FX Glossary

Terms drawn from Modules 1-5 of the FX Fundamentals track. Practical, not textbook.

Appreciation

When a currency increases in value relative to another. If EUR/USD moves from 1.0800 to 1.0900, the euro has appreciated — it now costs more dollars to buy one euro. Don't confuse this with the direction of the quote: in USD/JPY, a move from 149 to 150 means the dollar appreciated, not the yen.

Ask (Offer)

The price at which a dealer is willing to sell the base currency. If EUR/USD is quoted at 1.0848 / 1.0852, the ask is 1.0852. You always buy at the ask — the worse price for you, the better price for the dealer. That's how the spread works.

Balance of Payments (BoP)

The record of all economic transactions between a country and the rest of the world. Split into the current account (trade, investment income, transfers) and the capital/financial account (investment flows, reserves). The BoP must balance — a current account deficit is always matched by a capital account surplus.

Base Currency

The first currency in a pair. In EUR/USD, EUR is the base. The exchange rate tells you how many units of the quote currency you need to buy one unit of the base. There's a hierarchy: EUR is always base, followed by GBP, AUD, NZD, then USD against most remaining currencies.

Basis (CIP Basis)

The deviation of the forward rate from what covered interest rate parity predicts. Before 2008, the basis was essentially zero. Since then, persistent deviations have emerged — particularly for USD — reflecting bank funding stress and regulatory constraints that prevent full arbitrage.

Bid

The price at which a dealer is willing to buy the base currency. If EUR/USD is quoted at 1.0848 / 1.0852, the bid is 1.0848. You always sell at the bid. The bid is always lower than the ask — the difference is the spread.

Big Figure

The first few digits of an exchange rate that are assumed to be known by both parties. For EUR/USD at 1.0850, the big figure is 1.08. Interbank dealers don't quote it — they just say "fifty" meaning 1.0850. Getting the big figure wrong is one of the most embarrassing mistakes you can make on a desk.

Carry Trade

A strategy of borrowing in a low-interest-rate currency and investing in a high-interest-rate currency to earn the differential. Works well in calm markets, devastating during risk-off episodes. The forward market already prices in the differential (via CIP), so carry only works if you leave the FX exposure unhedged.

Conditional VaR (CVaR) / Expected Shortfall

The average loss in the tail beyond the VaR threshold. If your 95% VaR is $500,000, CVaR tells you the average of the losses that exceed $500,000. More useful than VaR for understanding tail risk because VaR is silent on how bad the bad days actually get.

Counterparty Risk

The risk that the other party in a trade fails to deliver. In OTC markets like FX, every trade is a bilateral agreement — there's no central clearinghouse guaranteeing settlement. If your forward is in-the-money and the other side goes bankrupt, you have a problem.

Covered Interest Rate Parity (CIP)

The no-arbitrage condition stating that the forward premium or discount must exactly offset the interest rate differential between two currencies. If it doesn't, riskless profit is available. CIP is the closest thing to a law of physics in FX. It held almost perfectly until 2008.

Cross Rate

An exchange rate calculated from two other rates using a common currency (usually USD) as a bridge. If you know EUR/USD and GBP/USD, you can calculate EUR/GBP. The spread on a cross rate is always wider than either constituent — you're paying for two transactions.

Depreciation

When a currency decreases in value relative to another. If EUR/USD falls from 1.0900 to 1.0800, the euro has depreciated. Depreciation isn't inherently bad — it makes exports cheaper and can boost competitiveness. But uncontrolled depreciation destroys purchasing power.

Direct Quote

An exchange rate where your home currency is the quote (price) currency. For a US-based trader, EUR/USD = 1.0850 is direct — it tells you how many dollars it costs to buy one euro. A rising direct quote means your home currency is weakening.

Economic Exposure (Operating Exposure)

The risk that exchange rate movements affect a company's future cash flows and competitive positioning. Harder to measure than transaction exposure because it involves assumptions about future business conditions. A Japanese automaker's entire business model is an economic exposure to USD/JPY.

