## Order Size

Order size is the quantity of an asset a trader intends to buy or sell in a single instruction. The size of an order relative to the total liquidity of the market is a key determinant of market impact and execution difficulty.

Large orders relative to available liquidity usually result in higher transaction costs and greater execution risk. Traders often divide large orders into smaller, more manageable blocks to navigate liquidity constraints.

Determining the optimal order size involves balancing the desire to enter or exit a position against the need to minimize adverse price impact. It is a critical component of position sizing and risk management within a broader trading strategy.
