What is Forex?

The Biggest Market You've Never Heard Of

Forex — short for foreign exchange — is the global marketplace where currencies are traded against each other. Every time you swap dollars for euros at the airport, you're participating in forex. The difference is that professional traders do this electronically, 24 hours a day, five days a week, from London trading floors to Tokyo bank desks to algorithmic servers in New Jersey data centers.

Note

Mind-blowing scale

The forex market trades over $7.5 trillion every single day according to the Bank for International Settlements (BIS) 2022 Triennial Survey. That's roughly 30x the daily volume of the entire US stock market. If you stacked $7.5 trillion in $100 bills, the pile would reach the Moon and back — twice.

The forex market has no central exchange like the NYSE or NASDAQ. It operates as an over-the-counter (OTC) network — a decentralized web of banks, brokers, and electronic networks connected digitally around the world. This decentralization is what allows it to run virtually 24 hours, as trading simply shifts from one financial center to the next as the Earth rotates.

Definition

Over-the-Counter (OTC)

A decentralized market where trading happens directly between two parties (e.g., bank-to-bank, broker-to-client) without a central exchange. The forex market is the world's largest OTC market, meaning there's no single building or exchange where all trades are executed.

Definition

Liquidity

The ability to buy or sell an asset quickly without significantly affecting its price. High liquidity means tight spreads and instant execution. Forex is the most liquid market in the world — you can enter and exit million-dollar positions in milliseconds on major pairs.


A Brief History of Forex

The modern forex market was born in 1971 when President Nixon ended the Bretton Woods system, which had pegged currencies to the US dollar (and the dollar to gold). Once currencies were allowed to float freely, their values were determined by supply and demand — and the forex market as we know it was born. The introduction of electronic trading in the 1990s then democratized access, allowing retail traders to participate alongside institutions for the first time.

Example

The Soros trade

In September 1992, George Soros famously shorted the British pound against the Deutsche Mark, betting that the UK couldn't maintain its ERM peg. He built a $10 billion short position. When the Bank of England capitulated and exited the ERM on September 16 (Black Wednesday), the pound collapsed and Soros reportedly netted over $1 billion in profit in a single day — proving that even central banks can't always fight the market.


Who Trades Forex?

The forex market is a complex ecosystem with many different participants, each with different motivations. Understanding who else is in the market helps you understand why prices move the way they do.

Retail TradersSpeculation & income generation~5-7%$100 – $100K
Algorithmic/HFT FirmsHigh-frequency market making & arbitrage~10-15%Millions of small trades

As a retail trader, you're swimming in the same ocean as massive institutional players. But don't be intimidated. The sheer size and liquidity of the market means there's room for everyone. Your advantage as a small trader is agility — you can enter and exit positions instantly without moving the market, something a hedge fund managing billions can't do.


Why Trade Forex?

A

Forex Advantages

  • Open 24 hours, 5 days a week — trade around your schedule
  • Extremely high liquidity — tight spreads on major pairs
  • Low barrier to entry — start with as little as $50
  • Profit in rising AND falling markets (go long or short)
  • No single entity can corner the market
  • Leverage allows controlling large positions with small capital
  • Low transaction costs compared to stocks or futures
  • Massive variety — dozens of currency pairs to trade

B

Forex Challenges

  • Leverage can amplify losses just as quickly as profits
  • Requires discipline and a written trading plan
  • News events cause sudden, violent volatility spikes
  • Over-trading is a common and costly beginner mistake
  • Scams and unregulated brokers exist — due diligence required
  • The 24-hour nature can lead to unhealthy screen time
  • Most retail traders lose money (industry statistics: ~70-80%)
  • Emotional control is harder than most people expect
Heads up

The 70-80% statistic

Regulated brokers are required to disclose that roughly 70-80% of retail traders lose money. This doesn't mean forex is a scam — it means most people trade without proper education, risk management, or discipline. By completing this course and practicing on paper first, you're already separating yourself from that majority.
