With player prices in Fantasy Premier League susceptible to price changes on a daily basis, here is an explanation of how and why this occurs.
Why prices change
Player prices may change when they are heavily transferred in or out by FPL managers. A player's price can rise by £0.1m per day if they are a popular transfer in. However, if a player is heavily sold by FPL managers, their price can drop by £0.1m per day.
Historically they have tended to rise or fall by a total of £0.3m per Gameweek.
The change in a player's price will reflect their activity in the transfer market.
When prices change
Player price changes happen overnight UK time.
Impact of price changes
When a player has a price change, it can have an impact on FPL managers.
Managers can find themselves priced out of buying a player that they want. This can be because one of their players has decreased by £0.1m or because the player that they have been targeting has risen by £0.1m.
Over the course of the season, FPL managers try to grow their team value by investing in the players who are the most popular transfers in. This means that their team becomes worth more than the £100m that is given to FPL managers in pre-season.
However, the transfer market can also mean that managers' team value can slip under £100m, if their players are heavily transferred out.
Monitor transfers in and out
Managers should monitor the transfers in and out of players over the course of the season. This will allow managers to see who are the most popular transfers in, and therefore the players who are likely to rise in price. It will also show who's being heavily sold and is likely to fall in price.
When you're on your "Transfers" page, and can see the price tag for each of the players in your existing squad, the price you see is the amount you will get for SELLING the player.
That sale price may differ from the player's current PURCHASE price.
That's because you only get £0.1m of profit for every £0.2m that the player rises in cost.
For example, you could buy a player for £5.0m who then rises in price by £0.4m during the time that you own him.
Other managers will have to pay £5.4m to buy that player. But your selling price will be £5.2m.
But if you buy a player for £5.0m who then rises in price by £0.3m during the time that you own him, your selling price will be £5.1m.
And if you buy a player for £5.0m who then rises in price by £0.1m during the time that you own him, your selling price will be £5.0m.