FX Swap

A spot trade and a forward trade packaged together — buy spot, sell forward (or vice versa). The most traded instrument in FX, accounting for roughly 50% of daily turnover. Used primarily for funding and rolling positions. When dealers talk about "rolling" a position, they're using swaps.

Forward Contract

An agreement to exchange currencies at a specific rate on a specific future date. The forward rate is not a prediction — it's determined by the interest rate differential between the two currencies. Forwards are the primary tool for hedging known FX exposures.

Forward Discount

When the forward rate for the base currency is lower than the spot rate. This happens when the base currency has higher interest rates. The higher-yield currency trades at a discount in the forward market to offset its interest rate advantage. Not a prediction of depreciation — just math.

Forward Points

The difference between the forward rate and the spot rate, expressed in pips. Forward points are determined by the interest rate differential. Positive points mean the base currency is at a forward premium; negative points mean a forward discount.

Forward Premium

When the forward rate for the base currency is higher than the spot rate. This happens when the base currency has lower interest rates. The lower-yield currency trades at a premium in the forward market.

Front-Running

Illegally trading ahead of a client's order for your own benefit. A career-ending offence on any dealing desk. Distinct from using aggregate flow information to manage risk, which is normal and expected. The line: you can't trade ahead of a specific order, but you can read the general tone of flow.

Hedge Ratio

The percentage of an FX exposure that is hedged. 100% = fully hedged (complete certainty, no upside). 0% = fully unhedged (full exposure). Most corporates hedge 50-80%, balancing protection with flexibility. The optimal ratio depends on cash flow certainty, risk tolerance, and natural hedges.

Indirect Quote

An exchange rate where your home currency is the base currency. For a US-based trader, USD/JPY = 149.50 is indirect — it tells you how many yen you get per dollar. A rising indirect quote means your home currency is strengthening.

Interbank Market

The top tier of the FX market where major dealing banks trade with each other. JP Morgan, Citi, Deutsche Bank, UBS, HSBC, Barclays — these are the market makers. They quote prices to each other and to clients continuously. When you hear "the market," this is what people mean.

International Fisher Effect (IFE)

The theory that the currency of the country with higher nominal interest rates should depreciate by approximately the interest rate differential. Links interest rates to inflation expectations to exchange rate movements. Works better over long horizons.

Last Look

A short window (50-200ms) in electronic FX trading during which a liquidity provider can reject your trade after you've clicked. Controversial — defenders say it protects against latency arbitrage, critics say it lets banks trade against clients.

Liquidity

The ease with which you can trade a currency pair without moving the price. EUR/USD in London hours = deep liquidity (1-2 pip spreads). USD/TRY in Asian session = thin liquidity (wide spreads, slippage risk). Liquidity is a privilege, not a right.

Mark-to-Market (MTM)

Calculating the current value of an outstanding position based on today's market prices, even before settlement. For forwards, compare your locked-in rate against the current forward rate for the same settlement date, then discount to present value. This is how daily P&L is measured on a dealing desk.

Market Maker

An institution that quotes both bid and ask prices continuously and is willing to trade at those prices. Market makers earn the spread but take on risk from client flow. The major interbank banks are the primary market makers in FX.

Money Market Hedge

Replicating a forward hedge by borrowing in one currency, converting at spot, and investing in another currency. Economically equivalent to a forward contract through CIP. Useful when forward markets are illiquid or when you can access better rates.

OTC (Over-the-Counter)

A market where trades are private bilateral agreements, not executed on a central exchange. The FX market is OTC — there's no NYSE of currencies. This means no single "correct" price, variable liquidity, and counterparty risk.

Pip

The smallest standard price increment. For most pairs, it's the fourth decimal place (0.0001). For JPY pairs, it's the second decimal place (0.01). When a dealer says EUR/USD moved "50 pips," they mean a move of 0.0050.

Purchasing Power Parity (PPP)

The theory that exchange rates should equalize prices across countries. Absolute PPP (compare price levels) rarely holds. Relative PPP (compare inflation differentials) works better over long horizons — the higher-inflation currency depreciates. The Big Mac Index is the best-known PPP measure.

