The Foreign Exchange Market
Forex, short for foreign exchange, is the global marketplace where currencies are traded against one another. With a daily trading volume exceeding $7.5 trillion (as of 2024, according to the Bank for International Settlements), the forex market is by far the largest and most liquid financial market in the world — dwarfing the stock market, bond market, and commodities market combined.
Unlike stock exchanges that operate from a centralised location, the forex market is decentralised and operates electronically over the counter (OTC). This means there is no single physical exchange. Instead, currencies are traded through a vast network of banks, financial institutions, brokers, and individual traders across the globe, 24 hours a day, five days a week.
Every time you exchange money at an airport, buy a product priced in a foreign currency, or a corporation pays an overseas supplier, a forex transaction takes place. However, the vast majority of forex trading is speculative — traders seek to profit from fluctuations in exchange rates between currency pairs.

How Forex Trading Works
Forex trading always involves simultaneously buying one currency and selling another. Currencies are quoted in pairs, and the price reflects the exchange rate between the two.
Currency Pairs
Currencies are always traded in pairs, such as EUR/USD. The first currency (EUR) is the base currency, and the second (USD) is the quote currency. If EUR/USD is 1.0850, it costs $1.0850 to buy one euro.
Buying (Going Long)
If you believe the base currency will strengthen against the quote currency, you buy the pair (go long). For example, buying EUR/USD at 1.0850 and selling at 1.0900 earns you 50 pips profit.
Selling (Going Short)
If you believe the base currency will weaken, you sell the pair (go short). In forex, you can profit from falling prices just as easily as rising ones — this is one of the market's unique advantages.
Spreads & Costs
The spread is the difference between the buy (ask) and sell (bid) price. This is typically the main cost of trading forex. At QuantaraEX, spreads start from as low as 0.0 pips on ECN accounts.
Leverage & Margin
Leverage allows you to control a larger position with a smaller deposit (margin). With 1:100 leverage, a $1,000 margin can control a $100,000 position. While leverage amplifies profits, it equally amplifies losses.
Pips & Lot Sizes
A pip is the smallest standard price movement (0.0001 for most pairs). A standard lot is 100,000 units. A 1-pip move on one standard lot of EUR/USD equals approximately $10.
Major, Minor & Exotic Pairs
Currency pairs are categorised into three groups based on their trading volume and the economies they represent. The seven major pairs account for roughly 80% of all forex trading volume.
Major Pairs
| Pair | Name | Avg. Spread |
|---|---|---|
| EUR/USD | Euro / US Dollar | 0.6 pips |
| GBP/USD | British Pound / US Dollar | 0.9 pips |
| USD/JPY | US Dollar / Japanese Yen | 0.7 pips |
| USD/CHF | US Dollar / Swiss Franc | 1.2 pips |
| AUD/USD | Australian Dollar / US Dollar | 0.8 pips |
| USD/CAD | US Dollar / Canadian Dollar | 1.0 pips |
| NZD/USD | New Zealand Dollar / US Dollar | 1.2 pips |
Minor Pairs (Crosses)
Minor pairs do not include the US Dollar but feature other major currencies. They typically have wider spreads and somewhat lower liquidity than the majors.
Exotic Pairs
Exotic pairs combine a major currency with one from an emerging or smaller economy. They carry higher spreads and volatility but can offer unique trading opportunities.
Forex Market Hours
The forex market operates 24 hours a day from Sunday evening to Friday evening (GMT). This is possible because trading passes through four major sessions around the world as the business day moves from east to west.
| Session | Open (GMT) | Close (GMT) | Key Currencies |
|---|---|---|---|
| Sydney | 22:00 | 07:00 | AUD, NZD |
| Tokyo | 00:00 | 09:00 | JPY, AUD |
| London | 08:00 | 17:00 | EUR, GBP, CHF |
| New York | 13:00 | 22:00 | USD, CAD |
Peak Liquidity & Volatility
The highest trading volume occurs during the London-New York overlap (13:00 - 17:00 GMT), when both sessions are active simultaneously. This window typically offers the tightest spreads and the most significant price movements, making it the preferred trading period for many forex traders.
Advantages of Forex Trading
The forex market offers several unique benefits that make it attractive to both new and experienced traders.
Unmatched Liquidity
With over $7.5 trillion traded daily, the forex market ensures you can enter and exit positions almost instantly at your desired price, even with large volumes.
24-Hour Market Access
Trade around the clock from Sunday evening to Friday night. Unlike stock markets that close at the end of each business day, forex allows you to react to news events in real time.
Profit in Rising & Falling Markets
Since forex involves buying one currency while selling another, you can profit whether a pair is trending up or down. Going short is just as straightforward as going long.
Low Transaction Costs
Forex trading costs are typically built into the spread, with no separate commissions on standard accounts. QuantaraEX offers spreads from 0.0 pips on ECN accounts.
Flexible Leverage
Leverage allows you to trade positions larger than your account balance. At QuantaraEX, leverage options range from 1:1 up to 1:500 depending on your account type and regulatory framework.
Low Barriers to Entry
You can start trading forex with a relatively small deposit. QuantaraEX accounts can be opened with as little as $100 and micro lots (0.01) allow you to manage risk precisely.
Understanding the Risks
Forex trading offers significant opportunities, but it also carries substantial risks that every trader must understand before committing real capital.
Leverage Risk
While leverage amplifies potential profits, it equally magnifies losses. A 1% adverse move on a 1:100 leveraged position results in a 100% loss of your margin. Always use appropriate position sizing and stop-loss orders.
Market Volatility
Currency prices can move rapidly due to economic data releases, geopolitical events, or central bank decisions. Sudden spikes in volatility can trigger stop-losses or lead to slippage on orders.
Gap Risk
Prices can gap between Friday close and Sunday open, or during major news events. Weekend gaps can cause your position to open Monday at a significantly different price than Friday's close.
Counterparty Risk
In the OTC forex market, your broker is your counterparty. It is essential to trade with a well-regulated and reputable broker like QuantaraEX to protect your funds.
Emotional Trading
Fear, greed, and overconfidence are common pitfalls. A disciplined trading plan with predefined entry, exit, and risk rules is essential for long-term success.
Over-Trading
The 24-hour nature of forex can tempt traders to over-trade. Quality setups matter more than quantity. Define your trading sessions and stick to your strategy.
Important: Between 70-80% of retail investor accounts lose money when trading CFDs and Forex. You should consider whether you understand how these products work and whether you can afford to take the high risk of losing your money. Never invest more than you can afford to lose, and always practice with a demo account before trading live.
Forex Glossary
Essential terminology every forex trader should know.
Pip
The smallest price increment in a currency pair, typically the fourth decimal place (0.0001). For JPY pairs, it is the second decimal place (0.01).
Lot
A standardised unit of trade. A standard lot equals 100,000 units of the base currency. Mini lots (10,000) and micro lots (1,000) are also available.
Spread
The difference between the bid (sell) price and the ask (buy) price of a currency pair. This is the primary cost of trading.
Leverage
The ability to control a large position with a relatively small amount of capital. For example, 1:100 leverage lets you control $100,000 with $1,000.
Margin
The amount of capital required to open and maintain a leveraged position. It acts as a good-faith deposit rather than a fee.
Bid / Ask
The bid price is the highest price a buyer will pay; the ask price is the lowest price a seller will accept.
Base / Quote
In EUR/USD, EUR is the base currency and USD is the quote currency. The price tells you how much quote currency you need to buy one unit of the base.
Long / Short
Going long means buying a currency pair (expecting the base to rise). Going short means selling (expecting the base to fall).
