Technical Analysis Terms

Accumulation in trading refers to the phase in which large institutional buyers (funds, banks, large speculators) quietly build significant long positions in a currency or asset, typically during a period of sideways or compressed price action that disguises their activity. The accumulation phase precedes a significant upward move when the institutional buying is complete and retail participation follows.

The Accumulative Swing Index (ASI) is a trend-following momentum oscillator developed by J. Welles Wilder Jr. that aggregates daily Swing Index values across open, high, low, and close prices to identify phantom breakouts and true directional trendline breaks.

The Advance-Decline Line (A/D Line) is a cumulative market breadth indicator that measures the net difference between the number of advancing and declining securities each day. It reveals the underlying participation and internal health of a financial market beneath headline index levels.

Andrews' Pitchfork is a technical analysis charting tool developed by Dr. Alan Andrews that uses three consecutive swing pivots to project a central median line flanked by two equidistant parallel lines. It serves as a dynamic channel to forecast support, resistance, and price targets.

The mathematical measure of the degree of correlation between values of the same variable across successive time intervals. In financial markets, autocorrelation quantifies whether asset returns exhibit serial dependency—such as momentum persistence or mean-reversion—providing critical empirical inputs for quantitative modeling and algorithmic trading systems.

A bar chart in forex is a price chart that displays price action using vertical bars, where each bar represents a specific time period (minute, hour, day, week). Each bar shows four data points: the open price, close price, high, and low of the period. Bar charts are one of the three most common chart types in technical analysis, alongside line charts and candlestick charts.

Bollinger Bands are a volatility indicator consisting of three lines plotted on a price chart: a 20-period simple moving average in the center, and upper and lower bands set at two standard deviations above and below it. Created by John Bollinger in the 1980s, they expand during high volatility and contract during low volatility.

A technical analysis and order flow trading concept describing the market dynamic where the decisive breach of a primary support or resistance level triggers a rapid, cascading price movement toward the next sequential structural price barrier.

A breakaway gap is a high-momentum technical chart pattern where an asset's price jumps violently past a major support or resistance boundary, leaving an unfilled void on the price chart. It signals the decisive end of a consolidation phase and the birth of a powerful new trend.

A breakout occurs when price moves decisively beyond a defined support, resistance, trend line, or chart pattern boundary. It signals that the balance of buying and selling pressure has shifted — supply or demand that previously contained price has been overcome. Breakouts are among the most widely traded signals in forex technical analysis, offering clear entry signals with defined risk.

A calendar effect is an empirical anomaly in financial markets where asset prices and returns exhibit systematic, statistically significant patterns or seasonal deviations correlated with specific calendar periods, days of the week, or months.

A candlestick chart displays four key price points for each time period — open, high, low, and close — using a visual 'candle' body and wicks. Developed in 18th-century Japan by rice traders, it remains the dominant chart type in modern forex and stock markets.

A channel is a price pattern formed by two parallel trend lines that contain price movement — an upper line connecting swing highs and a lower line connecting swing lows. Channels can slope upward (ascending channel, bullish), downward (descending channel, bearish), or move horizontally (ranging channel). They provide clear, structural boundaries for both support and resistance trading and are among the most visually intuitive patterns in technical analysis.

Financial market participants who rely primarily on graphical price charts, geometric formations, candlestick patterns, and mathematical indicators to analyze market psychology, identify emerging trends, and execute trading strategies.

A continuation (trend continuation) in technical analysis refers to the resumption of an established primary trend following a period of consolidation, pause, or counter-trend retracement, often validated by classic chart patterns.

A correction is a price decline of 10% to 20% from a recent peak in financial markets, or a substantial counter-trend retracement in currency trading that temporarily offsets an overextended directional trend before resuming or reversing.

Cover on a bounce is a reactive technical exit strategy where a short seller holds their position through a test of major support, liquidating (covering) only after price confirms an upward rejection or bounce.

Cover on approach is a proactive technical execution strategy where a short seller liquidates (covers) their position as price nears a major support level, securing profits before potential front-running or reversal bounces occur.

A cup with handle (cup and handle) is a classic bullish technical continuation chart pattern where an asset forms a rounded 'U-shaped' consolidation followed by a slight downward-drifting handle before breaking out.

A daily chart is a financial price chart where each individual candlestick or bar summarizes exactly one complete 24-hour trading session, encapsulating the period's Open, High, Low, and Close (OHLC) values.

