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.
Print
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.
