Stock Market Terms
A practical glossary for active traders, organized from levels and order flow to setups, risk, float dynamics, catalysts, and scanning.
1. Levels & Risk
- VWAP
- Volume-weighted average price for the session — the default fair-value line on an intraday chart. Holding above it means longs are in control; failing below means shorts are. On VWAP = testing it. Off VWAP = bouncing away from it.
- Guide
- The price used as risk. Usually VWAP, HOD, LOD, or a whole/half dollar.
- HOD / LOD
- High of day / low of day. The most common stop and the most common trigger. “Risking to HOD.”
- Key area / key level
- The support or resistance that decides the next move.
- Magnet
- A psychological round number the stock gets drawn to — $5, $10, $100.
- Over / under
- A decision level. Trade the reaction above or below it, not a prediction of which way it goes.
- R/G (red / green)
- Crossing from down-on-day to up-on-day, or the reverse. A sentiment flip, not just a price.
- Reject
- A failed break of HOD, VWAP, or resistance.
- Reclaim
- Lost a level, then took it back. The classic “shorts trapped / longs re-empowered” tell.
- Close / closer
- Price approaching a level that matters.
- Risking to
- Where the stop sits, mental or hard. “Short, risking to HOD.”
- Max stop
- A hard account-level stop — especially important off opening wicks.
- Halt levels / circuit bands
- The prices that trigger a volatility pause. Track them in advance so you are not stuck in a position you cannot exit.
- Target / target range
- The planned exit zone, set before entry.
- Trade plan
- Levels written down before the open, not improvised mid-move.
- On radar / off radar / revisit later
- Watchlist status: setup forming, setup dead, or come back to it.
- Support / resistance
- Prices where buyers have previously stepped in (support) or sellers have previously capped price (resistance).
- AVWAP (anchored VWAP)
- VWAP measured from a chosen starting point — a gap, halt, or news print — rather than from the open. Shows the average price paid since that event.
- Moving average
- A rolling average of price over N periods, such as 9, 20, or 200. Used as dynamic support/resistance and a trend filter.
- Higher high / higher low
- Successive peaks and troughs both rising. The textbook definition of an uptrend.
- Lower high / lower low
- Successive peaks and troughs both falling. A downtrend — and the structure behind “heavy.”
- Trendline
- A line connecting successive lows in an uptrend or highs in a downtrend. A moving guide rather than a fixed one.
- Prior day high / low
- Yesterday’s extremes. Common overnight reference levels and gap targets.
2. Tape & Order Flow
- Bid / bidder
- A large resting buy order sitting on Level 2.
- Swipe
- An aggressive lift of the offers — buyers hitting asks.
- Swipe test
- Does the reclaim get stuffed by real sellers, or hold because it is only shorts covering? The answer tells you whether the move is real.
- Slam / stuff
- An aggressive hit of the bids — sellers dumping into whatever is there.
- Stuff vs. soak
- An exhaustion dump that stays heavy (stuffed) versus one that gets bought immediately (soaked). Same candle, opposite meaning.
- Push / pull
- A short burst up or down that may precede the real move.
- Pops
- Quick spikes inside a downtrend. The place to sell weakness — as opposed to chasing rips.
- Perk / gear / curl
- Price starting to lift out of a channel. The earliest sign of a momentum change.
- Ramp
- A rising move that is not parabolic yet.
- Grind
- A slow, stubborn drift higher that refuses to break.
- Fade / steady fade / non-stop fade
- Persistent selling with few bounces, often all session. Do not catch the knife.
- Unwind / unwinding
- A clean downtrend with almost no bounces at all.
- Heavy
- Cannot get lift: lower highs, failed follow-through, no bid. A short candidate.
- Moving on air / floating on air
- Big range on thin volume. Fragile — it can reverse as fast as it moved.
- Never breach VWAP
- A runner that absorbs every short while holding VWAP the whole way up. Not one to fade.