The daily high is the highest market price achieved by a financial instrument during a 24-hour trading session, representing the peak boundary of buyer momentum and resistance before sellers intervened.

The daily low is the lowest market price reached by an asset during a trading day, representing the maximum extent of selling pressure and the inflection point where buying liquidity halted the decline.

A descending triangle is a bearish technical chart pattern defined by a flat horizontal support level at the bottom and a descending upper trend line connecting lower swing highs. It reflects persistent selling pressure steadily eroding buyer support, typically culminating in a downward breakout.

Divergence is a technical analysis pattern that occurs when the price of an asset and a technical momentum indicator (such as RSI, MACD, or Stochastic) move in opposite directions. It signals that the prevailing price trend is losing underlying momentum, foreshadowing a potential reversal or continuation.

Double top and double bottom are reversal chart patterns formed when price tests a significant level twice and fails to break through, signaling that the dominant trend is losing momentum. The double top (two peaks at roughly the same level) is a bearish reversal signal; the double bottom (two troughs at the same level) is a bullish reversal signal. Both are among the most reliable and widely traded reversal patterns.

Dow Theory is a foundational technical analysis framework developed by Charles Dow, positing that market prices reflect all available information, trends exist across three distinct timeframes, and primary movements unfold through accumulation, public participation, and distribution phases.

Elliott Wave Theory is a technical analysis framework positing that market price action advances and corrects in repetitive, fractal wave structures governed by shifts in collective human crowd psychology, organized into five motive waves and three corrective waves.

Moving Average Envelopes are technical overlay bands plotted at fixed percentage distances above and below a baseline moving average, establishing dynamic support and resistance channels to identify overbought and oversold market conditions.

An exponential moving average (EMA) is a technical trend indicator that places greater mathematical weight and significance on the most recent price data points, reducing lag and responding faster to price shifts than a simple moving average.

In technical analysis and Smart Money Concepts (SMC), a Fair Value Gap (FVG) is a three-candlestick market structure pattern resulting from aggressive institutional displacement that leaves a unilateral price inefficiency or liquidity imbalance between the wicks of the first and third candles.

A fakeout is a false breakout where the price of an asset momentarily moves past a recognized technical support or resistance level, triggering stop orders and trapping breakout traders before swiftly reversing direction.

Fibonacci numbers are a mathematical sequence where each number is the sum of the two preceding ones: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34... The ratios between these numbers — particularly 61.8%, 38.2%, and 23.6% — appear consistently in financial markets as retracement and extension levels that traders use to identify potential support, resistance, and price targets.

Flags and pennants are short-term continuation chart patterns that form after a sharp, near-vertical price move (the 'flagpole'). They represent a brief consolidation before the trend resumes in the same direction. The flag is a rectangular consolidation sloping slightly against the prior trend; the pennant is a small symmetrical triangle. Both are among the most reliable and cleanest continuation patterns in technical analysis.

A golden cross is a bullish technical chart pattern occurring when a short-term moving average (typically the 50-day SMA) crosses above a long-term moving average (typically the 200-day SMA), signaling the potential inception of a long-term bull market.

The Head and Shoulders pattern is one of the most reliable reversal formations in technical analysis. It consists of three peaks: a left shoulder, a higher central peak (the head), and a right shoulder matching the left's height. A break below the neckline — the trendline connecting the pattern's troughs — signals the completion of the bearish reversal.

High/low refers to the maximum and minimum market execution prices recorded for a currency pair or financial asset across a specified timeframe, establishing the trading range and defining volatility boundaries for technical analysis.

Ichimoku Kinko Hyo — meaning 'one glance equilibrium chart' in Japanese — is a comprehensive technical analysis indicator that displays trend direction, momentum, support/resistance, and potential price targets simultaneously. Developed by journalist Goichi Hosoda in the late 1930s and published in 1969, it consists of five lines and the 'cloud' (Kumo) between two of them, giving traders a complete picture of market structure at a glance.

The Kijun line, or Kijun-sen, is the 26-period base line within the Ichimoku Kinko Hyo charting system, calculated as the midpoint between the 26-period highest high and lowest low to identify medium-term trend direction, dynamic support, and market equilibrium.

A lagging indicator is a technical or macroeconomic metric that trails price action or economic performance, changing only after a significant trend or structural shift has already been established.

