Progressive User Ranking System

[swamy_g]

Hi all,

I'm working on this website that lets you predict which stocks (the ones trading in the stockmarket like NYSE/NASDAQ) are going to rise and fall. Its very similar to socialpicks.com or feelingbullish.com. The main core of the site is the ranking algorithm. If suppose User A ranks Stock 1 as BUY (he can rank it as BUY/SELL/HOLD) and if the next day the Price is higher than its previous day, then he has predicted it right so the next time his Input must be weighed higher than others. On the other hand if his prediction goes wrong his rank should be reduced. The next time he votes His/her prediction gets a bigger wieghtage because of his previous experience

 

I've done a small working example here Please take a look at it

Now How should i rank the USER if his prediction comes true, Please help me out, i'm not satisfied with the ranking i've used in the above system

Thanks a lot
