How does trading work in the game Monopoly?

In the game Monopoly, trading is a strategic aspect that can dramatically influence the outcome of the game. Players trade properties to create monopolies or to build their asset portfolio, with the goal of bankrupting their opponents. A trade typically involves two players negotiating a deal where they exchange properties, money, or a combination of both. Deals often occur when a player wants to acquire a particular property to complete a color group or when a player is in need of cash. The terms of the trade are freely negotiated, and both parties must agree on the trade for it to be executed. Once an agreement is reached, players exchange the agreed-upon assets. Smart trading can provide a significant advantage, as owning sets of properties increases the rent charged to opponents, and building houses and hotels amplifies this effect, helping the player to secure victory.