- Circuit-to-circuit
- Repeated halt bands, one after another — often while never breaching VWAP and absorbing shorts the entire time.
- Circuits / halt
- A volatility halt. You cannot exit while it is on. This is the risk that can punish oversized positions.
- Thin / low float
- Small share supply. Small orders move it a lot.
- Volume (as an alert)
- Relative volume is picking up. The name is in play.
- Liquidity vs. volume
- Volume can look perfectly fine and still not let you out. They are not the same thing.
- No fill
- Not enough actual bids or offers to exit at any reasonable price.
- Indication
- The pre-open indicated price. A stress check on the open, not an entry.
- Low liquidity environment
- Few competing buyers and sellers, so small orders move price more than they should.
- Ask / offer
- The lowest price a seller is currently willing to accept. Buying at the ask means paying up.
- Spread
- The gap between bid and ask. Wide spreads mean thin liquidity and expensive round trips.
- A completed trade on the tape. “Big print” means unusual size crossing.
- Tape
- The live stream of executed trades. Reading the tape means reading speed, size, and who is being aggressive.
- Level 2
- The order book: resting bids and offers stacked by price and size across market makers and ECNs.
- Time and sales
- The printed record of every execution — price, size, and timestamp. The companion to Level 2.
- ADV (average daily volume)
- How much a name normally trades. The denominator that makes RVOL meaningful.
- RVOL (relative volume)
- Today’s volume as a multiple of its average. A key “is this in play” filter.
- LULD
- Limit up / limit down — the price bands that trigger a volatility halt when price moves too far too fast.
- Circuit breaker
- The mechanism that pauses trading when an LULD band is breached. What “circuits” refers to.
- News halt
- A halt called for pending news rather than volatility. It reopens at a fresh price with no way to have exited.
- Accumulation
- Buying absorbed quietly over time without pushing price up. The mirror of distribution.
- Supply / demand
- Shares available for sale versus buying interest. Every squeeze argument is ultimately a supply argument.
- Bid support
- Persistent buyers holding a price up. When it disappears, price slides fast.
- Offer resistance
- A persistent seller capping a price. Absorbing it is what makes a breakout real.
3. Setups & Patterns
- ABCDing / ABCD
- The classic momentum pattern: run, pullback and base, then the next leg.
- Bases / basing
- Tight consolidation after a move. The base is the entry — not the first spike.
- Failed follow through
- A breakout attempt that dies. Often the short trigger itself.
- Next leg up / down
- The continuation that comes after a base holds.
- Fresh highs / fresh lows
- New extremes after consolidation. Puts the name back on radar.
- Holding trend
- Pullbacks or spikes happen, but the day’s direction is intact.
- Trending
- A one-direction day with low chop.
- Squeezing
- Upside driven by shorts covering, not by new buyers.
- Gapper
- Holding overnight after a strong close, betting on morning follow-through.
- Washout / wash
- A fast flush that hits stops and clears weak holders. The buy is off the wash, not into it.
- Flush-out candle
- The wick that knocks out everyone who used the low as their risk level.
- Hammer candle
- The reversal bar that prints after a flush.
- V-shape reversal
- A violent reclaim after a flush. Repeated V-shapes in the same name are often distribution by price.
- Right side of the V
- Trade the reclaim after the flush — not the first dump.
- Double top
- Two failed tests of the same high, often premarket or opening resistance.
- Walk-down trap
- A premarket or early fade that looks perfectly shortable, then snaps up.
- Re-trap
- A second trap at a known level, after the first one already burned one side.
- Low-volume trap
- Looks shortable because volume is light — but price never gives shorts the VWAP or structure break they need.
- Dip and rip
- Fade, trap the shorts, then squeeze. The core squeeze structure.
- Daily slide after daily squeeze
- The same name squeezes and then fades, every single session.
- PR reject
- A news spike that fails. Fade the failed catalyst.
- Shuffle
- The same pattern repeating across a group of names — one leader’s structure showing up in every sympathy.
- Coiled
- A compressed range right before expansion.
