keys (insert links) selling for >4keys (insert links)

2) unsolds are not a valid proof on their own, and are not enough to raise prices, to do so you'll need Sales (not selling!) at the new range your trying to prove (in your case, 4.33 keys)

3) most importantly selling =/= sold, this means you should not mistake people selling at a higher value for a needed price change, i could get me and my friends to try to sell a gibus at 20 buds, this dosnt mean the gibus is suddenly worth 20 buds just caus 10 people decided to price their trades like that! however if for whatever reason all 10 of them sold for 20 buds legitimately, then you could price it at 20 buds.

tl:dr get sales first, then add unsolds and selling to flesh out your proof a bit more

Hope this was useful!
