How the Forex Market Works: Currencies, Pairs, Prices

Introduction

Forex trading short for foreign exchange trading is the act of buying one currency while simultaneously selling another. Every time you trade a currency pair, you're essentially placing a bet on whether one currency will strengthen or weaken against another.
Here's the simplest way to think about it when you travel abroad and exchange your home currency for local money you've participated in the forex market. Traders do the same thing, except they're trying to profit from the constant fluctuations in exchange rates.

So, what is forex trading in practical terms?

• You buy EUR/USD at 1.0850 because you believe the euro will strengthen against the dollar.

• The rate moves to 1.0870.

• You close the trade and pocket the difference measured in "pips."

That's the core concept everything else leverage, lot sizes, spreads, swaps is just the machinery around this simple idea.

For beginners, the most important thing to internalize is this: forex is about relative value. You're never buying a currency in isolation. You're always comparing it against another.

The Global Foreign Exchange Market: Structure and Size

The foreign exchange market moves over $7.5 trillion per day according to the Bank for International Settlements' 2022 Triennial Survey. That's more than the combined daily volume of all global stock markets.

Unlike stock exchanges forex doesn't operate from a single physical location. It's an over-the-counter (OTC) market, meaning trades happen directly between participants banks institutions, brokers and retail traders through electronic networks.

The market operates 24 hours a day five days a week rotating through four major trading sessions:

• Sydney (Asian session open)

• Tokyo (Asian session peak)

• London (European session highest volume)

• New York (US session overlaps with London for peak liquidity)

This continuous cycle means you can trade forex at almost any hour. But not all hours are created equal more on that later.

Decentralized but Connected: Interbank vs. Retail Forex Trading

The forex market has layers. At the top sits the interbank market, where massive institutions like JPMorgan, Deutsche Bank and Citigroup trade billions in currency daily. This is where the real price discovery happens.

Below that you have tier-1 liquidity providers then brokers and finally retail traders like you and me.

As a retail trader, you're accessing the market through a broker who bridges your orders to their liquidity providers. This is why broker selection matters enormously especially for prop firm traders. A bad broker with poor execution, wide spreads and requotes can destroy a strategy that would otherwise be profitable.

If you're trading a prop firm funded account your edge doesn't just come from your strategy it comes from the infrastructure around it.

How Does Forex Trading Work? The Mechanics of Profit & Loss

Let's get into the nuts and bolts. Understanding how profit and loss are calculated is non-negotiable.

Pips, Lots, and Leverage in Forex

A pip (percentage in point) is the smallest standard unit of price movement in a currency pair. For most pairs that's the fourth decimal place. If EUR/USD moves from 1.0850 to 1.0851 that's a 1-pip move. For pairs involving the Japanese yen a pip is the second decimal place.

Lot sizes determine how much each pip is worth:

Leverage allows you to control a larger position with a smaller amount of capital. A 1:50 leverage means you can control $50,000 with just $1,000. Leverage amplifies both gains and losses which is why it's the single most dangerous tool in a beginner's hands.

Here's a real example:

• You open a 0.50 lot (mini lot) buy position on EUR/USD at 1.0850.

• The price moves to 1.0870 a 20-pip gain.

• Profit: 50,000 units × 0.0020 = $100 profit.

Same move, but with a stop loss hit at 1.0840? That's a $100 loss on a single trade.

This is why prop firm traders obsess over risk per trade. A 2% account drawdown on one bad position can put your challenge at risk.

Currency Pairs: The Basics

Every forex trade involves a currency pair two currencies paired together. The first currency is the base currency, and the second is the quote currency.

• When you see EUR/USD = 1.0850 it means 1 euro is worth 1.0850 US dollars.

• If you buy EUR/USD you're buying euros and selling dollars.

• If you sell EUR/USD you're selling euros and buying dollars.