- Rip / ripper / rip stick
- A sharp upside burst, in the stock or in the options.
- Breakout / breakdown
- Price clearing resistance (breakout) or losing support (breakdown) with volume behind it.
- Pullback
- A countertrend dip inside an uptrend. Generally a better entry than the highs.
- Consolidation
- A pause where price moves sideways and range contracts. Same idea as a base.
- Range
- A defined band price keeps oscillating between. Fade the edges until it breaks.
- Channel
- A sloped range — a trend with parallel upper and lower bounds.
- Trend
- A persistent direction: higher highs and higher lows, or the reverse.
- Reversal
- A change in direction that holds. Not to be confused with a bounce inside a trend.
- Continuation
- The trend resuming after a pause. The other half of every ABCD.
- Gap
- An overnight price jump — today’s open away from yesterday’s close. The starting condition for many small-cap plays.
- Gap fill
- Price trading back to yesterday’s close, closing the gap. A common magnet and target.
- Gap and go
- A gap that holds and extends off the open. The bullish resolution.
- Gap and crap
- A gap that fails immediately and sells off. The bearish resolution — and the reason to wait past 9:30.
- Chop / choppy
- Directionless back-and-forth. The condition that stops out both sides.
- Trend day
- A day that goes one direction and does not look back. Hold, do not scalp.
- Range day
- A day that oscillates between two levels. Scalp the edges, do not hold for a trend.
- Runner
- A name that is genuinely running — big percentage move on big relative volume.
- Multi-day runner
- A runner extending over consecutive sessions. Where float rotation and backside setups live.
- Climax / climax top
- The final blow-off surge on peak volume, right before the move fails.
- Exhaustion
- The point where the aggressive side runs out of participants. Precedes the reversal.
- Dead-cat bounce
- A weak bounce inside an ongoing downtrend that fails and makes new lows.
- Bull trap
- A breakout that immediately fails, trapping the longs who chased it.
- Bear trap
- A breakdown that immediately reverses, trapping the shorts who pressed it.
- Fakeout
- Any break of a level that does not hold. The generic form of both traps.
- Wick
- The thin part of a candle beyond the body — where price went but could not stay. Where stops get taken.
- Shooting star
- A long upper wick with a small body. Rejection at the highs.
- Doji
- Open and close nearly equal. Indecision; only meaningful at an extreme.
- Engulfing
- A candle whose body fully covers the prior one. A momentum shift in a single bar.
- Double bottom
- Two failed tests of the same low. The inverse of the double top.
4. Position & Risk
- Starter / starting
- The first piece. Confirmation comes before real size does.
- Adding
- Adding to a position that is already working.
- Scale / scaling in
- Building in pieces so you are never all-in on a guess.
- Core position
- The day or swing thesis. Scalped around rather than traded whole.
- Leaving room
- Sizing small enough that a normal wiggle does not stop you out.
- Locking in / pay along the way
- Taking partials so a winner never turns into a loser.
- All done / done w/
- Flat. Out of the position entirely.
- Chase / chasing
- Buying or selling after the move already happened. A mistake unless size is tiny.
- Buying on dips
- Adding on pullbacks in an uptrend instead of lifting the highs.
- Leaning
- Slowly building a short into strength and pops, rather than all at once.
- Higher better
- Let it run so the short is better later — more extension, more trapped longs. The opposite of chasing a short too early.
- Put risk on
- Actually take the trade, after having waited for it.
- Size
- Share count or dollars at risk. Size does not always make you more.
- Oversize / oversized
- Too big for the halt and liquidity risk actually present in the name.
- Cover
- Buying back a short.
- Missed cover / couldn’t fill
- You wanted out and there was no liquidity. A known risk accepted before entry — not a surprise.
- Long / short / flat
- Owning shares (long), having sold borrowed shares (short), or holding nothing (flat).
- Scalp
- A trade held seconds to minutes for a small, defined move.
- Day trade
- A position opened and closed within the same session. No overnight risk.
