Volume
Technical analysisThe number of shares traded in a given period.
In plain terms
The only widely used input that is not derived from price, which makes it worth more than the four oscillators sitting under your chart. A breakout without a volume surge is a suspect breakout.
Read the full lesson →Volume profile
Technical analysisA study showing how much volume traded at each price level rather than in each time period.
In plain terms
Price moves fast where nobody is and stalls where everybody is. The lookback period determines every level, so anchor it to real structure and then leave it alone.
Read the full lesson →Volume smile
Trading & ordersThe shape traded volume makes across a session — heavy at the open, thin through the middle of the day, heavy again into the close.
In plain terms
Both ends hold most of the day's information and most of its danger. The first fifteen minutes are the most expensive; the close has the deepest liquidity.
Read the full lesson →Volume spread analysis
Technical analysisAlso called: VSA
Reading volume against the candle’s range to judge whether a move was easy or difficult.
In plain terms
Volume is effort, range is result. When they disagree, someone large is on the other side.
Read the full lesson →Volume weighting
Technical analysisWeighting each price by the volume traded there, so heavily traded prices count for more.
In plain terms
It stops a quiet day counting the same as a day when crores changed hands.
Read the full lesson →OBV
Technical analysisAlso called: On-Balance Volume
On-Balance Volume — a running total that adds the session's volume on up days and subtracts it on down days.
In plain terms
Rising while price goes sideways suggests quiet accumulation, which is the signature institutions leave when they cannot buy in one order.
Read the full lesson →High volume node
Technical analysisA price level on a volume profile at which an unusually large quantity has traded.
In plain terms
A great many participants transacted there, and every one of them has a reason to act if price returns.
Read the full lesson →Low volume node
Technical analysisA price level on a volume profile at which almost nothing has traded.
In plain terms
An air pocket. Nobody holds a position there to defend or to escape, so price travels through it quickly — useful for setting expectations about speed, not for choosing an entry.
Read the full lesson →Relative volume
Technical analysisToday’s volume divided by the average volume of the last 20 sessions.
In plain terms
The only honest way to judge volume — absolute share counts mean nothing across stocks.
Read the full lesson →Accumulation
Technical analysisSustained buying by informed participants, usually visible as heavy volume without much price progress.
In plain terms
Big money buying quietly, because buying loudly would move the price against them.
Read the full lesson →Additional Surveillance Measure
Regulation & taxAlso called: ASM
An exchange framework that applies tighter trading conditions to a security on the basis of its price and volume behaviour, in a short-term and a long-term form.
In plain terms
It reacts to how the share has traded, not to anything the company did. The bite is 100% upfront margin, which usually reaches you as a rejected order or a margin call before you have read the circular.
Read the full lesson →Bhavcopy
Market basicsThe end-of-day file published free by each exchange, carrying the session’s prices, volumes and related statistics for every security.
In plain terms
The primary source, before any app or aggregator has touched it. A two-minute download that settles most arguments about what actually happened.
Read the full lesson →Breakaway gap
Technical analysisA gap out of a consolidation on heavy volume, usually driven by genuine news.
In plain terms
The most significant gap type, and the one least likely to fill.
Read the full lesson →Capitulation
Risk & psychologyThe final phase of a decline, marked by heavy-volume selling and widespread exhaustion.
In plain terms
The mood is not caution — it is disgust, and people questioning whether equity works at all.
Read the full lesson →Chaikin Money Flow
Technical analysisAlso called: CMF
A volume indicator weighting each bar by where it closed inside its own high-low range.
In plain terms
Catches the big-volume day that looked green all session and closed on its low — a day the price chart records as a gain and this records as supply.
Read the full lesson →Climax
Technical analysisA wide, extreme-volume candle at the end of an extended move.
In plain terms
The last buyers arriving all at once, which leaves nobody left to buy.