Major, Minor, and Exotic Pairs

Currency pairs fall into three categories:

• Major Pairs: Always involve the US dollar paired with another major currency. These have the tightest spreads and highest liquidity: EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD, USD/CAD, NZD/USD

• Minor Pairs (Crosses): Two major currencies paired without the USD. Slightly wider spreads: EUR/GBP, EUR/JPY, GBP/JPY, AUD/NZD, EUR/AUD

• Exotic Pairs: A major currency paired with an emerging or small economy currency. Wide spreads, high volatility: USD/TRY, EUR/ZAR, USD/MXN, GBP/SGD

For prop firm traders, stick to majors and a few select minors. Exotics can move 100+ pips in minutes which is a recipe for blowing through drawdown limits.

Price Action in Forex: What Drives Value?

Currency prices move based on a complex web of factors:

• Interest rate decisions: Higher interest rates attract foreign capital, strengthening a currency.

• Economic data: GDP, employment figures, inflation (CPI) and retail sales all move markets.

• Geopolitical events: Elections, wars, trade disputes create uncertainty and volatility.

• Central bank policy: Forward guidance from the Fed, ECB, BOJ or BOE can move pairs before any actual rate change.

• Market sentiment: Sometimes currencies move simply because the market is positioned too heavily in one direction.

Understanding why prices move helps you anticipate volatility. The Economic Calendar is your best friend always check it before placing trades especially during prop firm challenges where an unexpected news spike can liquidate your position in seconds.

Common Forex Trading Strategies

There's no single "best" trading strategy. The right approach depends on your personality schedule and risk tolerance. Here are the most widely used frameworks:

Scalping, Day Trading and Position Trading

• Scalping: Holding trades for seconds to minutes, aiming for 5-15 pips per trade. Requires intense focus and low-spread execution. Not ideal during high-volatility news events.

• Day Trading: Trades are opened and closed within the same session Typically holds positions for 30 minutes to a few hours Good for traders who can monitor charts during specific sessions.

• Position Trading: Holding trades for days or weeks based on macroeconomic trends Lower time commitment but requires patience and larger stop losses.

For prop firm traders day trading during the London/NY overlap (12:00 to 16:00 GMT) tends to offer the best risk-adjusted setups Liquidity is high, spreads are tight and technical levels tend to respect structure.

Best Times to Trade Forex

Not all trading hours are equal. Here's a quick breakdown:

The London/NY overlap is where the magic happens. This is when institutional order flow is at its peak and technical levels are most reliable.

How to Choose the Right Currency Pair to Trade

Not every pair deserves your attention. Here's a framework for narrowing your focus:

1. Check the spread If the spread is above 2-3 pips on a major pair, something is off. Move on.

2. Assess volatility: Use ATR (Average True Range) to understand how much a pair typically moves per day. Match this to your risk parameters.

3. Understand correlation: EUR/USD and GBP/USD often move together. Trading both in the same direction doubles your exposure without doubling your edge.

4. Know the session: AUD and JPY tend to be more active during the Asian session. EUR and GBP dominate during London.

5. Respect the calendar: Don't trade EUR/USD 5 minutes before a Fed rate decision unless you have a specific plan for volatility.

Quick tip: Pick 2-3 pairs and master them. Deep knowledge of one pair's behavior will outperform shallow knowledge of ten.

Common Causes of Failure in Forex Trading

Let's be honest about why most traders fail because awareness is the first step to avoiding it.

1. Overleveraging: The #1 account killer. High leverage turns small moves into catastrophic losses.

2. No trading plan: Entering trades based on gut feeling, signals from Telegram groups and "I have a feeling about this one."

3. Ignoring risk management: Risking 10-20% of the account on a single trade. One losing streak and you're done.

4. Revenge trading: After a loss, immediately jumping back in to "make it back." This is emotional trading, and it always ends badly.

5. Trading during low-liquidity sessions: Thin markets produce erratic price action that stops out technical setups.

6. Chasing perfection: Waiting for the "perfect" entry while missing the actual move. Good trades happen in zones, not at exact prices.

If you're failing in forex, it's almost certainly one (or several) of these reasons. The market isn't out to get you. Your own habits are.