- Swing
- A position held across multiple sessions on a multi-day thesis.
- Average in
- Adding at worse prices to improve the blended cost basis. Fine when planned, fatal when it is just hope.
- Trim
- Selling part of a position while keeping the rest. The mechanic behind “pay along the way.”
- Stop / stop out
- The exit that caps a loss — and the act of being taken out at it.
- Hard stop vs. mental stop
- A resting order in the market versus a level you have committed to honor manually. Hard stops can be run; mental stops can be ignored.
- Risk / reward
- Expected gain measured against the loss you accept to get it. The number that makes a low win-rate strategy work.
- R-multiple
- Profit or loss expressed in units of your initial risk. A +3R winner made three times what you risked.
- Drawdown
- The decline from a peak in the account. Measured in dollars and in confidence.
- Blow up / blown account
- A loss large enough to end the account. Almost always oversize plus a halt.
- Margin
- Borrowed buying power. It magnifies both sides, and it is what turns a bad trade into a blown account.
5. Squeeze, Float & Borrow
- Float
- The shares actually available to trade.
- Float rotation
- Volume trades many times the listed float. Original holders have had every chance to exit, new buyers hold a much higher cost basis, and shorts who keep adding get run over. Once the float rotates, the original gap no longer matters.
- Higher the thinner
- After a big run and a rotated float, each new high has less real supply behind it. Dangerous to fight.
- Front side
- The early, still-extending part of the squeeze. Not a place for size.
- Back side / backside
- After the squeeze clears and longs become the trapped side. Where the short setup actually lives.
- Parabolic
- A vertical, late-stage run. A backside candidate after it fails — not during.
- Add add add
- Shorts stacking size into strength out of disbelief. A warning sign, not a plan.
- Blow out the shorts
- Forcing covers. Price can then run because the flow is covering, not selling.
- Stuck / shorts stuck / longs stuck
- One side is committed at a bad price. That is the fuel.
- SSR
- Short sale restriction — the uptick rule that kicks in after a big down day. Changes how shorts are allowed to hit bids.
- SSR trap
- A walk-down that looks shortable, then rips because shorts are restricted and get trapped.
- Locate / borrow
- The permission and inventory you need in order to short.
- Hard to borrow / HTB
- Scarce borrow. Squeeze fuel.
- Borrow now, pay later
- Shorts get an easy late-day fill, then pay for it after hours when supply thins out.
- T+1 / FTD / buy-in
- Settlement and failure-to-deliver pressure that can force covers days after the first spike.
- Lock shorts in day one
- Trap them on day one, then let the squeeze come later — on buy-ins, or on price alone.
- Let shorts “win” into the close
- The classic late-day fade that makes shorts look right — then after-hours or premarket punishes them.
- Rigger / rigger supply
- Thin, tightly-held small-cap squeeze vehicles — and the thin after-hours or premarket offer they run shorts into.
- Shell game / rigged casino
- Labels for what front-siding those names actually amounts to.
- Outlier / black swan
- A range that should not be possible given the float — unless volume rotated it.
- Short interest
- The number of shares currently sold short. High short interest is fuel, not a guarantee.
- Days to cover
- Short interest divided by average daily volume. How long shorts would need to exit at a normal pace.
- Utilization
- The percentage of available borrow already lent out. Near 100% means the next short pays up or cannot get in.
- Borrow fee / locate fee
- What you pay to short a hard-to-borrow name. A rising fee is a real-time squeeze-pressure gauge.
- Restricted float
- Shares that exist but cannot trade — insider lockups or unregistered stock. Shrinks the real tradable supply.
- Outstanding shares
- Every share issued, including restricted ones. Always larger than the float.
- Reg SHO
- The SEC rule set governing short sales, locates, and failures to deliver. The source of SSR and the threshold list.
- Settlement
- When a trade legally completes and shares change hands — now T+1. The clock behind buy-ins.
- Short squeeze
- Price rising because shorts are forced to buy back, which pushes it higher and forces more covering.
