π¦ Market Structure
What is the Forex market?β
Forex (Foreign Exchange), also called FX, is the global market where currencies are bought and sold continuously. Unlike stock exchanges β which have a centralized trading venue (NYSE, NASDAQ, B3) β Forex operates OTC (Over-The-Counter): transactions happen directly between participants over a global electronic network with no single physical location.
The average daily volume exceeds $7.5 trillion, according to the Bank for International Settlements (BIS) Triennial Survey. That is roughly 25 times the daily volume of all global stock markets combined. The market is deep enough that even billion-dollar institutional orders rarely cause significant price distortions in the most-traded pairs.
Why Forex is structurally differentβ
| Property | Forex | Stock market |
|---|---|---|
| Trading venue | Decentralized OTC network | Centralized exchange |
| Hours | 24h/day, 5 days/week | Exchange business hours |
| Liquidity | $7.5 trillion/day | ~$300 billion/day (global equities) |
| Direction | Always long one currency, short another | Typically long-only for retail |
| Leverage | High (regulated by jurisdiction) | Lower for most equity products |
| Price setter | Interbank network | Exchange order book |
Key structural properties:
- 24/5 availability β As the market follows the sun across continents, when Tokyo closes, London opens; when London ends, New York is in full swing.
- Massive liquidity β In major pairs like EUR/USD, GBP/USD or USD/JPY, execution is near-instant with tight spreads.
- Bilateral β Every time one currency rises, another falls. There is always an opportunity on both sides.
- Accessibility β With a regulated broker or a protocol like HyperFX, anyone with internet access can participate.
The interbank marketβ
Forex has no headquarters. What exists is an electronic network known as the interbank market, where the world's largest banks trade currencies among themselves in enormous volumes β often hundreds of millions of dollars per transaction. These banks act as dealers, providing bid and ask quotes to the rest of the market.
Approximately two thirds of all global Forex volume passes through about ten investment banks: JP Morgan, Citi, UBS, Deutsche Bank, Goldman Sachs, HSBC, Barclays, BNP Paribas, Morgan Stanley, and Bank of America.
Below the interbank tier are: institutional brokers, hedge funds, ECNs (Electronic Communication Networks), retail brokers β and, at the protocol layer, HyperFX. Each layer passes a small spread premium through to the next.
Trading sessionsβ
The daily Forex cycle is divided into three major sessions, each centered on a financial hub:
| Session | UTC hours | Key currencies | Characteristics |
|---|---|---|---|
| Asian (Tokyo) | 00:00 β 09:00 | JPY, AUD, NZD | Lower volatility on most pairs; JPY crosses most active |
| European (London) | 08:00 β 17:00 | EUR, GBP, CHF | Highest volume β ~35% of global daily volume |
| American (New York) | 13:00 β 22:00 | USD, CAD | Strong USD pair activity; major US data releases |
The LondonβNew York overlap (13:00β17:00 UTC) is the highest-liquidity and highest-volatility window of the day β the preferred trading window for many professional traders.
Market participantsβ
The hierarchy of participants directly influences how prices form:
| Participant | Role |
|---|---|
| Central banks | Manage national currency reserves, set interest rates, occasionally intervene directly in the FX market |
| Commercial & investment banks | Primary liquidity providers; their trading desks quote prices to the rest of the market |
| Multinational corporations | Convert revenues between currencies β e.g., Apple selling iPhones in Japan receives yen, converts to dollars |
| Hedge funds & asset managers | Speculative and hedging strategies across medium to long horizons |
| Retail brokers | Provide market access to individual traders, usually with leverage |
| DeFi protocols (e.g. HyperFX) | On-chain execution layer: public CLOB, oracle-priced, non-custodial |
| Individual traders | The newest and most numerous layer; smaller individual orders but significant aggregate volume |
How HyperFX fits into the market structureβ
Traditional retail brokers sit at Tier 3 β they are custodians of your funds and often market-makers (taking the other side of your trade). HyperFX replaces the broker with a smart contract: your funds stay in your wallet, prices come from a public oracle, and order matching happens on-chain via a CLOB β the same mechanism used at Tier 1 exchanges, now accessible to any wallet.
