Use the A–Z navigation above to jump to any term. Terms are grouped alphabetically below with plain-English explanations and practical examples. New traders should start with the Market Basics and Account Terms sections before moving to more advanced concepts.
A
Ask Price (Offer)The price at which you can buy a currency pair. In EUR/USD quoted at 1.0850/1.0852, the ask is 1.0852. The difference between the bid and ask is the spread — your transaction cost on every trade.
At the MarketAn instruction to execute a trade immediately at the best available current price. Also called a market order. There is no guaranteed execution price — the final fill price may differ slightly from the quoted price, especially during fast markets (slippage).
Automated Trading / EA (Expert Advisor)A computer programme that executes trades automatically based on pre-programmed rules. EAs run on platforms like MetaTrader 4 and 5. They remove emotional decision-making but require thorough testing before deployment on live accounts.
B
BalanceThe total monetary value in your trading account excluding any open trade profit or loss. If your account shows Rs 50,000 with no open trades, your balance is Rs 50,000. Contrast with equity, which includes floating P&L from open positions.
Base CurrencyThe first currency in a currency pair. In EUR/USD, the euro (EUR) is the base currency. The exchange rate tells you how many units of the quote currency are needed to buy one unit of the base currency.
Bear MarketA sustained downward trend in a currency or market. A bearish trader expects prices to fall and takes short positions. Opposite of a bull market.
Bid PriceThe price at which you can sell a currency pair. In EUR/USD quoted at 1.0850/1.0852, the bid is 1.0850. When you open a sell trade, you get filled at the bid price.
BreakoutWhen price moves decisively through a support or resistance level that had previously contained it. Breakouts often signal the start of a new directional trend and are a popular entry signal for many trading strategies.
Bull MarketA sustained upward trend in a currency or market. A bullish trader expects prices to rise and takes long positions. Strong economic data, rising interest rates, or positive sentiment typically drive bull markets.
CandlestickA price chart format showing the open, high, low, and close for a specific time period as a rectangular “candle.” A bullish candle (usually white or green) closes higher than it opened. A bearish candle (usually black or red) closes lower than it opened. The wicks (thin lines above and below the body) show the high and low extremes.
Carry TradeA strategy that profits from the interest rate differential between two currencies. You borrow in a low-interest-rate currency (e.g., Japanese yen) and invest in a high-interest-rate currency, earning the difference as a daily swap credit. The risk: a sudden reversal of the higher-yielding currency can wipe out carry income.
Central BankThe government-controlled institution responsible for a country’s monetary policy, interest rate decisions, and currency supply. Examples: Federal Reserve (US), European Central Bank (ECB), Bank of England (BoE), Reserve Bank of India (RBI). Central bank decisions are the most powerful fundamental drivers of currency price movements.
CPI (Consumer Price Index)A measure of inflation tracking the price changes of a basket of consumer goods and services. Higher CPI than expected typically signals the need for higher interest rates (bullish for the currency). Lower CPI signals the opposite.
Cross Currency PairA currency pair that does not include the US dollar. Examples: EUR/GBP, EUR/JPY, GBP/JPY, AUD/NZD. Cross pairs typically have wider spreads and lower liquidity than major USD pairs.
Currency PairThe quotation of one currency relative to another. Every forex trade involves simultaneously buying one currency and selling another. Written as a two-currency combination: EUR/USD (euro vs US dollar), GBP/USD (pound vs dollar), USD/JPY (dollar vs yen).
D
Day TradingA trading style where all positions are opened and closed within the same trading day — no positions held overnight. Day traders avoid overnight swap charges and weekend gap risk. Requires active monitoring during trading hours and works best during high-liquidity sessions.
Demo AccountA practice trading account using virtual money but live market prices and execution. Demo accounts allow traders to test strategies and learn platform mechanics without financial risk. Essential for at least 30 days before trading with real money.
DrawdownThe peak-to-trough decline in an account’s value during a specific period. A 20% drawdown means the account fell from its peak value to a point 20% lower before recovering. Maximum drawdown is the largest decline experienced over the entire trading history — a critical risk metric for evaluating any strategy or signal service.