- Gamma squeeze
- Option dealers buying stock to hedge calls they have sold, which pushes price up and forces more hedging. Stacks on top of a short squeeze.
- Delta
- How much an option’s price moves per $1 in the stock. Also how many shares a dealer must hold to stay hedged.
- Gamma
- How fast delta changes as the stock moves. High gamma is why dealer hedging accelerates into a run.
- Naked short
- Shorting without securing a borrow. Often used loosely as shorthand for supply that should not exist.
6. Crowd & Psychology
- Risk on / risk off
- Is the tape rewarding aggression or punishing it? The regime question — and it matters more than any individual setup.
- Scale tips
- Which crowd is getting stuck. When the scale tips, the next move is violent.
- Crowded
- Too many people in the same idea. Crowded short means squeeze risk; crowded long means air-pocket risk.
- Trap
- One side is committed at a bad price. The squeeze or dump that follows is the payoff.
- Chase it all
- Late, sloppy risk-on across the board. A warning, not an invitation.
- Distribution by price
- Selling into strength and V-reversals that dump longs at the highs.
- Distribution by time
- After the spike, the move just dies as volume fades. No crash required.
- FUD
- Fear, uncertainty, doubt. A coordinated wave of it sometimes turns out to be cover for accumulation.
- In play
- Volume plus range. Worth watching today.
- A+ setup
- The highest-conviction, pre-planned idea from the scan. Usually the only kind worth sizing before the open.
- Theme
- The tape’s current recipe — after-hours squeezes following late-day short wins, repeat-name V’s, or whatever is working that week.
- Sympathy / sympathies
- Related names that move with the leader. Often a cleaner trade than the leader itself.
- Basket / names
- A group of related tickers — memory, shipping, meme, and so on.
- Relative strength / weakness
- One name leading or lagging the rest of its basket.
- Stay in your lane
- Do not copy someone else’s size or someone else’s style.
- FOMO
- Chasing because other people are printing.
- Conviction vs. risk
- High conviction with poor risk still kills you. The two are separate questions.
- Gamified tape
- The modern small-cap tape — structured, more than ever, to trap whichever side is crowded.
- Career-risk event
- The trade that can end an account rather than just a day: a halt you cannot exit, a gap against oversize, or a squeeze with no borrow left.
- Graduate / bigger size
- Leaving small-cap casino size behind for mid- and large-cap, where liquidity actually lets you out.
- You only need to get rich once
- Keeping it beats chasing the next small cap.
- The house will win
- Stay at the small-cap table long enough and it takes the money back.
- Pump
- Coordinated or promotional buying that inflates price on no real change in the business.
- Dump
- The exit that follows a pump, into the buyers it attracted.
- Pump and dump
- The full cycle. The structural reason non-organic volume is borrowed, not owned.
- Bagholder
- Whoever is left holding at the top after the crowd leaves.
- Paper hands / diamond hands
- Selling quickly versus refusing to sell. Meme-tape framing — descriptive, not advice.
- BTFD
- “Buy the dip.” Crowd shorthand for the reflex that works right up until the trend actually breaks.
7. Session & Timing
- Premarket (PM)
- Pre-9:30 action, where many traps and ideas start. Rarely a place for size unless the setup is A+.
- Open / opening wicks
- The first minutes. Lethal if you are oversized.
- 9:30–9:45 / 10:00
- The reactive window. Do not commit — re-evaluate against VWAP once it settles.
- Midday / 11:30 check-in
- If names are not doing what you expected by now, get smaller or get out.
- Power hour / EOD / into the close
- Last-hour volatility: ramps, dumps, and late-day positioning games.
- After hours (AH)
- The post-4:00 tape. Thinner, easier to squeeze or slide. A favorite squeeze window.
- Hold overnight / swing idea
- A multi-session thesis, not a scalp.
- Opening print
- The first official trade of the regular session. The reference point everything early gets measured against.
