Algorithm challenge

The final round of the challenge is already here! And surprise, no new products are introduced for a change. Dull? Probably not, as you do get another treat. The island exchange now discloses to you who the counterparty is you have traded against. This means that the counter_party property of the OwnTrade object is now populated. Perhaps interesting to see if you can leverage this information to make your algorithm even more profitable?

class OwnTrade:
    def __init__(self, symbol: Symbol, price: int, quantity: int, counter_party: UserId = None) -> None:
        self.symbol = symbol
        self.price: int = price
        self.quantity: int = quantity
        self.counter_party = counter_party
