Just a little curious

Hey guys! I saw this cast of NAIDL and I was wondering what the little green/red arrows next to each name meant. Like next to Meghna, Varun, Yash and Tarun there are the green arrows pointing up whereas next to Simmi and Vaish's names there are red arrows pointing down. And then next to Kapil's name there is the yellow arrow pointing into directions. Could anybody explain to me what these are for? Just curious...thanks for your help! xoxoxo

its ranking of the stars on the whole (tv actors)...they will be updating these ranks every week...red mark indicates that tha actors rank has decreased this week compared to last week...green mark indicates it is increased compared to last week...yellow indicates that actor got the same rank of the last week
