When does my squad lock and when do points appear?

A fantasy round is one calendar week, and it locks at the kickoff of the first league game of that week. Until that moment you can change your squad freely. After the last game of the week is finished and its result is recorded, the round is scored and you get a notification with your points and your place. Matches moved to another day count in the week they were actually played, so a postponed game is scored in its real week.
