Understanding financial trading terminology is crucial for anyone involved in the markets—whether you're analyzing currency pairs, reading economic reports, or interpreting technical chart patterns. This comprehensive glossary covers key terms across fundamental analysis, technical indicators, price action, market structure, and trading strategies. Designed for both beginners and experienced traders, this guide helps decode complex jargon into clear, actionable insights.
Key Market Indicators and Economic Data
Economic indicators provide vital clues about a country’s financial health and can significantly influence asset prices. Traders monitor these data releases to anticipate central bank decisions, currency movements, and broader market trends.
Non-Farm Payroll (NFP)
One of the most impactful monthly reports, NFP measures changes in U.S. employment excluding the agricultural sector. Released by the Bureau of Labor Statistics on the first Friday of each month, strong NFP figures often boost the U.S. dollar due to expectations of economic strength and potential rate hikes.
Consumer Price Index (CPI)
The CPI tracks changes in the cost of a basket of goods and services over time. It's a primary gauge of inflation. When CPI readings rise above expectations, it may signal tightening monetary policy, supporting the domestic currency.
Gross Domestic Product (GDP)
GDP reflects the total value of goods and services produced within a country over a specific period. Quarterly GDP growth rates indicate whether an economy is expanding or contracting. Sustained negative growth typically signals a recession.
Purchasing Managers' Index (PMI)
The PMI surveys executives on business conditions in manufacturing and services sectors. A reading above 50 indicates expansion, while below 50 suggests contraction. High PMI values are generally positive for the national currency.

Core Technical Analysis Concepts
Technical analysis involves studying historical price data and patterns to forecast future movements. Below are foundational elements every trader should understand.
Support and Resistance
These are price levels where buying or selling pressure tends to emerge:
- Support: A level where demand outweighs supply, preventing further decline.
- Resistance: A level where selling pressure exceeds buying interest, halting upward movement.
Breakouts above resistance or breakdowns below support often signal new trends.
Trendlines and Channels
A trendline connects consecutive highs (in downtrends) or lows (in uptrends). When paired with a parallel return line, it forms a channel, useful for identifying continuation patterns and setting profit targets.
Candlestick Patterns
Candlesticks visually represent price action over time, showing open, high, low, and close (OHLC). Common reversal patterns include:
- Bullish Engulfing: A large green candle fully engulfs the prior red candle, signaling potential upward reversal.
- Bearish Engulfing: The opposite—suggesting downside momentum.
- Doji: Indicates indecision when opening and closing prices are nearly equal.
- Hammer & Hanging Man: Both have long lower shadows; hammer forms at bottoms (bullish), hanging man at tops (bearish).
Popular Technical Indicators
Indicators help traders identify momentum, volatility, and entry/exit points.
Relative Strength Index (RSI)
Developed by Welles Wilder, RSI measures price speed and change to evaluate overbought (>70) or oversold (<30) conditions. Divergences between price and RSI can foreshadow reversals.
Moving Average Convergence Divergence (MACD)
The MACD plots the difference between two exponential moving averages (EMAs). It includes:
- MACD line (12-day EMA – 26-day EMA)
- Signal line (9-day EMA of MACD)
- Histogram (difference between MACD and signal line)
Crossovers above/below zero and divergences offer trade signals.
Average True Range (ATR)
Also developed by Wilder, ATR quantifies market volatility. Higher ATR values occur after sharp moves—often near trend reversals—while low readings suggest consolidation.
Bollinger Bands
Created by John Bollinger, these consist of:
- Middle band: Simple moving average (SMA)
- Upper/lower bands: ±2 standard deviations from SMA
Price touching upper band may indicate overbought conditions; lower band suggests oversold levels.

Advanced Chart Patterns
Beyond single candlesticks, multi-candle formations reveal deeper market sentiment.
Head and Shoulders / Inverse Head and Shoulders
- Head and Shoulders: Bearish reversal pattern with three peaks—the middle highest (“head”) flanked by two smaller “shoulders.” Break below the neckline confirms bearish momentum.
- Inverse Version: Bullish counterpart seen after downtrends.
Triangles
Three common types:
- Symmetrical Triangle: Converging trendlines suggest consolidation before breakout.
- Ascending Triangle: Flat top with rising bottom—often bullish.
- Descending Triangle: Flat bottom with lower highs—typically bearish.
Volume confirmation upon breakout increases reliability.
Flags and Pennants
Short-term continuation patterns following strong moves ("flagpole").
- Flags: Rectangular consolidation against the trend.
- Pennants: Small symmetrical triangles.
Both usually resolve in the direction of the prior trend.
Trading Mechanics and Order Types
Understanding how trades are executed ensures better control over risk and strategy.
Market Orders vs. Pending Orders
- Market Order: Executes immediately at current price.
Pending Orders:
- Buy Limit: Set below current price.
- Sell Limit: Set above current price.
- Buy Stop: Above market—triggers bullish entry if breakout occurs.
- Sell Stop: Below market—used for short entries on breakdowns.
Leverage and Margin
Leverage allows traders to control larger positions with less capital (e.g., 1:100). While it amplifies gains, it also increases risk. Margin is the required deposit to maintain open leveraged positions.
Stop-Loss and Take-Profit
Essential risk management tools:
- Stop-Loss: Closes losing trades automatically.
- Take-Profit: Locks in profits at predefined levels.
Frequently Asked Questions (FAQ)
What is a pip in forex trading?
A pip (percentage in point) is the smallest price move in a currency pair. For most pairs, one pip equals 0.0001 (e.g., EUR/USD moving from 1.0850 to 1.0851). JPY pairs use 0.01 as one pip.
How do support and resistance levels form?
They emerge from repeated price reactions at certain levels—often tied to psychological numbers, previous highs/lows, or volume clusters. The more times price tests a level without breaking it, the stronger it becomes.
Can technical analysis predict market movements accurately?
While not foolproof, technical analysis improves probability-based decision-making. Success depends on combining multiple tools—indicators, patterns, volume—and managing risk appropriately.
What is the difference between leading and lagging indicators?
Leading indicators (like RSI or Stochastic) attempt to predict future moves but may give false signals. Lagging indicators (such as moving averages) confirm trends after they’ve started but reduce whipsaw risk.
Why is risk management important in trading?
Markets are inherently uncertain. Proper risk controls—position sizing, stop-loss orders, diversification—protect capital during losing streaks and ensure long-term sustainability.
How do economic events affect currency values?
Data like NFP, CPI, or GDP influence central bank policies. Strong data may lead to rate hikes, boosting the currency; weak data can trigger dovish shifts, weakening it.
