Any of you that posted on here last season will be familar with these two sites and as per last season we had a thread to give people a head's up on rises and falls in prices for our main players.
For those of you not familar, when a player reaches 100% his price will go up (about 03:00 that night) or if he reaches -100% his price drops by .1
A player can only rise .3 or drop .3 in any gameweek.
Use these sites to your advantage, if you want rid of koscielny for example, but see he's not going to drop in price tonight, hang onto him incase one of your city players gets a serious injury tomorrow.
Likewise, use it to check if the player you want in, is going to rise.
The other thing, as i already mentioned is, prices don't change until 2 or 3 am that night, so there is absolutley no advantage (or sense) in making a transfer at 1pm or 6pm on a saturday.

Edit: Just including this link from JaxTeller in a different thread as it pretty much tells you everything you need to know about price changes