A line chart is a foundational graphical representation of price action created by connecting a chronological series of single data points—almost exclusively closing prices—with a continuous line segment, filtering out intra-period volatility to emphasize primary market trends.

MACD is a trend-following momentum indicator that shows the relationship between two exponential moving averages of price — typically the 12-period and 26-period EMA. The MACD line, signal line, and histogram together identify trend direction, momentum shifts, and potential entry points.

The MACD histogram is a visual technical indicator that plots the mathematical spread between the MACD line and its signal line, giving traders early warnings of momentum acceleration, deceleration, and impending trend reversals.

Mean reversion is a financial and statistical theory suggesting that asset prices, exchange rates, and volatility metrics eventually return to their historical average or baseline level after experiencing extreme deviations.

A moving average smooths price data by calculating the average closing price over a specified number of periods, updating with each new bar. It filters out short-term noise to reveal the underlying trend direction. The two main types — simple (SMA) and exponential (EMA) — differ in how they weight recent vs. older data.

The Moving Average Convergence Divergence (MACD) is a classic trend-following momentum oscillator that displays the mathematical relationship between two exponential moving averages of an asset's price, generating trade signals via line crossovers, centerline breaches, and divergences.

A negative or bearish divergence occurs when an asset's market price reaches a higher high while a momentum oscillator (such as RSI or MACD) forms a lower high, indicating underlying buyer exhaustion and warning of an impending downward reversal.

Noise—or market noise—refers to the chaotic, short-term price fluctuations and random order-flow distortions that occur without fundamental catalysts, obscuring underlying structural trends.

Odd-lot theory is a technical analysis and behavioral finance sentiment indicator based on the contrarian premise that small, unsophisticated retail investors (historically identified by transactions of fewer than 100 shares) are systematically wrong in their market timing at major inflection points.

An oscillator is a technical analysis indicator that fluctuates within a bounded numerical range or across a zero centerline to measure price momentum, velocity, and acceleration, primarily utilized to detect overbought and oversold market extremes and momentum divergences.

Overbought describes a market condition in which an asset's price has experienced a rapid, sustained, and mathematically extreme upward advance without meaningful consolidation, pushing momentum oscillators into upper statistical thresholds and indicating heightened vulnerability to a price pullback or consolidation.

Oversold describes a market condition where an asset's price has suffered a rapid, persistent, and mathematically extreme decline without intermediate consolidation, pushing technical momentum oscillators into lower statistical thresholds and indicating that selling momentum is overextended and vulnerable to a corrective bounce or trend reversal.

The Parabolic Stop and Reverse (SAR) is a technical indicator developed by J. Welles Wilder Jr. that places a trailing price envelope above or below market action, identifying trend direction and signaling potential exit or reversal points.

A Point and Figure (P&F) chart is a non-time-based technical charting method that filters out minor market noise by plotting price movements using columns of alternating X's (for rising prices) and O's (for falling prices), advancing only when price changes by a predefined box size.

The Put/Call Ratio (PCR) is a widely monitored market sentiment indicator calculated by dividing the aggregate trading volume or open interest of put options by call options over a given period, utilized primarily as a contrarian gauge to identify market extremes of fear and greed.

In financial trading, range refers to: (1) the mathematical difference between the highest and lowest price reached by an asset over a specified time interval; or (2) a sideways market structure where price oscillates horizontally between established support and resistance boundaries.

In technical analysis and market dynamics, a reaction (or reaction pullback) is a temporary, counter-trend price retracement that interrupts an established primary market trend following an extended directional advance or immediately after a high-impact macroeconomic catalyst.

A rectangle is a classic technical analysis chart pattern characterized by horizontal parallel support and resistance trendlines bounding price action, signaling a temporary pause or consolidation before price breaks out in either a trend continuation or reversal.

The Relative Strength Index (RSI) is a momentum oscillator developed by J. Welles Wilder Jr. in 1978. It measures the speed and magnitude of recent price changes on a scale of 0 to 100, helping traders identify overbought conditions (above 70), oversold conditions (below 30), and momentum divergences.

Resistance is a price level or zone on a chart where selling pressure has historically been sufficient to prevent price from rising further. It forms where sellers consistently outnumber buyers at a specific price range, creating a ceiling that price struggles to break through. When resistance is broken convincingly, it often transforms into support — a concept known as role reversal.

A reversal is a definitive change in the primary directional trend of an asset's price—transitioning from an established uptrend into a downtrend (bearish reversal) or from a downtrend into an uptrend (bullish reversal)—characterized by a structural shift in swing highs and swing lows.