Read the full lesson →Closing price
Trading & ordersOn Indian exchanges, the volume-weighted average price of the final thirty minutes of the session — not the last trade.
In plain terms
Designed so that one late trade cannot set the close, which makes manipulation substantially harder. It is also why a close beyond a level counts for more than a touch.
Read the full lesson →Confirmation
Technical analysisRequiring a second condition — volume, a close, a retest — before entering.
In plain terms
Waiting for a retest feels prudent and removes the strongest breakouts, which never retest.
Read the full lesson →Delivery percentage
Trading & ordersShare of the day’s traded volume that was actually delivered into demat accounts.
In plain terms
Separates real buying from intraday churn. An 8% move on 12% delivery means almost nobody wanted to own it.
Read the full lesson →Distribution
Technical analysisSustained selling into strength, typically at a top, with heavy volume and choppy sideways price.
In plain terms
The stock feels exciting while large holders hand their shares to newcomers.
Read the full lesson →Effort versus result
Technical analysisComparing the volume traded against the price movement it produced.
In plain terms
Huge volume and a tiny range means enormous effort achieved nothing — that is the signal.
Read the full lesson →Fixed cost
AccountingAlso called: Fixed vs variable cost
A cost that does not change with the volume produced or sold over the relevant range.
In plain terms
Rent, salaries and depreciation. They arrive whether forty customers come or four hundred.
Read the full lesson →Flag
Technical analysisA short, tight, low-volume drift against a sharp preceding move, which then resolves in the original direction.
In plain terms
The drying volume is what makes it a flag: profit-taking is being absorbed without difficulty. Past about three weeks it has become a distribution range instead.
Read the full lesson →Market share
Fundamental analysisA company’s revenue or volume as a proportion of its industry.
In plain terms
Growth means little without it. Growing 18% while the industry grows 22% is losing ground.
Read the full lesson →Naked chart
Technical analysisA price chart with every indicator stripped off, leaving candles and volume alone.
In plain terms
Every indicator is a lossy summary of price delivered late. This is reading the source rather than the summary.
Read the full lesson →Near-month contract
DerivativesAlso called: Front month, Current month contract
The listed futures contract with the closest expiry, which ordinarily carries most of the volume and open interest in the family.
In plain terms
The instrument your order actually joins. Levels, entries and stops belong on its chart; the spliced continuous chart is for shape and trend.
Read the full lesson →No demand
Technical analysisA move on unusually low volume, suggesting no real participation behind it.
In plain terms
The move had no fuel. Common just before a failed breakout.
Read the full lesson →Option chain
DerivativesThe strike-by-strike table of open interest, change in open interest, volume and implied volatility for an underlying's options, published live and free by the NSE.
In plain terms
The strike with the largest call open interest often acts as resistance and the largest put strike as support, because writers hedging those positions generate real buying and selling. One source of confluence, not a forecast.
Read the full lesson →Portfolio liquidation time
Market basicsThe headline figure of the fund liquidity stress test — the days needed to sell 25% and then 50% of the portfolio, computed pro-rata against trailing traded volumes.
In plain terms
Driven mostly by fund size measured against the volumes of what it owns, so the numbers cluster by size rather than by skill. The least liquid fifth of the portfolio is excluded before the figure is calculated, which is the single most important thing to know about it.
Read the full lesson →Price action
Technical analysisReading structure, levels, candle character and volume directly from the chart, without indicators.
In plain terms
Not a claim that indicators are useless — a claim about ordering. An indicator that tells you something the chart does not is almost always telling you about its own settings.
Read the full lesson →Pricing power
Fundamental analysisThe ability to raise prices without losing enough volume to matter.
In plain terms
About the buyer’s position at the moment of paying, not product quality. Salt has it; a thali does not.
Read the full lesson →Revenue bridge
Fundamental analysisAlso called: Growth bridge, Revenue walk
A reconciliation that walks from last year’s revenue to this year’s, attributing each part of the change to volume, price, mix or acquisition.
