How Do Algorithmic Trading Strategies Aim to Minimize the Effective Spread?

Algorithmic strategies minimize the effective spread by intelligently interacting with the order book. They use techniques like "slicing" large orders, placing "iceberg" orders, and "pinging" the book to discover hidden liquidity.

By minimizing market impact and maximizing the chance of receiving a maker rebate, these algorithms aim to execute trades closer to the mid-price, thereby achieving a narrower effective spread.
