Order Execution

Order execution is the process by which a submitted trade order is matched against the market and filled. Execution quality is measured by how close the achieved price is to the price at decision time, with the difference, slippage, driven by spread, market depth and speed. A market order executes immediately at the best available prices; a limit order executes only at its stated price or better.

Why it matters

For any meaningful size, execution is a cost center of its own. A large market order walks through the book, consuming successive price levels, so institutions slice orders over time, use algorithms targeting volume-weighted average prices, or route to OTC desks that quote a single price for the block. In crypto, execution spans hundreds of venues with fragmented liquidity, so the same order can fill at visibly different prices across exchanges, with arbitrage keeping them loosely aligned.

In the gold vs bitcoin debate

Execution friction is where the two assets' market structures diverge most for ordinary holders. A retail bitcoin buyer gets near-instant execution at spreads of a few basis points, twenty-four hours a day. A retail gold buyer pays dealer premiums that commonly run several percent on coins, and selling involves shipping, verification or in-person dealing. At institutional scale the comparison narrows, since gold's OTC market handles large blocks routinely.
