The terms that come up in every scan, chart and trading book, defined in plain English. Where a term has its own scan or guide, the definition links to it.
- 8-K filing
- A report US companies file with the SEC to announce material events between quarterly reports — earnings releases, contracts, acquisitions, leadership changes. The episodic pivot scan reads 8-Ks to explain why a stock gapped. Read more
- Accumulation/Distribution rating
- A letter grade (A to E) for whether institutions appear to be buying or selling a stock, based on how price and volume behave on up days versus down days. Part of William O'Neil's CANSLIM ratings. Read more
- ADR (average daily range)
- The average percentage distance between a stock's daily high and low, usually over 20 days. Swing traders use it to filter for stocks that move enough to pay for a multi-day hold; the momentum scans require roughly 4% or more.
- Advance/decline ratio
- The number of stocks that closed up divided by the number that closed down on a given day. A breadth measure of how broadly a session was bought. Read more
- ATR (average true range)
- The average of each day's true range — the largest of high minus low, high minus prior close, and prior close minus low. Used to size stops and to measure how extended a stock is from its moving averages.
- Base
- A period of sideways price action after an advance, where a stock digests its gains before its next move. Bases are where breakout setups form. Read more
- Breakout
- A move above the top of a base or consolidation, ideally on expanding volume. The momentum breakout scan looks for tight bases after a large prior move. Read more
- CANSLIM
- William O'Neil's growth-stock method: Current earnings, Annual earnings, New highs or products, Supply and demand, Leader or laggard, Institutional sponsorship, and Market direction. Read more
- Capitulation
- A sharp, high-volume sell-off where remaining holders give up at once. Often marks a short-term low; the parabolic long scan looks for the first up day after one. Read more
- Catalyst
- The news behind a move: an earnings report, FDA decision, contract, or other event that changes how the market values a company. Read more
- Consolidation
- A stretch of narrowing price action where buyers and sellers are roughly balanced. Tight consolidations after a strong advance are the classic momentum setup.
- Dollar volume
- Shares traded multiplied by price. A better liquidity measure than share count alone, because it reflects how much money can move in and out of a position.
- EMA (exponential moving average)
- A moving average that weights recent prices more heavily than older ones, so it reacts faster than a simple average. The 10- and 20-day EMAs are common guides for momentum stocks.
- Episodic pivot
- A large gap on real news in a stock that had been going nowhere — the shape left when a catalyst genuinely re-rates a company. A setup popularised by Kristjan Kullamägi. Read more
- Float
- The number of shares available to trade publicly, excluding shares held by insiders and restricted holders. Smaller floats can move faster on the same buying.
- Gap
- An open well above or below the prior close, leaving a space on the chart. Gaps on heavy volume and real news matter more than gaps on nothing. Read more
- Market breadth
- Measures of how many stocks are participating in a move — the share above key moving averages, new highs versus new lows, advancers versus decliners. Read more
- Market regime
- An overall read of market conditions. SwingTradeScanner averages the percentage of stocks above their 50- and 200-day averages into a 0–100 score: Risk-On at 65+, Neutral from 45, Risk-Off below 45. Read more
- Moving-average stacking
- When shorter moving averages sit above longer ones — for example 50-day above 150-day above 200-day. It means every timeframe agrees the trend is up. Read more
- Net new highs
- The count of stocks making new 52-week highs minus the count making new 52-week lows. A healthy uptrend keeps producing new highs. Read more
- Parabolic move
- A near-vertical run where price rises (or falls) faster and faster over consecutive days. It rarely lasts; the parabolic short scan looks for exhaustion after one. Read more
- Pivot point
- The price level a setup must clear to trigger — usually the high of the final, tightest part of a base.
- Premarket
- Trading before the regular session opens at 9:30 ET, starting as early as 4:00 ET. Episodic pivots usually show up here first. Read more
- Relative strength (RS) rank
- A 1–99 percentile ranking of a stock's price performance against the rest of the market over recent months. An RS of 90 means the stock has outperformed 90% of stocks. Not the same as the RSI oscillator.
- RS line
- A stock's price divided by an index, plotted over time. A rising RS line means the stock is outperforming the market, even on days both fall.
- SEPA
- Specific Entry Point Analysis — Mark Minervini's method, which starts with his eight-point trend template and looks for a low-risk entry out of a tightening base. Read more
- Sector rotation
- The movement of money from one group of industries to another as conditions change. Leaders inside leading sectors have a tailwind a lone strong chart does not. Read more
- Stage 2
- The advancing phase in Stan Weinstein's four-stage model of a stock's cycle: price above rising moving averages, making higher highs. Where trend traders want to be long. Read more
- Trend template
- Mark Minervini's eight conditions a stock must meet to be in a confirmed uptrend, covering moving-average alignment, distance from the 52-week high and low, and relative strength. Read more
- VCP (volatility contraction pattern)
- A base in which each pullback is shallower than the last and volume dries up, showing sellers are running out of stock before a breakout. Read more
- Volume dry-up
- Volume falling well below average during a pullback or base. It suggests few holders are willing to sell at current prices.
