# VST - Algorithms

### <mark style="color:purple;">-> B</mark><mark style="color:purple;">**uy/ Sell System**</mark>

We have implemented an algorithm calling “*Buy/ Sell system*” that is based on the demand and offer on the market. It’s a common system we can found on classic trading platform. This algorithm will therefore follow the market flow based on supply and demand. Thus, the price of a sportsmen increases if demand increases. It is inversely proportional when demand decreases.

For the sell part, VST implemented 2 different models:

* To list the shares in the selling queue to get someone buying it.

But what will happen if no one wants to buy shares? How can I get back my benefits?

* VST also offer the opportunity to sell you shares to the platform at any time to the market price.

This option will reinforce the trust of the customers to VST.

### <mark style="color:purple;">-> Performance Algorithm</mark>

Relying solely on buy/sell to see prices fluctuate makes the platform obsolete. How do you get a customer to buy shares? On what criteria will customers buy player shares? These questions allowed us to review the principle of trading in sport and thus improve it.

To make this service more attractive and inclusive, it is necessary to take into account the performance of sportsmen during matches. An algorithm based on several match events has been built to integrate a bonus or a malus on the price of the sportsmen after each match.

The calculation considers more than 70 attributes/criteria. Each attribute corresponds to an action performed by the athletes, e.g. "successful short pass", "goal", "successful tackle", etc. For each attribute, VST assigns a number of points, positive or negative. The final grade is calculated at the end of the match. This total is then converted into a percentage to be applied to the athlete share’s price.

### <mark style="color:purple;">-> Reward System</mark>

To make the platform more attractive, to build customer loyalty and to encourage the diversification of the wallet, we have introduced a “reward system”. This system is working like dividends on real market but it’s effective after each day of match. A top 3 of the best players of the day will be established, based on their performances during the game.

### <mark style="color:purple;">-> NFT Badges</mark>

Each NFT released is a representation of a player listed on the market. The number will be limited. They don’t represent a share of a player, but they are more like a “badge”. They will allow every owner to:

* Reduce fees when selling shares,
* Give access to a complete data offer,
* Increase the amount of the dividends.