In plain terms
The pieces have to multiply back to the reported number, which is what stops you telling yourself a story. Half an hour with the volume tables and the business combinations note builds one.
Read the full lesson →Rising three methods
Technical analysisAlso called: Falling three methods
A continuation pattern: a long trend candle, then two to four small candles drifting back inside its range on lighter volume, then another long candle closing beyond the first one’s extreme.
In plain terms
The picture of a healthy pullback — shallow, unhurried and unsupported by volume, meaning nobody is willing to sell in size. The falling three methods is the same structure inside a downtrend.
Read the full lesson →Roll method
DerivativesAlso called: Roll rule, Roll date
The rule a data vendor uses to decide when a continuous series stops following one futures contract and starts following the next — on expiry, a fixed number of days before it, or when volume and open interest migrate.
In plain terms
A second undisclosed choice on top of the adjustment method. It changes which sessions appear on your chart at all, so two platforms can disagree about the candles as well as the levels.
Read the full lesson →Sign of strength
Technical analysisIn Wyckoff analysis, the break above the top of an accumulation range on expanding volume and wide-range candles.
In plain terms
Accumulation is complete and markup begins. It is the first point in the sequence most people can act on with reasonable odds.
Read the full lesson →Technical analysis
Technical analysisThe study of price and volume history to judge probable future price behaviour.
In plain terms
Reading the crowd through the record it leaves on a chart.
Read the full lesson →VWAP
Technical analysisVolume Weighted Average Price — the session’s average price weighted by volume traded at each level.
In plain terms
What the average participant paid today. Institutions benchmark their fills against it.
Wyckoff
Technical analysisAlso called: Wyckoff method
A framework from the early 1900s for reading accumulation and distribution from price and volume alone.
In plain terms
It addresses a constraint that has not changed: a large buyer cannot buy quickly without destroying their own price. Take volume away and it becomes drawing boxes on a chart.
Read the full lesson →Absorption
Technical analysisHeavy selling met by a buyer large enough to prevent the price falling.
In plain terms
High volume, narrow range, close near the high after a decline. The candle looks boring, which is why it is missed.
Read the full lesson →Breakout
Technical analysisA decisive close beyond an established support or resistance level.
In plain terms
Only credible with a volume surge. Without one it is usually a trap.
Read the full lesson →Breakout trading
Technical analysisBuying a decisive close beyond a consolidation range, on the expectation that compression resolves into a directional move.
In plain terms
The volume filter is the strategy. A breakout on below-average volume is a thin order book making a big-looking move that gets handed straight back.
Read the full lesson →BSE
Market basicsBombay Stock Exchange, founded 1875 — Asia’s oldest exchange, home of the SENSEX.
In plain terms
The older exchange. More listed companies, much less trading volume.
Read the full lesson →Claim settlement ratio
Regulation & taxThe proportion of death claims an insurer settled over a year, counted by number of claims.
In plain terms
A count, not a measure of value or difficulty, and inflated at some insurers by large volumes of small group claims. More useful read alongside the average time taken to settle.
Read the full lesson →Consolidated tape
Trading & ordersA single combined feed of every trade in a security across all venues — a feature of United States market structure with no Indian equivalent.
In plain terms
India has no combined national print. Each exchange broadcasts its own trades, so the volume figure you read belongs to one venue rather than to the market.
Read the full lesson →Continuation pattern
Technical analysisAlso called: Continuation patterns
A candle or price formation describing a trend pausing rather than reversing, before resuming in the original direction.
In plain terms
The test is territorial, not visual: if the pause stays inside the ground the trend already won and volume thins while it happens, it is a rest. If it takes that ground back on rising volume, the name of the shape stops mattering.
Read the full lesson →Discounting
Technical analysisThe first assumption of technical analysis — that every known fact, forecast and emotion is already expressed in the price.
In plain terms
You do not need to know why a large fund is accumulating. The accumulation shows up as rising price on rising volume whether or not the reason is public.
