Identifying the range zone

Core idea
A range isn't a single state — it has two completely different shapes: a range because there's no buying/selling force, and a range because the buying/selling force of different timeframes is contesting each other. The value lies in identifying it BEFORE the range zone forms — spotting it after it's already gone sideways has no trading value left. Every range zone always belongs to one specific timeframe, and only by correctly determining "which timeframe's range this is" can you choose which wave to capture inside it.
Details
Base principle: only trade a timeframe that HAS A PATTERN
- Whichever timeframe's RSI has a pattern (accumulation, narrowing then opening, with a slope + expansion of the two moving averages) → that timeframe has buying/selling force being prepared → only then is there data to enter a trade.
- Whichever timeframe is ranging = "the fence-sitter": if another timeframe says up it goes up, if it says down it goes down → exclude it from the meeting, don't use it to make decisions.
- An important distinction: a timeframe currently falling/rising doesn't mean that timeframe has a wave. You have to check whether the stretch before it had an accumulation pattern. If it was ranging before and got dragged along by another timeframe → that wave isn't its own → no entry point, no risk point, no target.
Shape 1 — A range because there's NO buying or selling force
Analogy: a market of 100 people where 90 go home, leaving 5 buyers and 5 sellers.
Signs once it has already happened (on that timeframe's own RSI):
- RSI has no clear up/down pattern; the two moving averages go flat, narrow, no slope, no expansion.
- RSI keeps crossing up and down and sits entirely within the 40–60 zone (the buy/sell force balance zone).
The set of 3 conditions to IDENTIFY IT IN ADVANCE (≈80% probability a range is coming):
- The nearest RSI low doesn't punch below 30 → selling force isn't strong.
- The nearest RSI high doesn't rise above 70 → buying force isn't strong either (it looked like it could pull higher but turned out to be ordinary).
- RSI + the two moving averages then narrow and tuck into the 40–60 zone.
Note: the order of high/low can be reversed (high first, low after) — it still counts. If you only have conditions 1 and 2 and RSI hasn't tucked into the balance zone yet, then you can't conclude yet — it could still be a mild build-up process of buying force.
Shape 2 — A range because timeframes are CONTESTING each other
Analogy: a market of 100 people, 50 buying – 50 selling, both sides strong but balanced against each other.
The key difference: in this shape, RSI STILL HAS A TREND, it doesn't sit within 40–60. Because RSI reflects buying/selling force, and both sides' force is strong. It's only price that goes sideways — within a flat channel, an upward-sloping channel, a downward-sloping channel, or a triangle.
The rule for determining which timeframe a range zone belongs to:
A small timeframe has a pattern + is out of phase with the trend of the larger timeframe → this forms a sideway price range BELONGING TO THAT SMALL TIMEFRAME.
Example: 2D has a nice up pattern, but 1W is in a downtrend and its two moving averages are still expanding → 2D can't pull 1W along → price goes sideways → this is 2D's range zone (not 1W's — 1W at that point is still within its own down-wave/correction).
Similarly: 1D wants to roll up but 1W is still expanding → 1D's range zone → inside it, only trade H1/H4 waves.
This rule runs all the way down to intraday timeframes too:
- H4 wants to go up + 1D is still expanding down → H4's price channel / range. Inside it are H1's up–down waves.
- H1 wants to go up + H4 is going down → H1's range.
A voting metaphor: the whole class raises hands, 1D says down, H4 hasn't finished its upward force, only H1 raises its hand for up → the majority is still down. H1's force is out of phase, so it can't "dress" the higher timeframe in its trend — it's only enough to create a price channel.
A practical consequence — this is where people often misread it backwards: being out of phase with the timeframe directly above doesn't mean entering a trade is forbidden. Shorting H1 is still playable when H4 is out of phase (H4 wants to go up), provided H4's upward force is still weak relative to 1D, which is expanding down. What has to change is your expectation, not the decision to enter or not:
- trade H1's pattern inside the expected H4 range channel — meaning the target stays within the channel's edges;
- don't expect H1 to pull far enough to break 1D;
- if an even smaller timeframe (M5) completes its downward momentum weakly, that's even more confirmation that a range stretch is coming, not a running wave.
Careful: Read on to the "Special case: H4 out of phase with 1D" section at the end of this note before drawing conclusions — what's being relaxed here is expectation and target, not the higher-timeframe-agreement rule.
The general advance-warning sign: OUT-OF-PHASE among the higher timeframes
When you see an out-of-phase/mismatched phenomenon appear among the higher timeframes (a smaller timeframe wants to roll up, while the larger timeframe is still expanding down — or the reverse), combined with the lower timeframe having no more momentum to keep pulling in the old direction, a range zone is almost certainly about to appear. This is the earliest forecasting signal.
At this stage, every trading system gives a 50/50 answer — that's exactly the trait of a range, not the system being broken.
