Two-Way Price: bid and ask quoting explained
By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.
Quick answer
A two-way price is a quote where a dealer shows both a bid and an ask simultaneously, committing to buy at the lower price and sell at the higher price. It signals genuine market-making intent, allowing the counterparty to deal either direction without revealing their interest first.
What is two way price?
A two-way price is the simultaneous quotation of a bid (the price at which the dealer will buy) and an ask or offer (the price at which the dealer will sell) for a defined size. The difference between the two is the spread, which compensates the dealer for inventory risk and provides the gross profit on the round-trip. Two-way quoting is the standard convention on interbank FX venues, ECN platforms, and institutional voice desks, and it distinguishes a genuine market maker from a one-sided participant who is merely seeking to buy or sell.
How traders use two way price
Retail traders see two-way prices on every broker platform, though the mechanics differ between dealing-desk and ECN routing. On a raw-spread account, the two-way price aggregates the best bid and best ask from underlying liquidity providers, with the broker adding commission rather than widening the spread. Institutional desks request two-way quotes from prime brokers when they want to disguise direction, since asking for a one-way price reveals intent and can move the market against them. The desk treats spread width as a real-time liquidity gauge: tight two-way quotes during London and New York overlap indicate deep participation, while spreads that widen sharply around major data releases or the Asian session open signal that market makers are pulling risk. Comparing the size available on each side also reveals dealer inventory pressure.
Common misconceptions about two-way prices
First, a two-way price is not a guarantee of execution at the displayed levels. Quoted size matters: the bid and ask may only be firm for a standard parcel, and larger orders typically receive a wider price. Second, the midpoint is not the fair value in any meaningful sense; it is simply the arithmetic centre of the spread. Third, identical-looking two-way prices across brokers can hide very different routing. One platform may internalise the order against its own book, while another passes it to external liquidity. The execution quality, not the headline quote, determines the true cost.

Frequently asked
Why do dealers quote two-way prices instead of just one side?
Quoting both sides is the defining function of a market maker. By committing to buy and sell simultaneously, the dealer provides liquidity to counterparties regardless of their direction, earns the spread on round-trip flow, and avoids revealing their own view. Regulators and venue rules on interbank platforms typically require continuous two-way quotes within agreed parameters, which is how market-making obligations are enforced in practice.
What determines the width of a two-way price?
Spread width reflects inventory risk, expected volatility, the size requested, the time of day, and the depth of competing liquidity. Major pairs like EUR/USD trade with very tight two-way prices during peak hours because dozens of dealers compete for flow. Exotic pairs, illiquid sessions, and moments around scheduled data releases see wider spreads as dealers price in the risk of being picked off by faster or better-informed counterparties.
Can a retail trader request a two-way price?
On standard retail platforms the two-way price is already displayed continuously, so there is nothing to request. On institutional voice or chat-based dealing, the convention is to ask for a price in a specific pair and size without disclosing direction, and the dealer responds with both bid and ask. Retail traders effectively receive this treatment automatically through their broker’s quote feed, though the quoted size is bounded by account and venue limits.
How does a two-way price differ from a last-traded price?
A two-way price is forward-looking and executable: it tells you where you can transact right now, in both directions. The last-traded price is historical, recording where a previous transaction occurred, and offers no commitment to future execution. In FX, which is decentralised and quote-driven rather than exchange-driven, the two-way price is the primary reference point, whereas equities markets often emphasise the last print alongside the current bid and ask.