E
ECN (Electronic Communication Network)A broker model that connects traders directly to other market participants and liquidity providers, displaying real interbank prices. ECN brokers charge a commission per trade but offer tighter spreads (sometimes 0.0 pips raw) and no conflict of interest between broker and trader.
EquityYour account balance plus or minus any floating profit or loss from open positions. If your balance is Rs 50,000 and you have an open trade with a Rs 2,000 unrealised profit, your equity is Rs 52,000. Margin calls are triggered based on equity, not balance.
Exchange RateThe price at which one currency can be exchanged for another. In EUR/USD = 1.0850, one euro costs 1.0850 US dollars. Exchange rates fluctuate continuously based on supply and demand, economic data, and geopolitical events.
Exotic Currency PairA pair combining a major currency with a currency from a smaller or emerging market economy. Examples: USD/INR, USD/TRY, USD/ZAR, EUR/MXN. Exotic pairs have very wide spreads (sometimes 20–50 pips) and lower liquidity, making them unsuitable for most retail trading strategies.
F
Fibonacci RetracementA technical analysis tool identifying potential support and resistance levels based on Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%). Traders use these levels to identify potential pullback zones within a trend and plan entry points.
FOMC (Federal Open Market Committee)The committee within the US Federal Reserve that sets interest rate policy. FOMC meetings occur 8 times per year and their decisions on the federal funds rate are among the most market-moving scheduled events in forex. EUR/USD and USD pairs can move 100–300 pips around FOMC announcements.
Free MarginThe amount of equity in your account not currently committed as margin for open trades. Calculated as: Equity minus Used Margin. Free margin represents the capital available to open new positions. When free margin reaches zero, no new trades can be opened.
Fundamental AnalysisEvaluating currency price movements based on economic, political, and financial factors rather than price charts. Fundamental analysts study interest rates, inflation, GDP growth, employment data, and central bank policy to forecast currency direction.
G
GapA price jump where a currency opens significantly higher or lower than where it closed in the previous session. Gaps occur on Monday morning openings (when the market reopens after the weekend) or around major news events. Gap risk is why day traders typically close all positions before the weekend market close.
GDP (Gross Domestic Product)The total monetary value of all goods and services produced within a country in a specific period. GDP is a primary measure of economic strength. Above-expectation GDP figures typically strengthen the country’s currency as they signal economic growth that may support higher interest rates.
H
Hedge / HedgingOpening a position that reduces the risk of an existing position. Example: if you hold a long EUR/USD position and want temporary protection, you open a short EUR/USD position to offset the risk. Hedging reduces potential loss but also limits potential profit. Some brokers restrict hedging on the same account.
High / Low (of a Session or Candle)The highest and lowest price reached during a specific time period. Session highs and lows (daily, weekly) act as natural support and resistance levels. Breaking a session high with strong volume often signals continuation in that direction.
I
Indicator (Technical)A mathematical calculation based on historical price and/or volume data, plotted on or below a price chart to help identify trends, momentum, or potential reversals. Common examples: moving averages, RSI, MACD, Bollinger Bands, Stochastic. Indicators are lagging (based on past data) and should be used as confirmation tools, not standalone signals.
Interest RateThe cost of borrowing money, set by central banks. Higher interest rates typically attract foreign investment seeking better returns, strengthening the currency. Lower interest rates reduce the currency’s appeal to carry traders, weakening it. Interest rate differentials between countries are the primary fundamental driver of long-term currency trends.
J
Japanese Yen (JPY)The currency of Japan, the world’s third-largest economy. JPY is considered a “safe haven” currency — when global risk sentiment deteriorates, investors sell higher-yielding assets and buy yen, typically causing USD/JPY and other JPY crosses to fall sharply. Japan’s central bank is the Bank of Japan (BoJ).
K
KYC (Know Your Customer)The identity and address verification process that regulated brokers must complete before allowing withdrawals. Typically requires a government-issued ID (passport, driving licence, Aadhaar) and proof of address (bank statement or utility bill). Completing KYC immediately after account opening prevents withdrawal delays later.
