In a liquid two-sided market, every traded price is the result of an ongoing auction. Price moves up to find sellers. Price moves down to find buyers. When both sides agree at a level, trade happens and the auction pauses there. When one side is absent, price keeps moving until it finds them. That one mechanism, described identically by Dalton in 1993 and Wyckoff in 1923, is what this entire concept is built on. Below is where the mechanism comes from across ten source traditions, followed by a real drilled scenario showing how the framework can be applied to an actual Nifty move.
The mandi, before the theory
A vendor at the vegetable mandi has tomatoes. He starts at ₹40 a kilo. No buyers. He drops to ₹35. Still nothing. He drops to ₹30, two buyers step up, and he stays there, he's found where demand actually is. A second vendor arrives with fewer tomatoes. Now two buyers want them, and they start bidding, ₹32, ₹35, ₹38, until the vendor holds firm and the buyers accept. That is exactly what Nifty does, every second the market is open. Price drops to find buyers. Price rises to find sellers. When both sides agree, trade happens. When one side is absent, price keeps moving until it finds them.
Price moves toward levels where sufficient buyers and sellers are willing to transact. When trade is comfortably facilitated, the auction can spend time there; when it is not, price searches elsewhere.
Dalton's definition of the auction
This is the foundational idea the rest of the concept sits on. Not a formula, not a calculation, an auction between human beings, buyers and sellers, every moment the market is open. Price moves up to find sellers, down to find buyers. When it finds a level where both sides trade in volume, it stays there. When it can't find enough participants, it keeps moving.
What price actually is, and why it moves before the news
Elder states the same fact more precisely: "Each price is the momentary consensus of value of all market participants. It shows their latest vote on the value of a trading vehicle." Every Nifty price is a vote, cast by every buyer and seller simultaneously, the price is just the tally. Livermore discovered why this matters at fourteen years old, posting stock prices on a board. Lefevre records it directly: "Hollow Tube went down three points the other day while the rest of the market rallied sharply. That was the fact. On the following Monday you saw that the directors passed the dividend. That was the reason." The people who knew acted first. Their selling moved price. The news came later. Price can move before public news because participants may act on information, expectations, positioning, or order flow before the wider market understands the reason. News may explain a move after the fact, but the immediate mechanical cause is still the orders that actually transact and move the auction.
The bid, the ask, and the one rule nobody teaches retail
Two prices exist at all times, not one. The bid is the highest price a buyer will pay right now, a waiting, passive limit order. The ask is the lowest price a seller will accept right now, also passive. The gap between them is the spread. Villahermosa is explicit about the part most retail traders never get taught: "Passive buy orders cause the downward movement to slow down, but by themselves cannot drive the price up. The only orders that have the ability to move the price upwards are buy-to-market orders." Passive orders can absorb or slow a move; aggressive orders cross the spread and consume resting liquidity, which is what allows price to advance through available levels. A large move accompanied by meaningful activity is therefore more informative than a price move viewed in isolation.
How price actually moves: the three-step protocol
IS
CONSUMED
A useful way to understand many sustained price moves, across timeframes, is as a three-step sequence. Step one, exhaustion of the dominant side: the aggressive force behind the current move runs out of conviction or capital, the push subsides. Step two, passive positioning by the opposite side: the other side begins quietly placing limit orders at current levels, supply or demand appears without fanfare. Step three, initiative by the opposite side: the opposite side turns aggressive, hits market orders, and forces price in the new direction. Wyckoff observed this exact pattern in 1923. Dalton confirmed it in 1993. Villahermosa applied it in 2020 with order-flow data. Same mechanism, every era, because it isn't a theory about markets, it's a description of how any two-sided negotiation actually behaves.
Who is actually in the market
Short-term participants trade frequently and can provide liquidity around the current market. Other-timeframe participants operate on longer horizons and may become more active when price moves sufficiently away from the value they perceive. Alongside these two broad horizons sit hedgers, who offset business risk; institutional and proprietary speculators, who can transact in significant size; algorithmic and high-frequency participants, who may provide liquidity or exploit short-lived inefficiencies; and retail traders, whose collective behaviour can matter even though each participant is usually smaller individually. The important point is that the chart does not reveal a participant's identity with certainty. Price, volume and open interest can provide evidence for an interpretation, but they do not by themselves prove who placed the orders.
