in real time systems, buyers and sellers post request for trading, details are { company, shares, price, action(buy/sell) }
- vikas June 13, 2014A centralized system has to keep track for price, if price is met, it looks for prospective buyers and sellers ( note at every price change , a publisher-subscriber) ,
When I say prospective, it means system need to check if a sell request can be fulfilled with 1, 2 or more buyers and viceversa. ( this can be implemented using hashmap to be real time )
so overall, design can be
class Market implements Observable{
// check for price change here per company shares
}
class Company implements Observer{
// implement common company code
// use strategy to make custom company logic if any
}
Singleton class CombineSellers{
// custom logic to get combinedSellers for some buy request at one time
}
Singletom class CombineBuyers{
// viceversa
}
make sure to maintain CustomerState{ e.g. PlacedOrdered, Sold/Bought, Complete}