L
LeverageThe ability to control a position larger than your actual deposit. At 1:100 leverage, Rs 1,000 in your account controls a Rs 1,00,000 position. Leverage amplifies both profits and losses. A 1% move against a 1:100 leveraged position wipes out the full margin. For a deep dive on how leverage works and how to use it safely, see our complete guide to forex leverage with examples and risk calculations.
Limit OrderAn order to buy or sell at a specified price or better. A buy limit is placed below the current price (you want to buy cheaper). A sell limit is placed above the current price (you want to sell higher). Limit orders are used to enter trades at specific planned price levels without needing to monitor the market constantly.
LiquidityThe ease with which an asset can be bought or sold without significantly affecting its price. Forex is the most liquid market in the world, with $7.5 trillion traded daily. High liquidity means tight spreads, fast execution, and minimal slippage. Liquidity is highest during the London–New York overlap (1:00–5:00 PM GMT).
Long Position (Going Long)Buying a currency pair, expecting its price to rise. If you buy EUR/USD at 1.0850 and it rises to 1.0900, you profit 50 pips. Going long means you are bullish on the base currency relative to the quote currency.
LotThe standard unit of measurement for forex trade sizes. One standard lot = 100,000 units of the base currency. One mini lot = 10,000 units (0.1 lot). One micro lot = 1,000 units (0.01 lot). For EUR/USD, 1 pip on 1 standard lot = approximately $10. On 0.1 lot, 1 pip = approximately $1. Using lot sizes that match your risk tolerance is fundamental to safe trading.
Core Forex Concepts — How Bid, Ask, Spread, Pip, and Lot Connect
The bid price is where you sell; the ask is where you buy. The spread (ask minus bid) is your transaction cost paid on every trade entry. Pip is the smallest price move unit. Lot size determines your pip value in rupees and is calculated from your risk budget, not chosen arbitrarily.
M
MACD (Moving Average Convergence Divergence)A momentum indicator showing the relationship between two moving averages (typically 12-period and 26-period EMAs). A buy signal occurs when the MACD line crosses above the signal line; a sell signal when it crosses below. Divergence between MACD and price can signal potential trend reversals.
Major Currency PairsThe most heavily traded currency pairs globally, all including the US dollar. The seven majors: EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD, NZD/USD. Majors have the tightest spreads and highest liquidity of all currency pairs.
MarginThe deposit required to open and maintain a leveraged position. At 1:100 leverage on a 1 standard lot EUR/USD trade (worth ~$108,500), the margin requirement is approximately $1,085. Margin is not a fee — it is collateral held while the position is open and returned (plus or minus P&L) when closed.
Margin CallA warning from your broker that your account equity has fallen below the required margin level (typically 100% margin level). At this point, you must either deposit more funds or close positions to restore the required margin. If equity falls further to the stop-out level (often 50% margin level), the broker automatically closes positions to prevent further losses.
Market MakerA broker that takes the opposite side of client trades internally, profiting from the spread. Market makers set their own bid/ask prices and act as counterparty to client orders. Because they profit when clients lose, there is an inherent conflict of interest. However, regulated market makers are subject to strict oversight preventing price manipulation.
Market OrderAn instruction to buy or sell immediately at the best available current market price. The order executes instantly but the fill price may differ slightly from the quoted price (slippage), especially during news events or thin market hours.
MetaTrader 4 / MetaTrader 5 (MT4 / MT5)The world’s most widely used retail forex trading platforms, developed by MetaQuotes Software. Both offer charting tools, automated trading via Expert Advisors, and connection to most retail forex brokers. MT5 supports more order types and can trade stocks and futures in addition to forex.
Moving AverageA technical indicator that smooths price data by calculating the average price over a specified number of periods. A 200-period moving average on a daily chart is widely used to identify the long-term trend direction — price above the 200 MA is considered bullish; below is bearish.
N
NFP (Non-Farm Payrolls)The monthly US employment report showing jobs added or lost outside the agricultural sector. Released on the first Friday of each month at 8:30 AM EST (7:00 PM IST). NFP is the single most market-moving scheduled event in forex — a large surprise can move EUR/USD 100–200 pips within minutes.