Price versus value, the distinction most traders skip
Price is where the last transaction occurred, objective, a fact. Value is where participants believe the asset should trade, subjective, different for every participant and every timeframe. When price equals value, both sides are comfortable, volume is high, movement is small. When price sits above value, sellers turn aggressive and push it back. When price sits below value, buyers turn aggressive and push it back. This is the actual mechanism behind why support and resistance exist, participants remember where value was, and respond the same way when price returns to it. It isn't a magic line on the chart, it's a memory of where the auction was previously comfortable.
The three states, and what the professional does in each
For practical analysis, Nifty can be framed in three broad auction states: State 1, Balance: neither side has conviction, the auction is searching for information. In a balanced auction, forcing a directional trade without evidence can offer poor expectancy; patience may be the better decision. State 2, Buyer imbalance: buyers are more aggressive, price trends up, the auction is searching for sellers above. The professional looks for pullbacks to enter long. State 3, Seller imbalance: sellers are more aggressive, price trends down, the auction is searching for buyers below. The professional looks for rallies to enter short. Grimes adds the warning that matters most here: "There can be sudden, sharp moves within trading ranges, but they are often more or less unpredictable." Inside balance, there is no edge. The only question that matters before any trade is which of these three states Nifty is actually in.
Price, time, and volume, together
Price discovers where the auction is currently searching, it's the search mechanism itself. Time confirms acceptance or rejection, Villahermosa's exact words: "The price will spend very little time in those zones that are advantageous to one of the two sides. A zone of efficiency or equilibrium will be characterized by a higher consumption of time." Fast through a level means rejection; time spent at a level means both sides are comfortable there, that's where value is. Volume validates the activity, Villahermosa again: "Volume generation confirms that participants have created a new value zone where they trade comfortably." High volume at a price tells you that substantial trading took place there; whether that area becomes accepted value depends on the broader distribution of time, price, and volume. Low volume can indicate a thinner auction, but it is not by itself proof that a move will fail. Dalton calls this the missing context of market-generated information: fundamental information, earnings, policy, news, is external, delayed, and interpreted differently by everyone. Market-generated information, price, volume, and time at price, is pure, real-time, and generated directly by what participants actually did. Price alone is incomplete. Price discovers, time confirms, volume validates, always together, never just one.
Volume measures trading activity during a period. Open interest measures outstanding derivative positions. Where derivatives are involved, both can be useful, but they answer different questions and should never be treated as interchangeable confirmation.
The retail disadvantage, named precisely
And, on the discipline that separates survival from failure: "I did not know then what I learned later, what made me fifteen years later wait two long weeks and see a stock on which I was very bullish go up thirty points before I felt the time was right to enter." The retail trader watches Nifty go up strongly, everything looks bullish, he buys, right as the big player who drove the move is now selling to him. He watches Nifty fall hard, everything looks bearish, he sells, right as the big player is now buying from him. He's acting when price looks most obvious. A disciplined trader can wait through State 1 and act when the auction provides evidence of imbalance rather than forcing a directional view. That patience, the ability to wait for the auction to actually confirm something, is the entire edge.
Where the sources converge
None of these sources contradict each other, they're describing the same mechanism from different angles and different decades. Dalton names the mechanism itself, an auction searching for the price that facilitates trade. Murphy, Elder, and Lefevre together establish that price is a live consensus vote, not a caused effect, which is why it moves before the news does. Villahermosa explains the plumbing underneath: aggressive orders consume resting liquidity, while passive orders provide or absorb liquidity. Wyckoff and Dalton add a participant framework that helps explain how different time horizons and motives can produce the moves we see. Dalton's price-versus-value distinction explains why support and resistance actually work, it's memory, not magic. Grimes and Villahermosa describe the three states and the fact that most of the time the market is simply balanced with no edge to trade. The price-time-volume framework, backed by Dalton's market-generated-information concept, tells you how to actually read where the auction is in real time. Lefevre and Elder name the psychological trap that catches nearly every retail trader, acting on how price looks instead of what the auction is actually showing. Put together, that's the sentence this concept is sealed on: price goes up to search for willing sellers and price goes down to search for willing buyers. The same auction principle can be observed across markets and timeframes, although its expression differs with liquidity, structure and market design. Every chart pattern that follows in this curriculum—head and shoulders, flags, triangles, springs, upthrusts—is a different visual expression of the same auction process. Concept 2 is the mechanical foundation; later concepts show how that mechanism appears in structure, patterns and trade location.
