Introduction to Forex: How Currency Pairs, Pips, and Leverage Work

The foreign exchange market (forex or FX) is the largest financial market in the world — approximately $7.5 trillion in daily trading volume as of the 2022 BIS Triennial Survey. That is roughly 30x the daily volume of the entire U.S. stock market. Forex is where currencies are traded against each other — dollars for euros, yen for pounds, francs for yuan — 24 hours a day, five days a week. Understanding forex matters even if you never trade currencies because exchange rates affect everything in international finance: the cost of imports and exports, the returns on foreign investments, the competitiveness of multinational companies, and the transmission of monetary policy across borders. When the Fed raises interest rates and the dollar strengthens, that is a forex event with consequences for every global market. Forex differs from stock trading in fundamental ways. There is no central exchange — forex is an over-the-counter (OTC) market where banks, institutions, and brokers trade directly with each other. The market operates 24 hours across three overlapping sessions: Asian (Tokyo), European (London), and North American (New York). And currencies are always traded in pairs, which means every forex trade is simultaneously a bet on one currency getting stronger and another getting weaker.

Every forex price is a pair: EUR/USD, GBP/JPY, USD/CAD. The first currency is the base currency. The second is the quote currency. The price tells you how much of the quote currency you need to buy one unit of the base currency. Example: EUR/USD = 1.0850 means 1 euro costs 1.0850 U.S. dollars. If you buy EUR/USD (go long), you are buying euros and selling dollars — you profit if the euro strengthens against the dollar (the price goes up). If you sell EUR/USD (go short), you are selling euros and buying dollars — you profit if the euro weakens (the price goes down). The major pairs all include the U.S. dollar: EUR/USD (Euro/Dollar — the most traded pair, accounting for ~22% of global volume), USD/JPY (Dollar/Yen — influenced heavily by Bank of Japan policy), GBP/USD (Pound/Dollar — often called Cable), USD/CHF (Dollar/Swiss Franc — the Swiss franc is considered a safe haven), AUD/USD (Australian Dollar — commodity-linked, moves with iron ore and Chinese demand), and USD/CAD (Dollar/Canadian Dollar — moves with oil prices). Cross pairs exclude the U.S. dollar: EUR/GBP, EUR/JPY, GBP/JPY. These are actively traded but generally have wider spreads (the difference between the buy and sell price) than the majors. The bid/ask spread is the transaction cost in forex. If EUR/USD is quoted as 1.0848/1.0850, the bid (what you sell at) is 1.0848 and the ask (what you buy at) is 1.0850. The 2-pip spread is the broker's profit and your cost to enter the trade.

A pip (percentage in point) is the standard unit of price movement in forex. For most currency pairs, a pip is the fourth decimal place: a move from 1.0850 to 1.0851 is one pip. For yen pairs (where the quote currency is JPY), a pip is the second decimal place: a move from 148.50 to 148.51 is one pip. Pip value depends on three factors: the pip size (0.0001 for most pairs, 0.01 for yen pairs), the position size (measured in lots — a standard lot is 100,000 units of the base currency), and the quote currency. For EUR/USD with a standard lot: pip value = 0.0001 x 100,000 = $10 per pip. A 50-pip move in your favor on a standard lot = $500 profit. A 50-pip move against you = $500 loss. Mini lots (10,000 units, $1 per pip on EUR/USD) and micro lots (1,000 units, $0.10 per pip) allow smaller position sizes — important for risk management and for traders with smaller accounts. The practical importance: pip value tells you the actual dollar amount at risk. If your stop loss is 30 pips away and you are trading a mini lot on EUR/USD, your risk is 30 x $1 = $30. If you are trading a standard lot, the same 30-pip stop = $300 risk. Position sizing in forex starts with the pip value calculation — you work backward from your maximum dollar risk to determine the appropriate lot size.

Forex brokers offer leverage ratios of 50:1, 100:1, or even 500:1 in some jurisdictions. A 100:1 leverage means you control $100,000 of currency (a standard lot) with just $1,000 of your own capital (called margin). The broker lends you the rest. This sounds amazing until you do the math on losses. At 100:1 leverage on a standard lot, a 50-pip move in your favor = $500 profit on your $1,000 margin = 50% return. The same 50-pip move against you = $500 loss = 50% of your margin gone. A 100-pip adverse move (entirely normal in volatile markets) wipes out your entire $1,000 margin. Here is the uncomfortable truth that retail forex marketing does not emphasize: approximately 70-80% of retail forex accounts lose money (this statistic is required to be disclosed by regulated brokers in the EU, and the numbers are consistent globally). Leverage is the primary reason. The 20-30% who profit are typically using lower leverage (5:1 to 20:1), strict risk management, and treating forex as a serious analytical discipline rather than a get-rich-quick scheme. U.S. regulations cap leverage at 50:1 for major pairs and 20:1 for minors. European ESMA regulations cap at 30:1 for majors and 20:1 for minors. These limits exist specifically because higher leverage ratios led to widespread retail account blowups. The lower the leverage you use, the more your forex trading resembles stock trading — manageable position sizes with survivable drawdowns. The rule of thumb for responsible leverage use: risk no more than 1-2% of your account on any single trade. With a $10,000 account risking 1% ($100), a 30-pip stop on EUR/USD with $10/pip (standard lot) would risk $300 — three times your limit. You should be trading a mini lot ($1/pip) instead, limiting your loss to $30 on that same 30-pip stop.
