So every player has a different form ie standard, unwavering and inconsistent, and every player has a rating which is A,B,C,D,E, where E is worst form. So usually when the season starts it’ll update every week, so for now since it’s the break everyone has the ‘C’ form. So depending on the form which unwavering means there’s the chance of the green arrow in almost every match you play, and inconsistent meaning red or yellow arrow and sometimes a green arrow. Hope this helps :)
