Elliott wave — structure of 5 impulse legs + 3 correction legs

Core idea
A complete trend cycle has 5 waves in the trend's direction (1·3·5 impulse, 2·4 correction) followed by 3 waves against it (A·C falling, B bouncing). This structure is fractal: each large impulse wave contains 5 smaller waves inside it, each correction wave contains 3 smaller waves. The reason it exists isn't mathematics but crowd psychology + the rhythm of big money moving in and out.
Careful: Read this line first — this is NOT the course's wave system
The vault has two systems that share the word "wave" but use different frames of reference — absolutely do not mix them:
| This system (the note you're reading) | The course's system | |
|---|---|---|
| Name | Classical Elliott (originated ~1930) | The teacher's system for reading waves via multi-timeframe RSI |
| What it counts | Counts wave numbers 1→5, A→C | Doesn't count numbers; asks whether the force is still there or gone |
| Note | this note, characteristics of each elliott wave | wave logic · the theory of wave progression · wave validity abc · the theory of a wave's nature |
| Source | a public video on the channel | the paid K2-2022 / K2023 course |
Both are the words of the same person, but said in two different places, and the course's system is the later, refined version. When writing a post about Elliott, use this note; when writing about the teacher's own system, use the other group of notes. Forcing wave-logic into an Elliott post is wrong — that's exactly the "close-enough note" mistake this vault has banned.
Details
The 5-wave structure in the trend's direction
In a main uptrend:
- 1 · 3 · 5 — impulse waves, moving with the bigger trend.
- 2 · 4 — correction waves, moving against it.
Pairing this with Dow theory: 1·3·5 is the primary trend, 2·4 is the secondary trend. And the condition for saying "the primary trend is still continuing" is still Dow's own condition — price has to break the previous impulse wave's high: wave 3 breaks wave 1's high, wave 5 breaks wave 3's high. Without that break, you have no right to name the next wave.
Three shape constraints
This is the part that checks whether your wave count is correct, and it matters more than the counting itself:
- Wave 3 is never allowed to be the shortest of the three impulse waves 1·3·5. The teacher stresses this point word for word — "never allowed." Wave 3 is usually the longest wave.
- Wave 1 is usually the shortest / weakest impulse wave of the three.
- Wave 4's low usually sits above wave 1's high. If wave 4's low breaks below wave 1's high, something is wrong with your count — go back and recount, don't try to bend the market to fit your label.
These three constraints have a reverse kind of value: they are not used to forecast, they're used to rule out a wrong count. That's their real purpose.
The A-B-C correction cycle
After the 5 rising waves, it enters a three-leg correction phase:
- A — the first falling leg, the main wave of the new falling trend.
- B — the bounce leg, corresponding to the right shoulder of a head-and-shoulders pattern. Doesn't break past wave 5's high.
- C — the continued falling leg, usually when the crowd first realizes the market has reversed.
Fractal nature — "big wave nests small wave"
A big wave always contains a small wave inside it, and it does so following an exact rule:
- A trend-direction wave contains 5 smaller waves inside it.
- A correction wave contains 3 smaller waves inside it.
A consequence few people notice: once the bigger trend has reversed to falling, A and C — which are the main waves of the downtrend — now contain 5 smaller waves, while B contains 3. In other words, "5 or 3" isn't tied to the rising/falling direction, it's tied to whether that wave is with or against the parent trend.
Why the market doesn't run in one straight shot
A mechanism the teacher explains purely through capital flow and psychology, not some mystical cycle:
- Experienced people with big money take profit after an impulse leg.
- Big money pulls out → price loses its support.
- Inexperienced people panic and sell regardless of price → price drops deeper than a "reasonable" level.
- Once selling pressure runs dry (most of the weak hands have already gotten out), a low forms, and only then comes the next impulse leg.
This connects directly to psychology's movement on the chart: each wave is an emotional state of the crowd, not just a number.
Limits on applying it — the teacher's own caveats
- Works better on medium- to long-term timeframes. Short waves get faked a lot, and counting waves on a small crypto timeframe is nearly meaningless.
- Crypto has bigger margins of error than stocks/forex because the market is smaller, easier for big money to manipulate.
- The teacher's closing line: financial markets are not 1+1=2. Every wave number and Fibonacci number is statistics + psychology, so (a) you have to combine it with other tools, (b) never go all-in on one price zone just because you trust one way of counting.
The relationship between wave 3's length and wave 5's
A live-trading observation, not a rule:
- Wave 3 runs more than 2 times wave 1 → treat the market as already "full" → wave 5 is usually short.
- Wave 3 only runs around 1.618 times wave 1 (under 2x) → wave 5 can become the longest wave.
The mechanism: if wave 3 has already run too far, buyers get wary and won't dare buy more, so wave 5 lacks fuel. If wave 3 hasn't satisfied buyers yet, the group pushing price still keeps buying.
Careful: Crypto isn't locked to that 2x ratio — wave 5 can still equal ~2 times wave 3. The teacher himself tells how he mispredicted the 2017 top using the 2.618 mark, and the market went much further than that; he says outright, "not even Satoshi come back to life could have imagined it." This is an example where the teacher admits he was wrong, kept as-is because it's exactly the lesson: fib is not a hard ceiling.
The practical takeaways from this:
- If you measure wave 3 as short → don't get complacent and close everything out early on wave 5.
- If you measure wave 3 as already very long → raise your guard on wave 5, keep the stop active, reduce position size.
Putting it into practice
- Only count waves on the medium/long-term timeframe. Skip the small timeframes.
- Count it out, then run the three shape constraints to try to disprove yourself. Violate one → recount.
- Confirm the impulse wave continues using Dow's rule: a closing candle breaking the previous impulse wave's high, wicks don't count.
- Use your position within the cycle to adjust your attitude, not to place a trade: being at wave 1–3 calls for a very different attitude than being at wave 5.
- The actual entry point still has to come from the real system (entry point), not from the wave-number label.
What the teacher stresses / common traps
- The biggest trap: counting the wave and then believing your own label. The label "this is wave 3" doesn't make price move. The three constraints exist so you doubt yourself.
- The teacher's stomach metaphor (if wave 3 eats a full meal, wave 5 only gets dessert) — noted here to convey the idea, Do not: do not carry this metaphor directly into a written post, come up with a different image.
- A BTC example the teacher uses: the entire 2017 rally was only wave 1 of a long-term cycle, and 2018 was correction wave 2. The specific high numbers he estimated out loud during the session are examples from 2018, not targets meant to be reused — only keep the method of his reasoning.
- Don't use Elliott to price the future. It's a topographical map, not a train schedule.