Notional ValueThe total value of a leveraged position before the leverage is applied. A 1 standard lot EUR/USD at 1.0852 has a notional value of approximately $108,520. Understanding notional value helps clarify the actual risk exposure of your leveraged trades.
O
OHLC (Open, High, Low, Close)The four price points that define each candlestick or price bar: the opening price, the highest price reached, the lowest price reached, and the closing price for the period. OHLC data is the foundation of all technical chart analysis.
Order (Trade Order)An instruction sent to your broker to execute a trade. Order types include market orders (execute immediately), limit orders (execute at a specified price or better), stop orders (execute when price reaches a specified level), and pending orders (conditional orders that activate only when a trigger price is reached).
OscillatorA technical indicator that fluctuates between fixed values (such as 0–100) to identify overbought and oversold conditions. Common oscillators: RSI (Relative Strength Index), Stochastic Oscillator, CCI (Commodity Channel Index). When an oscillator reaches an extreme level (RSI above 70 or below 30), it signals potential reversal zones.
Over-the-Counter (OTC)Trading that occurs directly between parties through a dealer network rather than on a centralised exchange. Forex is the world’s largest OTC market. The decentralised nature means prices can differ slightly between brokers and there is no single official exchange price at any moment.
P
Pending OrderAn order placed in advance to execute automatically when price reaches a specified level. The four types: Buy Limit (buy when price falls to a lower level), Sell Limit (sell when price rises to a higher level), Buy Stop (buy when price rises to a higher level — breakout entry), Sell Stop (sell when price falls to a lower level).
Pip (Percentage in Point)The smallest standardised price movement in a currency pair. For most pairs, 1 pip = 0.0001 (the 4th decimal place). For JPY pairs, 1 pip = 0.01 (the 2nd decimal place). EUR/USD moving from 1.0850 to 1.0860 is a 10-pip move. Pip value in your account currency depends on your lot size. For the full explanation with worked examples, see our complete guide to what pips are in forex and how to calculate their value in rupees.
PMI (Purchasing Managers’ Index)A monthly survey of business activity in manufacturing and services sectors. A reading above 50 signals expansion; below 50 signals contraction. PMI is a leading economic indicator — it anticipates GDP growth before the actual GDP figure is released.
Position SizeThe number of lots (or units) traded in a specific trade. Position size should always be calculated based on your risk percentage and stop loss distance — not chosen arbitrarily. Correct position sizing is the most important mechanical element of risk management.
Q
Quote CurrencyThe second currency in a currency pair. In EUR/USD, the US dollar (USD) is the quote currency. The exchange rate tells you how many units of the quote currency are needed to buy one unit of the base currency. Your account P&L is typically expressed in the quote currency.
R
Range TradingA strategy that profits from sideways price movement by buying at the bottom of an established range (support) and selling at the top (resistance). Works best when markets are in consolidation and no strong directional trend is present.
RequoteWhen a broker rejects your market order at the quoted price and offers a new (usually worse) price instead. Requotes typically occur with market maker brokers during fast markets or around news events. ECN brokers generally do not requote — orders fill at the available market price or not at all.
Resistance LevelA price level where selling pressure has historically been strong enough to prevent further price rises. Price approaching a resistance level from below is expected to slow, pause, or reverse. Broken resistance often becomes new support.
Risk-to-Reward Ratio (R:R)The ratio of the potential loss (risk) to the potential gain (reward) on a trade. A trade risking 20 pips to gain 40 pips has a 1:2 risk-to-reward ratio. Most professional traders maintain a minimum 1:1.5 to 1:2 R:R to ensure profitability even with a sub-50% win rate.
RolloverThe process of extending the settlement of an open position to the next business day. When you hold a position overnight, your broker credits or debits a swap amount based on the interest rate differential between the two currencies in the pair. See also: Swap.
RSI (Relative Strength Index)A momentum oscillator measuring the speed and change of price movements on a scale of 0–100. RSI above 70 is considered overbought (potential for a pullback); RSI below 30 is considered oversold (potential for a bounce). RSI divergence from price can signal trend reversals.