The width of a range zone: don't try to guess it early
- In the first few waves, it's impossible to know whether the range will be a triangle, a flat channel, or a sloped channel. Don't draw it in advance and cling to it.
- The only thing you know for sure: there will be a range zone. The upper/lower edges get determined gradually from the support/resistance created by those first few waves themselves, combined with wave-nature theory (an up-wave closes when its upward momentum runs out → the upper edge; a down-wave closes when its downward momentum runs out → the lower edge).
What buy/sell-force ratio produces which price shape
| Ratio | Price shape |
|---|---|
| 80/20 or 90/10 (total dominance) | A real trend — main-wave/correction-wave structure not exceeding 0.5, a single wave on the higher timeframe |
| 60/40 or 55/45 tilted toward buying | An upward-sloping price channel (tug-of-war, not an uptrend) |
| 45/55 or 40/60 tilted toward selling | A downward-sloping price channel |
| ~50/50, both sides weak | Range shape 1 (RSI within 40–60) |
| ~50/50, both sides strong | Range shape 2 (RSI still trending) |
An upward-sloping price channel is NOT an uptrend. It's only a balance zone where buying force is just a bit stronger (10 sellers / 11 buyers).
Distinguishing concepts that often get mixed up
- An up-wave ≠ an uptrend. An up-wave is a single wave. An uptrend has to build a structure (main wave – correction – main wave, progressively higher highs and lows) on the lower timeframe.
- A correction wave = a bounce wave ≠ a downtrend. If there was an up-wave before it with guaranteed momentum → the down leg is a bounce wave → your position is wait to buy. If it's a genuine downtrend → your position is wait to sell. Confusing these two means confusing both the target and the trade direction.
- A down-wave ≠ a downtrend. A down-wave is just a wave heading down, with no guaranteeing force beforehand. A downtrend has to have a down-accumulation pattern + downward momentum — downward momentum is what guarantees the "bounce up, then keep falling" scenario.
- An up state ≠ an uptrend. An up state = RSI is sitting above the two moving averages. An uptrend = the two moving averages expand + have a slope, RSI breaks above 60 and holds it. While in an up state, don't guess whether it'll become a trend or turn back into a range.
A sharp jerk WITHIN a range ≠ the higher timeframe's force coming back
Within a narrow H4 range (about 500–700 points in that session) with H1/H4 RSI sitting in the 40–60 zone, price jerking up and down very fast within a few 15m candles is a normal thing — that's the small timeframe's force, not the higher timeframe's buying/selling force coming back.
- A sharp jerk during a range easily makes people think "buying force is back" and they go long chasing it → the rate of getting stopped out is very high.
- The only condition that changes the conclusion: has H1/H4 resistance been broken yet or not. If it hasn't broken, you're not allowed to guess.
- The motto of this session: trade what you see — if the candle hasn't closed and resistance hasn't broken, don't make up a story. The teacher phrases it as a dialogue with the market: "if you haven't broken this zone, I don't have an opening, don't try to fool me." (Don't predict the market — "to make money, you don't need to know what happens next" — don't forecast the market)
The teacher corrects the terminology on the spot: STATE ≠ TREND
A student called the weekly timeframe "a weak uptrend"; the teacher immediately corrected it to "an up state, currently at sensitive point 2". The boundary:
- RSI sitting above the two moving averages = an up state. To call it an uptrend, RSI has to open a slope / expand outward. Same on the down side.
- Why you have to be strict about the wording: mistakenly calling something a "trend" when it's still just a state drags along a wrong expectation — you'll follow it as if there's a trend, while the market hasn't actually allowed that yet.
- Applied to a price channel: when 2D is contesting 1W, you know for sure there will be a range, but don't draw the channel in advance — wait for the first 2 highs and 2 lows. The channel stays valid for as long as 1D/2D keep holding an up state; once those two timeframes turn to a down state, drop the channel, don't try to hold onto the old drawing.
The figure you must write in your notebook: 70–80% of the time is range
The teacher says this verbatim in the professional-mindset session and makes students write it down, "no arguing with it": review any timeframe, at any period, and you get the same ratio — 70–80% of the time the market is ranging, only 20–30% has a trend.
A harsh consequence: if you fire off 100 trades on signal without distinguishing the market shape, about 80 of those shots land in a range zone. In other words, ~80% of your loss rate is already decided before you even get to whether your entry skill is good or bad. This is why "switching mindset by market shape" matters more than "finding a nicer-looking setup."
Careful: Don't turn this into a rigid formula: in other sessions the teacher says 80/20, in this one 70–80/20–30 — same idea, it's a time-distribution rule, not a fixed parameter. Also note this is a different ratio layer from the 80/20 in Risk wave vs profit wave (the 80/20 rule) (risk wave vs profit wave — that layer is about risk wave vs profit wave). The two layers are related but not identical.