Quote Currency (Price Currency)

The second currency in a pair. In EUR/USD, USD is the quote currency. The exchange rate tells you how many units of the quote currency it costs to buy one unit of the base.

Settlement Date

The date when currencies actually change hands. For spot trades, this is T+2 (two business days after trade date). Exceptions: USD/CAD, USD/TRY, and USD/RUB settle T+1. For forwards, the settlement date is whatever was agreed in the contract.

Spot Rate

The current exchange rate for immediate (T+2) delivery. The reference point for everything in FX — forwards, swaps, options all derive from spot. When someone says "EUR/USD is at 1.0850," they mean the spot rate.

Spread

The difference between the bid and ask price. EUR/USD in normal conditions: 1-2 pips. Exotic pairs: 20-50+ pips. The spread reflects liquidity, volatility, time of day, and trade size. It's the dealer's compensation for taking on risk — and your transaction cost.

Stress Test

Analyzing portfolio impact from specific extreme scenarios — a 500-pip overnight move, a peg break, a liquidity freeze. Complements VaR by answering "how bad could it get in this specific scenario?" rather than "what's the statistical worst case?"

T+2

The standard settlement convention for spot FX trades — currencies change hands two business days after the trade date. A historical convention from when cross-border wire transfers physically took two days.

Tail Risk

The risk of extreme market moves that occur more frequently than normal distributions predict. The CHF de-peg (30%+ in minutes), GBP flash crash (6% in two minutes), EM currency collapses — these are tail events. VaR systematically underestimates tail risk.

Transaction Risk

The risk that the value of a specific FX cash flow changes before settlement. A company with a €5 million receivable due in 90 days faces transaction risk if EUR/USD moves unfavorably. The most straightforward type of FX risk to identify and hedge.

Translation Risk

The risk that foreign assets or liabilities change in home-currency value when translated for financial reporting. A US company with €500 million in European operations sees those assets fluctuate in dollar terms every quarter — even without any FX transaction.

Triangular Arbitrage

Exploiting inconsistencies between three exchange rates. If the cross rate implied by two pairs doesn't match the quoted cross rate, there's risk-free profit available. In practice, algorithms eliminate these opportunities in milliseconds. The concept matters because it's the enforcement mechanism that keeps cross rates consistent.

Uncovered Interest Rate Parity (UIP)

The theory that the expected change in the spot rate should equal the interest rate differential. Empirically fails — high-yield currencies tend to appreciate, not depreciate. This failure is why the carry trade is profitable. The forward rate reflects CIP (arbitrage), not UIP (expectations).

Value at Risk (VaR)

The maximum expected loss over a given time period at a given confidence level. "1-day 95% VaR of $500,000" means losses should exceed $500,000 on roughly 5% of days. Critical limitation: says nothing about how much losses exceed the threshold. Use alongside CVaR and stress tests.

Tools & Platforms

An honest guide to the tools aspiring FX traders should know. No affiliate links, no sponsored placements — just practical guidance from someone who's used institutional and retail platforms.

Charting & Analysis

TradingView

The best charting platform for most traders. Browser-based, so it works on any device. Excellent charting tools, a massive library of community-built indicators, and real-time data across most markets. The free tier is genuinely usable; the paid tiers add more indicators, alerts, and data. If you're doing technical analysis, start here.

What it's good for: charting, technical analysis, idea sharing, screening.

What it's not: it's not an execution platform (though it connects to some brokers). It's not a replacement for understanding what you're looking at — good charts don't make good traders.

MetaTrader 4 / MetaTrader 5 (MT4/MT5)

The standard execution platform in retail FX. Most retail brokers offer MT4 or MT5 as their trading interface. It handles order execution, position management, and basic charting. MT4 is the legacy standard; MT5 is the newer version with more asset classes and better backtesting.

What it's good for: executing trades, managing positions, running automated strategies (Expert Advisors).

What it's not: the charting is functional but nowhere near TradingView quality. Most serious traders use TradingView for analysis and MT4/MT5 for execution.

TradingView is for analysis and charting. MetaTrader is for execution. Many traders use both — analyse on TradingView, execute on MetaTrader. They serve different purposes and aren't really competitors.