S
ScalpingA high-frequency trading style targeting very small profits (1–10 pips) on a large number of trades per day. Scalping requires extremely tight spreads, fast execution, and the highest-liquidity trading sessions (London–New York overlap). Unsuitable for brokers with wide spreads or significant slippage.
Short Position (Going Short)Selling a currency pair, expecting its price to fall. If you sell EUR/USD at 1.0850 and it falls to 1.0800, you profit 50 pips. Going short means you are bearish on the base currency relative to the quote currency.
SlippageThe difference between the expected execution price of an order and the actual price at which it fills. Slippage occurs during fast market conditions (news releases, market opens) when prices move so quickly that the quoted price is no longer available by the time the order is processed. Slippage can be positive (you get a better price than expected) or negative (worse price).
SpreadThe difference between the bid (sell) and ask (buy) price. The spread is your transaction cost on every trade. EUR/USD at 1.0850/1.0852 has a 2-pip spread. Tighter spreads reduce trading costs. ECN brokers typically offer the tightest spreads (as low as 0.0–0.3 pips during peak hours) but charge a separate commission.
STP (Straight Through Processing)A broker execution model that automatically routes client orders directly to liquidity providers without a dealing desk intervening. STP brokers do not take the opposite side of client trades (unlike market makers), reducing potential conflicts of interest.
Support LevelA price level where buying pressure has historically been strong enough to prevent further price declines. Price approaching a support level from above is expected to slow, pause, or reverse upward. Broken support often becomes new resistance.
Swap (Overnight Interest)The interest rate differential paid or received when a forex position is held open overnight. If you are long a higher-yielding currency, you typically receive a positive swap credit. If you are long a lower-yielding currency, you pay a negative swap debit. Swap rates vary by broker and pair and are published in the broker’s contract specifications.
Swing TradingA medium-term trading style holding positions for 1–5 days to capture multi-day directional moves. Swing traders focus on daily and 4-hour charts, use wider stop losses than day traders, and are less sensitive to session timing. Suitable for traders who cannot monitor markets continuously during the day.
T
Take Profit (TP)A predetermined price level at which a profitable trade automatically closes to lock in gains. Setting a take profit removes the emotion from the exit decision and ensures you secure profits when your target is reached, even if you are not watching the market.
Technical AnalysisThe study of historical price charts and trading volume to forecast future price direction. Technical analysts believe that all relevant information is already reflected in the price, and patterns on charts tend to repeat. Key tools: candlestick patterns, support/resistance, moving averages, RSI, MACD, Fibonacci levels.
Trailing StopA stop loss that automatically moves in the direction of a profitable trade, locking in gains as the trade moves in your favour. If EUR/USD rises 30 pips and your trailing stop is set to 20 pips, the stop moves up 30 pips and now sits 20 pips below the current price. If the trade reverses, the stop closes the position at the locked-in level.
TrendThe general direction of price movement over a period. An uptrend shows consistently higher highs and higher lows. A downtrend shows lower highs and lower lows. Trading in the direction of the primary trend is the most fundamental risk management principle in technical trading.
U
Unrealised P&L (Floating P&L)The profit or loss on open positions that has not yet been locked in by closing the trade. Unrealised gains and losses affect your equity in real time but do not impact your balance until the trade is closed.
V
VolatilityThe degree of price variation over time. High volatility means price is moving sharply in both directions. Low volatility means price is relatively stable. Volatility affects stop loss placement (wider stops needed in volatile markets), spread width, and slippage risk. News events typically spike volatility dramatically.
VolumeThe number of units traded in a given period. In the OTC forex market, true volume data is not available because there is no centralised exchange. Brokers publish tick volume (the number of price changes per period) as a proxy. Volume analysis on forex is therefore less precise than on stock exchanges.
W
WhipsawA rapid price reversal that catches traders on the wrong side of a breakout. Price briefly breaks a key level, triggering entry orders, then immediately reverses. Whipsaws are common during thin-volume periods and immediately before high-impact news releases. Waiting for candle close confirmation rather than entering on initial breakout reduces whipsaw risk.