Classical technical reversal chart patterns characterizing a gradual, multi-session transition in market control from buyers to sellers (rounding top) or from sellers to buyers (rounding bottom), identified by a parabolic price curve and a corresponding U-shaped volume profile.

A fundamental technical analysis indicator that calculates the unweighted arithmetic mean of an asset's closing prices over a specified number of past periods, filtering out short-term market noise to reveal the underlying trend.

An abrupt, intense, and disproportionately large upward or downward price movement occurring over an extremely brief time interval, typically driven by unexpected macroeconomic announcements, geopolitical shocks, or sudden order-book liquidity vacuums.

The Stochastic Oscillator is a momentum indicator developed by George Lane in the 1950s that compares a closing price to the price range over a specified lookback period, on a scale of 0 to 100. It identifies overbought conditions (above 80) and oversold conditions (below 20), and generates buy/sell signals through crossovers of its two lines: %K (the main line) and %D (the signal line).

Support is a price level or zone where buying pressure has historically been sufficient to prevent price from falling further. It represents an area where buyers consistently outnumber sellers, creating a floor that price struggles to break through. When support is broken convincingly, it often transforms into resistance — a key concept called 'role reversal' that forms the basis of many technical analysis entry strategies.

A bilateral technical chart pattern formed by two converging trendlines connecting sequential lower swing highs and higher swing lows, indicating a period of volatility compression and market indecision prior to a breakout.

Technical analysis is the study of historical price action and volume data to forecast future price movements. It operates on three core assumptions: market prices discount all available information, prices move in trends, and history tends to repeat itself through identifiable patterns. It is the dominant methodology among short- to medium-term forex traders.

A temporary, counter-trend price retracement within an ongoing primary market trend, triggered by technical factors such as overextended momentum, key chart resistance, or systematic profit-taking rather than a change in underlying macroeconomic fundamentals.

Technical indicators are mathematical formulas applied to historical price, trading volume, and open interest data to identify market trends, evaluate momentum, measure volatility, and forecast potential price turning points.

A trend in forex is the general direction in which a currency pair's price is moving over a specific period. Trends are classified as uptrend (higher highs and higher lows), downtrend (lower highs and lower lows), or sideways/ranging (no consistent directional bias). Identifying the trend is the foundation of technical analysis — the phrase 'the trend is your friend' encapsulates the statistical edge that trend-following strategies provide.

A trend line is a straight line drawn on a price chart connecting a series of swing highs or swing lows, representing the direction and angle of a trend. In an uptrend, a trend line connects rising swing lows and acts as dynamic support. In a downtrend, it connects falling swing highs and acts as dynamic resistance. Trend lines are one of the oldest and most widely used tools in technical analysis.

A triple top is a bearish reversal chart pattern formed when price tests the same resistance level three times and fails to break above it on all three attempts. It is an extended version of the double top, with the third failure confirming that sellers are firmly in control at that price level. The pattern completes — and generates a sell signal — when price breaks below the support level (neckline) connecting the two troughs between the three peaks.

A V-formation, or V-bottom (inverted as a V-top), is an abrupt technical chart reversal pattern characterized by an aggressive, steep price decline followed immediately by an equally rapid, high-momentum recovery without an intervening consolidation base.

A wedge is a chart pattern formed by two converging trend lines that slope in the same direction — both upward (rising wedge) or both downward (falling wedge). Unlike channels where the lines are parallel, wedge lines converge toward a point (apex). Rising wedges are typically bearish reversal patterns; falling wedges are typically bullish reversal patterns. They signal a compression of price movement that typically resolves with a breakout.

Weekly charts are multi-day technical analysis representations where each candlestick or bar aggregates five consecutive daily trading sessions, providing macro perspective by filtering out short-term market noise.

A Z-Score is a statistical metric that quantifies the number of standard deviations a given data point lies above or below the mean, widely applied in quantitative trading for mean-reversion modeling and corporate insolvency prediction via the Altman Z-score.

A technical analysis overlay that filters out market noise and minor price fluctuations below a specified threshold, connecting significant swing highs and swing lows to clarify structural trends, chart patterns, and wave counts.

A zone of support is a horizontal price range or band on a financial chart where concentrated buying interest historically halts downward price momentum, serving as a dynamic floor where demand overwhelms supply.