Naming a range after its correct owner
A range always belongs to one specific timeframe, and how you name it has to match the timeframe that has the pattern / the timeframe that's out of phase. Example: 1D/2D's up pattern out of phase with 1W, which is falling → the sideways zone born there is 1D/2D's range, not "the weekly range."
Get the owner wrong, and everything downstream goes wrong too: the wrong edges, the wrong timeframe to trade inside it, the wrong level of expectation.
Don't guess which timeframe will run — listen to what the market is telling you
A real situation: 1W has a nice up pattern but 2W is still expanding down. The question "will 1W just go up, or does 2W have to narrow first?" is a question with no answer at that point in time — asking it already means stepping into forecasting.
A trader's job is to have a conversation with the market: listen to what it's telling you, not judge what it's about to do. The bottom-line principle: whichever timeframe wants to run still needs a catalyst from the small timeframe; if the small timeframe is weak, exit and wait for the next wave — there's no need to pick a side in advance.
Putting it into practice
- Scan in order from the highest timeframe down to the smallest (1M → 1W → 3D → 2D → 1D → H12 → H8 → H4 → H2 → H1 → 30m → 15m), and for each one answer: does it have a pattern? (not "is it going up or down").
- Any timeframe whose RSI is hovering around 40–60, with the two MAs tangled together → cross it off, don't use it to make decisions.
- For timeframes with a pattern: check whether they're out of phase/in phase with a higher timeframe that's 3–7 steps larger → if out of phase, determine that this will be that timeframe's range zone.
- Apply the set of 3 conditions (low > 30, high < 70, RSI narrowing into 40–60) to forecast a shape-1 range zone in advance.
- Once you've determined "which timeframe's range this is" → only then decide which timeframe's wave to capture inside it (see Range vs trend tactics, range vs trend tactics).
What the teacher stresses / common traps
- Identifying it in advance is what has value. Wait until RSI is already clearly tangled within 40–60 before naming it, and you've already lost a whole stretch — "what's the point of even discussing it."
- A range zone produces a huge amount of noisy signals. Knowing in advance is for (a) no longer holding expectations, (b) not rushing to buy/sell. Not knowing in advance → buying every cross-up, selling every cross-down → buying the top, selling the bottom → blowing up.
- Even someone who only trades trends absolutely must know how to identify a range — so they can stay out. Earn 10 dong during a trend and lose 6 dong during a range, and you're only left with 4; if you rest at the right time, you keep 8–9.
- If you can't determine the range zone, then no matter how tough your psychology is, your profit still isn't optimized: someone who captures both up and down within the range can rack up tens of thousands of points, while someone who "holds to be safe" only captures one stretch and then buys the top again.
- Don't understand this mechanically like 1+1=2. For example, RSI dipping below 40 for one candle then springing straight back up still counts as being within the range zone. All the lines on the chart are human psychology, and you have to read them flexibly.
- What you see, not what you think. Ask "what IS it doing right now," not "what's it ABOUT TO do." RSI having already traveled far ≠ RSI is about to reverse.

BEING OUT OF PHASE WITH A HIGHER TIMEFRAME PRODUCES A RANGE — which timeframe does it belong to?
A source of range that newcomers often misread as a "weak trend": H4 has an upward pattern while 1D is heading down. The two out-of-phase forces don't cancel each other out — they give birth to a range zone, and that zone belongs to the H4 timeframe, that is, the smaller timeframe of the pair.
The practical consequence is very simple: within that range, only go looking for waves of a timeframe SMALLER than H4 that has a clear pattern before entering. Don't trade as though H4 has a genuine uptrend.
Why this is a "low-value" range: it isn't born from an accumulation of force but from a tug-of-war between two timeframes, so its edges are usually narrow and easily broken unexpectedly once the higher timeframe reclaims control.
Forbidden: calling it early in the opposite direction — the criteria set
A paired mistake: seeing M15 weaken and shorting early, while H1 is still green and H1's two moving averages are still expanding far apart. A small wave rolling up–down while the timeframe above still has force is just noise — not data.
A valid short point is much more solid once it meets:
- H1 starts NARROWING the gap between its two moving averages (the higher timeframe's force is running dry), and
- M15 has run out of upward momentum, or has already built a series of progressively lower highs.
Only then do you "hang" the trade at the top of the bounce. The practical metric here is the width between H1's two moving averages — it's a clearer gauge of whether force remains or has run out than candle color or the feeling of "it looks weak now."
Careful: Don't teach the original knowledge backwards
The teacher stresses this point specifically: the foundational theory from the very first session — "to trade H1 downward, you need a higher timeframe to agree" — remains fully true. The H4-out-of-phase-with-1D case isn't an exception that voids the rule, it's simply a description of the state produced when two timeframes oppose each other. This understanding has to come from real trading experience and only then be reflected back onto the theory; anyone who shortcuts this part very easily draws the wrong conclusion, something like "turns out you don't need higher-timeframe agreement after all."
