A market is an auction that never pauses during the session. Every tick is the crowd advertising a price and waiting to see who answers. Understand that one sentence and most of what looks like chaos on a chart turns into a process you can read.
Auction market theory is the framework behind that sentence. It does not predict where price is going. It explains what price is doing right now, and why, in a way that a rule can act on. Here is the whole idea on one page.
The market moves price up to advertise for sellers and down to advertise for buyers. A high price is an advertisement: the market is asking, will anyone sell up here? If enough volume trades, the answer is yes and the advertisement worked. If price rises and almost nothing trades, the advertisement failed, and price tends to fall back to where business actually gets done.
So price tells you where the market is looking, and volume tells you whether the market agreed. Price without volume is a question. Price with volume is an answer.
Price is the market advertising for the other side of the trade; volume is the market answering. A move on heavy volume is accepted and tends to hold. A move on thin volume is rejected and tends to reverse. Almost everything else is detail.
When buyers and sellers agree, they trade, and they trade the most at prices both sides consider fair. Stack up a session's volume by price and it forms a shape: a fat middle where most contracts changed hands, thinning out toward the extremes. That fat middle is value.
Three landmarks come straight out of that shape.
The full mechanics of reading that profile, and of building it, are in volume profile: POC, value area and LVN.
The auction has two states, and telling them apart is most of the job.
A trend is not a mysterious force. It is the auction failing to find sellers (or buyers) and having to keep moving to attract them, until it reaches a price where business picks up again and a new balance forms.
The ideas are old, but the modern language comes from the trading floor of the Chicago Board of Trade. J. Peter Steidlmayer developed Market Profile there in the 1980s as a way to organize a day's trade by price and time. James Dalton then made the framework readable for the rest of us, and if you take one book from this article, take Dalton's "Mind Over Markets." None of this is a secret indicator. It is a way of describing what an auction does.
The plain-English version of how the Algomyth engine reads the open and acts on it, step by step, is on one page.
Auction theory matters here because it gives a machine something concrete to read that is not a lagging indicator. A moving average tells you what price already did. The auction tells you what price is doing: advertising, and being accepted or rejected, in real time. That distinction is the whole argument in order flow versus indicators, and it is why systems built on the auction react to participation rather than to a smoothed line.
The open is where auction theory earns its keep. At 9:30 AM ET the US cash market opens and the day's volume arrives, which means the market has to re-advertise: the prices that were fair yesterday may no longer attract the other side. A fast, one-sided move away from the previous area of value, on real volume, is the auction telling you it has rejected the old balance and is hunting for a new one.
That is the single window the Algomyth engine trades. Once a day, in that opening move, the system takes one position, places its stop and its target in the market at the same instant, sizes the target at three times the risk, and never holds anything overnight. The auction read is what defines the setup; the rules are what remove the hesitation. The full mechanism, without the jargon, is in how it works, and the wider context of trading the session open is in the 9:30 AM ET window.
It will not tell you the next tick, and it will not turn a losing plan into a winning one. It is a lens, not a crystal ball. The auction can advertise, get answered, and still reverse ten minutes later because new information arrived. What the framework gives you is a reason for what you are seeing and a consistent way to act on it, which is exactly what a rule needs and exactly what discretion tends to abandon under pressure. For how a rule-based reading of the market fits into actually trading the contracts, see how to trade futures.
It is the idea that a market works like a continuous two-way auction. Price rises to advertise for sellers and falls to advertise for buyers, and volume shows whether the advertisement was accepted. Where lots of trade happens, the market has found value; where little trade happens, price was rejected and tends to move on. It is a way to describe what price is doing, not a prediction of where it will go next.
The point of control, or POC, is the single price at which the most volume traded during a session. Think of it as the fairest price of the day, the level where buyers and sellers did the most business and spent the most time. Traders watch it because price often returns to areas of heavy past trade, and because a market accepting or rejecting the POC says something about whether the current balance is holding.
They are closely related but not identical. Auction market theory is the underlying concept that markets are two-way auctions seeking value. Market Profile, developed by J. Peter Steidlmayer at the Chicago Board of Trade, is one specific tool for organizing a session's trade by price and time so you can see that auction on a chart. Volume profile is a related tool. The theory is the idea; the profiles are ways of drawing it.
No, and any source that claims it does is overselling it. Auction theory explains the mechanics of what is happening right now and gives you a consistent framework for reacting, but new information can reverse an accepted move at any moment. Its value is in giving a rule-based system a clear, repeatable read of participation rather than a lagging signal, not in forecasting the next candle.
By turning the read into fixed rules. Instead of a human judging whether a move away from value is being confirmed by volume, the system checks defined conditions and acts the same way every time. The Algomyth engine applies that kind of read once a day in the 9:30 AM ET window, entering with a stop and target already placed and the target set at three times the risk. The theory defines the setup; the code removes the hesitation that discretion introduces.
Everything we write comes back to one idea: verify, then decide. The live terminal exists for exactly that.