Read the full lesson →Evening session
DerivativesAlso called: Extended commodity session
The extended trading session Indian commodity derivatives run after the equity market closes, so that domestic contracts can track international markets while those are open.
In plain terms
It usually carries most of the day’s volume, which means a daily commodity candle averages two very different markets — a thin Indian afternoon and an active overseas evening.
Read the full lesson →Exhaustion gap
Technical analysisA gap occurring late in an extended move, marking the arrival of the final buyers or sellers rather than a continuation.
In plain terms
Almost always fills, and quickly. The tell is record volume followed by wide-ranging sessions that go nowhere — heavy activity with no progress.
Read the full lesson →Expiry
DerivativesThe day a derivatives contract ceases to exist.
In plain terms
Much of the volume is position unwinding rather than a view, so price action means little.
Read the full lesson →Head and shoulders
Technical analysisA reversal pattern of three peaks with the middle highest, completed on a break of the neckline.
In plain terms
Three rallies, each recruiting fewer buyers. Volume must fade into the right shoulder.
Read the full lesson →Indicator redundancy
Technical analysisThe condition in which several indicators appear to confirm one another while being different arrangements of the same underlying price data.
In plain terms
RSI, Stochastic, Williams %R, CCI and the MACD histogram all agreeing is one opinion reported five times. New information has to come from a different input — volume, breadth, relative strength.
Read the full lesson →Industry consolidation
Fundamental analysisA fall in the number of participants in an industry as capacity is retired, acquired or resolved through insolvency, leaving the survivors facing less competition.
In plain terms
The tell that it is actually working is that realisations stop falling before volumes recover — price discipline needs only a decision, demand needs a cycle.
Read the full lesson →Installed capacity
Fundamental analysisAlso called: Rated capacity, Nameplate capacity
The maximum output a company’s plants are rated to produce over a period, disclosed in units rather than rupees.
In plain terms
The ceiling on volume growth without fresh capital expenditure. Set beside actual production it gives capacity utilisation, and beside industry-wide additions it tells you what supply is coming.
Read the full lesson →Liquidity sweep
Technical analysisA move through an obvious level that triggers resting orders and then reverses.
In plain terms
Break on volume, no close beyond, quick reclaim. A genuine breakdown holds; consuming a pool of stops does not.
Read the full lesson →Muhurat trading
Market basicsA short symbolic trading session held on Diwali.
In plain terms
A tradition rather than an opportunity — thin volume and wide spreads.
Read the full lesson →Price cap
Fundamental analysisA statutory or regulatory limit on the maximum price at which a good or service may be sold.
In plain terms
Where one applies, competitive strength stops being a pricing question — the brand cannot buy a rupee above the notified figure. Volume, mix and cost position are the only levers management still holds.
Read the full lesson →Pullback entry
Technical analysisBuying a temporary decline within an established uptrend, at a moving average or Fibonacci retracement, on a bullish reversal candle.
In plain terms
The best risk-reward of the common templates, because the stop sits just under a nearby low. Skip it when the pullback arrives on heavier volume than the advance — that is distribution.
Read the full lesson →Range expansion
Technical analysisA sharp increase in daily range after a period of compression.
In plain terms
The resolution of a squeeze. Volume on the expansion is what separates a real one from a trap.
Read the full lesson →Sales mix
Fundamental analysisAlso called: Product mix, Mix effect, Revenue mix
The composition of what was sold — across products, variants, geographies or channels — which changes revenue and margin without any change in total units.
In plain terms
Watch the share of revenue against the share of units. When those two move apart, mix is doing the work rather than volume or price.
Read the full lesson →Take rate
Fundamental analysisA platform's net revenue as a share of the gross value of the transactions it processes.
In plain terms
Rising means the platform is being paid more for what it does. Falling usually means volume is being bought with discounts, which appears in the accounts as growth.
