Price Discovery

Price discovery is the process by which a market arrives at a price that reflects current supply, demand and information. In forex it happens continuously across banks, electronic communication networks and broker platforms rather than at one exchange, so the quoted rate for a pair is the running result of competing bids and offers rather than a number set by an authority. New information — a central bank statement, an inflation release, a large hedging order — reaches price through trading: participants adjust the quotes they are willing to show, orders execute against them, and the consolidated best bid and offer moves. Liquidity shapes the process, because when depth is thin fewer trades are needed to shift the rate. Why it matters in practice: because there is no single exchange price for a currency pair, two brokers can legitimately show different quotes at the same instant and neither is wrong. What you can compare is how far a platform’s quote sits from a public reference at the same moment, and how it behaves when depth thins — at the New York close, across a rollover, or in the seconds after a data release. That behaviour, not the headline spread, is what a strategy actually trades against.
