Pegged-to-Market Order

A pegged-to-market order is an order type whose price automatically tracks a reference point in the order book, typically the best bid or best ask, adjusting as the market moves rather than sitting at a fixed level. A buyer pegging to the best bid, for example, keeps their order competitively placed without manually repricing it, often with an optional offset and a limit cap.

Why it matters

Pegged orders automate the tension between execution speed and price. A fixed limit order can be left behind by a moving market, while a market order pays the spread and slippage. Pegging keeps an order competitively positioned continuously, which is useful in fast markets and essential in crypto, where prices move around the clock while traders sleep. Several major crypto and traditional venues support pegged variants, including primary peg, market peg and midpoint peg, each anchoring to a different book reference, and the order type is a building block of market-making strategies that continuously quote both sides of the book.

In the gold vs bitcoin debate

Order types like this exist because bitcoin trades on continuous electronic books at all hours, market microstructure it shares with equities and futures rather than with physical gold, whose retail buyer faces dealer quotes instead of a book. Traders wanting gold exposure with similar tooling use futures or ETFs; the underlying metal itself never offers it.