- Opening drive
- A strong directional push straight off the open that does not retrace. Rare and hard to fade.
- Morning panic
- A sharp flush in the first hour that clears weak holders. Often where the day’s low prints.
- Afternoon slump
- The midday-to-early-afternoon liquidity lull. Ranges tighten and fills get worse.
- Overnight inventory
- Positions carried through the after-hours and premarket session. Determines who is already trapped at the open.
- Imbalance
- Excess buy or sell interest published ahead of the close. Drives the last-minute move into 4:00.
- MOC / LOC
- Market-on-close and limit-on-close orders. They execute at the closing auction and create the imbalance.
- Settle / the close
- The official closing price. What R/G, gaps, and overnight P&L are all measured against.
- Intraday vs. daily chart
- Timeframes. The daily chart sets the thesis; the intraday chart sets the entry and risk.
8. Catalysts & Corporate
- PR / news / catalyst
- The press release or headline driving the gap.
- Puts / calls
- Options. “Fade puts,” “parabolic index calls.”
- FOMC
- Fed day. The first parabolic move after the announcement is often the one that fails.
- Forward split
- A share split that changes the chart math and resets visual reference points.
- IPO / new issue
- No history and real halt risk. No size unless it was planned.
- Meme / meme tape
- Crowd-driven tape where positioning outweighs fundamentals. It can stay irrational longer than you can stay solvent.
- Dilution / offering
- New shares hitting the market — the supply that ends many small-cap runs.
- Offering
- A company selling new shares. Direct supply hitting the market — a common way a small-cap run ends.
- ATM offering
- An at-the-market program that lets a company sell shares continuously into strength. Invisible, constant supply.
- S-1 / S-3
- Registration filings that let a company sell new stock. An S-3 shelf can be drawn on with little warning.
- Shelf
- Pre-registered shares a company can issue whenever it wants. A loaded gun sitting over the chart.
- Reverse split
- Consolidating shares to lift the price — usually to keep a listing. Shrinks the float, which is why post-reverse-split names can squeeze.
- Ticker change
- A new symbol, often after a merger or reverse split. Breaks chart history and scanner memory.
- Promotion
- Paid campaigns pushing a stock. Non-organic demand with a known expiry.
9. Market Context
- Small cap / mid cap / large cap
- Risk buckets. Size rules, liquidity, and halt risk differ in each.
- SPY / QQQ / IWM
- The S&P 500, Nasdaq 100, and small-cap index ETFs. The market backdrop that sets whether risk is on.
- Sector
- The industry group a name belongs to. Sector strength is what turns one runner into a basket.
- Correlation
- How tightly two names move together. High correlation means your positions are one bet, not several.
- Beta
- How much a name moves relative to the broad market. High beta amplifies both directions.
- Breadth
- How many names are participating, not just how the index looks. Narrow breadth is a fragile tape.
- Macro
- Rates, inflation, and policy — the conditions that set overall risk appetite.
- CPI
- The monthly inflation print. A scheduled volatility event that resets risk-on/risk-off.
- Earnings
- Quarterly results. A scheduled catalyst with a known date and an unknown reaction.
- Guidance / beat / miss
- Forward outlook, and results above or below expectations. Guidance usually moves the stock more than the beat does.
- Rumor
- Unconfirmed news moving price. Trade the reaction, not the claim.
- Market cap
- Share price times shares outstanding. The number that makes an outlier move look absurd on paper.
10. Scanning & Flow Sources
- Organic vs. non-organic
- Real buyers versus alert-service buyers.
- Chat pump / newsletter
- Third-party alert flow. Non-organic buyers sell together, so the same shares come right back for sale.
- Scanner
- Software surfacing names by volume, percentage move, or float. Where the day’s candidates come from.
- Alert
- An automated or posted notification that a name hit a condition. A prompt to look, never a reason to buy.
- Gainer / most active
- Standard scan lists — biggest percentage movers and highest-volume names.
- Watchlist
- The curated shortlist you actually trade from, built the night before.
