The pricing system works based on relative performance. There are only two important factors to consider for the price, the match score of a player and their Performance Average.
The Performance Average is the rolling (unweighted) average score of a player in the last 30 games.
All players start their price at 50. The price then moves depending on how the player performs relative to their Performance Average. If they perform above the Performance Average in a given match, the price goes up, if they perform worse than their Performance Average in a given match, their price goes down.
The formula for the Price movement and the Performance Average calculation is below, with worked examples.
Price change factor:
This is the factor that is multiplied by the price at the end of the last match, to calculate what the new price should be.
Match Points:
Total number of points that a player is awarded for his contributions in a particular match
The price change factor is calculated in two parts, the price differential and then the price change factor.
Part 1
$$ Price differential= 1+0.14(Matchpoints-pref.ave/0.5*matchpoints+perf.ave) $$
Part2
$$ Price change factor= 0.005+(1/2-pricedifferential) $$
New Price:
It is the latest price of the player’s stock after the current match performance is considered
$$ Pricenew=Priceold*Price change factor $$