Win RateThe percentage of trades that close profitably. A 60% win rate means 6 out of every 10 trades are winners. Win rate alone does not determine profitability — a strategy with a 40% win rate can still be profitable if average wins are significantly larger than average losses (high risk-to-reward). The combination of win rate and R:R determines long-term expectancy.
X, Y, Z
XAU/USD (Gold vs US Dollar)Gold is traded as a currency pair against the US dollar in forex markets. XAU is the ISO code for gold (from the Latin aurum). Gold is considered a safe-haven asset and often rises when US dollar or global risk sentiment weakens. It is one of the most actively traded commodities on forex platforms.
Yield (Currency Yield / Interest Rate)The return generated by holding a currency, determined by the country’s prevailing interest rate. Higher-yielding currencies attract carry trade investment. The yield differential between two countries is a primary driver of the long-term trend in their currency pair.
Zero BalanceWhen an account’s equity reaches zero, typically after all positions have been automatically closed by a margin call stop-out. Most regulated brokers offer negative balance protection — meaning your account cannot fall below zero and you cannot owe the broker money beyond your deposit.
Order Types Explained — When to Use Each
Every professional trader uses a combination of these order types on every trade: a market or limit order for entry, a stop loss to limit downside, and a take profit or trailing stop for the exit. Never enter a trade with only one order type — always have entry, stop, and target planned before execution.
Frequently Asked Questions — Forex Glossary
The five most important terms for any new forex trader to understand before their first trade are: (1) Pip — the unit of price movement that determines your profit or loss. Without understanding pips, you cannot calculate position sizes or assess risk. (2) Spread — your transaction cost on every trade. Wide spreads require larger price moves to become profitable. (3) Leverage — the amplification factor that makes both gains and losses larger than your deposit. Misuse of leverage is the single most common cause of beginner account losses. (4) Margin / Margin Call — understanding what collateral your broker holds and at what point they can automatically close your positions. (5) Stop Loss — the mechanism that limits your maximum loss on any single trade. Trading without stop losses is the fastest way to lose your entire account in a single adverse move.
A pip is the fourth decimal place in most currency pairs (0.0001). A pipette (or fractional pip) is the fifth decimal place (0.00001) — one-tenth of a pip. Many brokers now display five decimal places to provide more precise pricing. When a broker quotes EUR/USD at 1.08504, that final 4 is a pipette. Pip values are always calculated based on the 4th decimal (or 2nd decimal for JPY pairs), regardless of whether pipettes are displayed. For practical purposes, think in pips — pipettes are just for more granular pricing.
Going long means buying a currency pair, expecting the price to rise. You profit if the pair moves up after your purchase. Going short means selling a currency pair, expecting the price to fall. You profit if the pair moves down after your sale. Forex uniquely allows traders to profit in both rising and falling markets by going long or short respectively. When you go short, you are borrowing the base currency from your broker to sell it, then buying it back at a lower price to return it and pocket the difference. This happens seamlessly through your trading platform without you needing to manage the actual currency lending process.
A swap charge (also called a rollover or overnight interest) is the amount credited or debited to your account when you hold a position open overnight. It reflects the interest rate differential between the two currencies in the pair. If you are long a currency with a higher interest rate than the currency you are short, you typically receive a positive swap (credit). If you are long a lower-yielding currency, you pay a negative swap (debit). Swap charges are small relative to pip movements on any single day, but they compound over time for positions held for weeks or months. Traders holding positions for long periods should check the swap rate before committing, as negative swaps erode profitability over time. Most broker platforms display swap rates in the contract specifications for each instrument.
A margin call occurs when your equity falls below your broker’s required margin percentage (typically 100% margin level). Here is an example: you deposit Rs 10,000 and open a EUR/USD trade using Rs 2,000 in margin. If the trade moves against you and your equity falls to Rs 2,000 (100% of the Rs 2,000 required margin), your broker issues a margin call warning. At this point you can either deposit more funds to restore your margin or close positions to free up margin. If you do nothing and equity continues falling to the stop-out level (often 50% margin level — Rs 1,000 in this example), your broker automatically closes your position. This automatic close-out protects both you and the broker from negative balances. Prevention: maintain sufficient free margin by risking only 1–2% per trade and never over-leveraging your account.
