This page of the guide to the FUT 22 mode in FIFA 22explains when it's best to buy and sell player cards on the transfer market.
The card prices in the FIFA 22 Ultimate Team transfer market change dynamically depend on many factors. What's important, card prices for the same players vary by platform (PlayStation, Xbox, PC). However, you can wait for the right time to buy them much cheaper or put them up for sale at the right time for a big profit.
When to buy?
There are several times during the week when you should be browsing the transfer market for your dream players. The first such opportunity comes on Sunday, when players collect their prizes won in the Squad Battles mode. Many of them will get some good or even very good players, and the market may be flooded with new cards that may be underpriced by more sellers who will want to get rid of unnecessary cards quickly.
The next opportunity comes on the Sunday to Monday night, when the FUT Champions weekend league comes to an end and all participants claim their rewards. Throughout the week, Players look to have the strongest possible lineup for the weekend, but not all of their investments turn out to be accurate. Some players may not perform well in their setup or tactics, or they may have simply been used solely to achieve maximum lineup. As soon as the FUT Champions are over, many Players can put unwanted players up for sale to gain coins to buy other players for next weekend.
Starting Tuesday, the market situation begins to stabilize, and card prices may increase slightly until Thursday. On this day players collect rewards for the Division Rivals mode and flood the transfer market with gold cards with their overall ratings ranging from 75 to 80. This is the best time to buy a few or more players that can be used to make the SBC.
When to sell?
The best time to sell good and very good players, wanted by many Players who play at a very high level, is on the night of Thursday to Friday (until the afternoon hours). This refers to players like Virgil van Dijk, Varane, Walker, Messi, Mbappe, Ronaldo, Neymar Jr., N'Golo Kante and Renato Sanches. Everyone interested in FUT Champions will want to polish their lineups for the upcoming weekend league and will be willing to spend a lot on the FUT transfer market.
