Elliott Wave Theory
EstablishedA claim that crowd psychology moves markets in a repeating wave structure at every timescale.
Ralph Nelson Elliott, The Wave Principle (1938) and Nature's Law (1946).
What it claims
On NEPSE the limit is data: wave counts need a long, clean history, and thin trading plus circuit limits rarely provide one. That market movement is not random but unfolds in a repeating pattern of five waves in the direction of the trend followed by three corrective waves, and that this same structure appears at every scale from decades to minutes.
How it works
- 1An impulse of five waves moves with the larger trend; waves 1, 3 and 5 advance, 2 and 4 correct.
- 2A correction of three waves — A, B, C — moves against it.
- 3The same structure repeats at every degree, so each wave contains a smaller wave set.
- 4Certain rules are treated as inviolable: wave 2 never retraces all of wave 1, and wave 3 is never the shortest.
- 5Fibonacci proportions are commonly used to estimate where waves may end.
The claim
Ralph Nelson Elliott, recovering from illness in the 1930s with time to study decades of price data, concluded that market movement is not random but unfolds in a repeating structure — and that the structure reflects the rhythm of crowd psychology swinging between optimism and pessimism.
His claim is unusually strong. Not that patterns sometimes appear, but that the market always moves in this form, at every scale, because that is how collective sentiment works.
Five up, three back
Five waves up, three waves back
A move with the larger trend unfolds in five waves: three advances (1, 3, 5) separated by two pullbacks (2, 4). The correction that follows unfolds in three waves (A, B, C).
- Wave 1 — the first move up, usually unnoticed and widely disbelieved.
- Wave 2 — a sharp pullback. Sentiment is still bearish; many conclude the rally has failed.
- Wave 3 — normally the longest and strongest. This is where the trend becomes obvious to everyone.
- Wave 4 — a shallower, messier consolidation.
- Wave 5 — the final push, often on weaker breadth than wave 3. Enthusiasm peaks here.
Notice how closely this maps onto Dow's three phases and Wyckoff's cycle. Three frameworks, invented separately, describing the same sequence of crowd behaviour.
The rules that constrain a count
Elliott Wave has few hard rules. Practitioners treat these three as inviolable, and a count that breaks one is considered wrong:
- 1Wave 2 never retraces more than all of wave 1.
- 2Wave 3 is never the shortest of waves 1, 3 and 5.
- 3Wave 4 does not overlap the price territory of wave 1.
Everything else — where a wave ends, which degree you are looking at, whether a correction is simple or complex — is judgement. And that is where the difficulty lies.
The honest problem
A framework that can explain any past move but produces disagreement about the next one is doing something different from forecasting. It may still be useful as a way of organising what you are looking at, and it produces a genuinely valuable habit: thinking about where you are in a larger structure rather than reacting to today's candle.
The practical guidance is to treat a wave count as one reading among several, to write down what would prove it wrong, and to be sceptical of anyone presenting a count with confidence. The rigour is in the alternative count, not the primary one.
How much weight it can carry
This is the method where honesty matters most. The wave count is decided by the analyst, and two competent practitioners routinely reach different counts on the same chart — which means it can explain any past move while giving little agreement about the next one. Treat a wave count as one reading, not a forecast, and be suspicious of anyone presenting it as certainty. Elliott's own books are still in copyright, so we cannot host them; the copies in our library are borrowable or purchasable only.

On NEPSE specifically
Wave counting needs a long, clean price history. Thinly traded NEPSE stocks with frequent circuit-limited sessions produce gappy series where counts are especially unreliable.
The vocabulary
The 6 terms you need to follow any discussion of this method.
- Elliott Wave Theoryalso: Wave Principle
- A framework proposing that crowd psychology moves markets in repeating five-wave advances followed by three-wave corrections, at every timescale.
- Impulse wave
- In Elliott Wave, a five-wave move in the direction of the larger trend, labelled 1 to 5.
- Corrective wave
- In Elliott Wave, a three-wave move against the larger trend, labelled A, B and C.
- Wave degree
- Elliott's idea that the same wave structure repeats at every scale, from decades down to minutes.
- Fibonacci retracement
- Horizontal levels drawn at set proportions of a prior move, used to anticipate where a pullback might stop.
- Retracement level
- A proportion of a prior move where price might pause or reverse. The commonly watched levels are 38.2%, 50% and 61.8%.

- Multiagent's model of stock market with p-adic description of prices↗
Viktor Zharkov · 2013
A new multiagent model of the stock market is formulated that contains four states in which the agents may be located. Next, the model is reformulated in the language of the functional integral containing fluctuations of prices and quantities of cash flows. It is shown that in the functional integral of that type descr…
