Auction house flips on EU PvP Horde

A character can use its own faction's auction house and the neutral Blackwater house of its ruleset. When the same item is cheaper in one than in the other, you can buy it there and list it in the other. These are the gaps on World of Warcraft®: Forever that were also there a day ago, biggest first. Pick another house in the menu above.

Alliance against Horde

Moving goods between the factions needs a character on each side and a hand-off through Blackwater, where anyone can buy the listing before your other character does. So these gaps are harder to use, but they show how far apart the two factions' markets are.

How these are worked out

Prices are listed prices from the last hourly dump, not sales. A gap can close before you get there, and listing an item isn't selling it.
Buy and sell are near-lowest prices (the price of the cheapest 10% of units listed), so one stray cheap listing doesn't make a gap. Each side needs at least 20 units listed, to buy from and to sell against.
The gap is what a sale at the sell price brings in after the auction house's cut, minus the buy price. We haven't measured Forever's cut yet, so this assumes Classic's: 5% at a faction house and 15% at Blackwater. The deposit isn't counted. Only gaps from 10% to 200% after the cut are shown, at most 25 a table: a bigger gap is nearly always a few listings priced far above the market, which nobody buys.
A gap is shown only if it went the same way in the dumps about 24 hours earlier, so one that appeared this hour, and is probably gone soon, isn't.
Blizzard's data doesn't say which ruleset a house serves, so the names are inferred. They agree with BootyBayBroker's market labels and an in-game scan, but so far we've only confirmed EU PvP Alliance in game ourselves.