News & Data

Bloomberg Terminal

The gold standard for professional financial data. Real-time pricing, news, analytics, messaging — everything a professional trader needs on one screen. Costs roughly $25,000/year. If you're working at an institution, you'll have one. If you're an independent trader, you almost certainly don't need one.

What it's good for: everything, if you can afford it.

What it's not: accessible for retail traders. The cost is prohibitive and most of its value comes from features designed for institutional workflows.

Reuters / Refinitiv Eikon

Bloomberg's main competitor in the professional terminal space. Similar capabilities, slightly different strengths (Refinitiv has strong FX data historically). Also institutional pricing. If your firm uses Reuters instead of Bloomberg, the experience is comparable.

ForexFactory

The most popular free resource for retail FX traders. Its economic calendar is the industry standard — almost every FX trader checks ForexFactory for upcoming data releases. The forums have useful threads, though signal-to-noise ratio varies.

What it's good for: economic calendar (essential), market news, community discussion.

What it's not: a substitute for proper research or analysis. Take forum opinions with skepticism.

Seeking Alpha

Primarily an equities-focused platform, but increasingly useful for macro and FX analysis. The contributor model means quality varies enormously — some articles are institutional-grade, others are clickbait. The macro section and earnings analysis can inform FX views on cross-border flows and corporate hedging patterns.

What it's good for: macro analysis, earnings context, equity-FX cross-references.

What it's not: an FX-specialist platform. Filter carefully.

Economic Data

FRED (Federal Reserve Economic Data)

Free, comprehensive, and the most reliable source for US economic data. GDP, employment, inflation, interest rates, money supply — it's all here with long time series. Essential for anyone doing macro analysis.

What it's good for: US economic data, historical time series, custom charts.

What it's not: real-time. FRED is for research and analysis, not for trading off live releases.

TradingEconomics

Global economic data covering most countries. Clean interface, easy to compare across economies. Includes forecasts and historical data. The free tier is limited but useful; paid tiers offer more data and API access.

What it's good for: comparing economic indicators across countries, getting a quick snapshot of any economy.

What it's not: as deep or reliable as going directly to source (central banks, national statistics offices).

Central Bank Websites

The primary source for monetary policy decisions, rate statements, economic projections, and meeting minutes. Bookmark the Fed (federalreserve.gov), ECB (ecb.europa.eu), BOE (bankofengland.co.uk), BOJ (boj.or.jp), and any other central bank relevant to the currencies you trade. Reading actual central bank communication is more valuable than reading other people's interpretation of it.

BIS (Bank for International Settlements)

The central bank of central banks. Publishes the Triennial Survey of FX market turnover (the source for the "$7.5 trillion daily" figure), working papers on market structure, and data on cross-border banking flows. Not for daily trading, but essential for understanding how the market actually works.

Brokers — What to Look For

We don't recommend specific brokers — the right choice depends on your location, capital, trading style, and which instruments you need. But here's what matters:

Regulation

Trade with a broker regulated by a reputable authority — FCA (UK), ASIC (Australia), CFTC/NFA (US), MAS (Singapore). Regulation doesn't eliminate risk, but it provides legal protections and ensures the broker meets capital requirements.

Execution model

Understand whether your broker is a market maker (they take the other side of your trade) or an ECN/STP (they pass your order to liquidity providers). Neither is inherently better — market makers can offer tighter spreads but have potential conflicts of interest. ECN/STP offers more transparent pricing but may charge commissions.

Spreads and commissions

Compare all-in costs, not just quoted spreads. A broker with 0.1 pip spreads and a $7 round-trip commission isn't necessarily cheaper than one with 1.2 pip spreads and no commission.

Leverage

More is not better. Most retail traders use too much leverage. The fact that a broker offers 500:1 leverage doesn't mean you should use it. Professional FX traders at banks typically operate at effective leverage of 5-10x, not 500x.

Segregated funds

Your money should be held in segregated accounts, separate from the broker's operating funds. This protects you if the broker goes bankrupt.
