Core idea
Resistance/support isn't one shared line for every timeframe — each barrier zone belongs to a specific timeframe, and the way to determine which timeframe it belongs to is to cross-check it against that exact timeframe's RSI pattern. Get the timeframe wrong and both the SL point and the TP zone go wrong with it.
Details
Law 1 — A wave on a given timeframe goes looking for that same timeframe's barrier
A wave on a given timeframe will go looking for the resistance/support of that exact timeframe.
This is how you determine the feasible TP zone. Reason: when H1's buying force pushes price up, it will run into the matching selling force at H1's own resistance zone → it balances out there.
- A downtrend wave on a given timeframe → the target is that timeframe's support zones.
- An uptrend wave on a given timeframe → the target is that timeframe's resistance zones.
- If, along the way, it pulls in buying force from higher timeframes too → it can break through and you're allowed to expect further. But for now, only set the target at the same-timeframe barrier.
- Conversely: a higher-timeframe wave usually cuts straight through a lower timeframe's barrier very quickly. Only when the market's force is too weak does it stop at a lower-timeframe barrier — which is exactly why the trade-management step is still needed.
Law 2 — A timeframe's barrier zone must correspond to that timeframe's RSI pattern
A timeframe's resistance/support zone must correspond to that timeframe's buying/selling force — in other words, correspond to that exact timeframe's RSI pattern.
How to do this on the chart: look at a high/low on price → turn on RSI for each timeframe → whichever timeframe has a pattern (RSI running to an extreme and getting blocked, or curling down and then bursting up) exactly at that spot is the timeframe that high/low is a barrier for.
- A spot where price just jerks down once and bounces right back up, without matching an M15 pattern → that's not M15 support; turn on M5 and see a segment that curls down and then up → that's M5 support.
- Some zones are overlapping barriers across several timeframes (e.g. both 15m and 30m) — those zones are stronger.
- In the past, looking only at price meant "identifying by eye." Looking at RSI tells you who — buyers or sellers — created that zone → so you can pin down exactly which timeframe the barrier belongs to.
Consequence: get the barrier wrong → the SL is wrong and the TP is wrong too. This is the root cause of a great many trades that get "stopped out and then the price goes the right way."
Reference resistance / support
Basic convention: price sitting below a barrier zone → call it resistance; price sitting above → call it support.
But in essence: resistance signals selling force, support signals buying force. So a zone created in the past by buying force (support) that price is now approaching from below going up hasn't ever proven there's selling force there → call it reference resistance, with lower validity than real resistance.
- It only gets confirmed as real resistance once price reaches it, forms a high, and turns back down.
- If price breaks through it quickly and then comes back to successfully retest it → it gets confirmed as support, adding buying force and continuing up.
Using "reference resistance" as an interim target is reasonable, but don't treat it as a certainty.
The definition the teacher pins down in one session (worth memorizing, since it settles every argument):
A support zone with value is a zone that once had a LOW. A resistance zone with value is a zone that once had a HIGH.
Direct consequence: an old support zone doesn't automatically turn into resistance just because price breaks it and comes back up. That spot only ever had a low, never a high → it's only reference resistance. It only gets confirmed as real resistance once price comes back, retests it and fails to break it — only then is there a high there. Before that point, absolutely don't close a trade rigidly just because "price touched an old zone"; you must also ask whether the next timeframe down (1D) still has upward momentum.
Along with this is the criterion for a genuine sideways breakout: price has to break strongly through resistance and only then build momentum above it. If it builds momentum and then corrects right at resistance, with unimpressive volume, the force isn't clear, it hasn't left the sideways range yet (see Volume & the DXY index).
When there's no barrier to reference
A price zone that has never appeared in history before (for example, BTC breaking its all-time high for the first time) → there's no concrete target. At that point the only option is to rely entirely on Managing trades and taking profit: as long as the daily timeframes still have upward momentum, just confidently hold, without setting a number in advance.
Practical rules for drawing barriers
- Drawing barriers is a skill, not knowledge: the theory packs into a very short summary, while being able to draw fast and accurately depends on your hours spent staring at charts. It's normal not to be able to draw them right away after learning this.
- For an important barrier zone: set an alert on the platform to be notified when price touches it, instead of sitting and watching the screen.
- Trade whichever exchange's chart you're actually trading on (prices differ between exchanges).
Correcting a common misunderstanding: "whatever timeframe the wave is on, that's the timeframe for SL/TP"
That statement is partly right but not optimal. The teacher's proper mantra is:
A wave on a given timeframe goes looking for the resistance/support of that exact timeframe.
The reason lies in force, not in convention: whichever timeframe a wave originates from, it's the buying/selling force of that timeframe's group of investors doing the pushing. To stop it you need a force equal to or greater → only a barrier belonging to that timeframe or above qualifies. A 12h wave going up that hits H1 or 15m resistance barely stops at all — a small-timeframe barrier can't hold back a big-timeframe wave.
Consequence for expectations: shorting off an H4 pattern means the immediate target is the H4 cluster's support. You're not allowed to jump your expectation down to a much higher timeframe's zone before that higher timeframe's force has actually shown up. A student asked "can I expect it to go down further?" — the teacher answered directly: there's no basis for that; right now there's only a barrier here, to go deeper you need force from a much higher timeframe.
A barrier is a ZONE, not a line
Resistance/support is a reference psychological zone. Anyone sitting there staring at "just barely crossing / almost crossing / already crossed" against one drawn line is going to lose for sure, because that line is something you drew — the market has no idea where it is. A real break = price moving clearly outside the zone + decent volume, not a candle wick brushing through.
The same logic applies to trendlines / price channels: connecting highs and lows is for observing a barrier zone, not for "sell when it touches the top edge, buy when it touches the bottom edge." When price reaches the zone, your job is to watch what the market shows there, then decide.
Putting it into practice
Process for determining SL and TP on a trade:
- Determine which timeframe the wave you're trading belongs to → that's the target timeframe.
- Draw the barrier zones of that exact target timeframe → that's the feasible TP zone.
- Identify the adjacent lower timeframe → find that timeframe's barrier zone by cross-checking against its RSI pattern → that's where you place the SL.
- Cross-check: is the high/low you're using for the SL actually on the timeframe you think it is, or is it actually from an even lower timeframe? (a common mistake: thinking it's an M5 low but it's actually an M1 low → SL too shallow, gets swept).
- Calculate the RR. If it's not good enough, either wait for a better entry point or drop the trade.
What the teacher stresses / common traps
- "If you identify resistance/support wrong, the feasible TP and the SL point are both wrong." This is a step you cannot be careless about.
- Trap: using a lower timeframe's barrier as the target for a higher timeframe's wave → closing too early, over and over.
- Trap: treating reference resistance as real resistance → over-expecting, or closing in the wrong place.
- Don't pre-place a TP order on the exchange. If you lock in a hard TP, a strongly running wave will get you closed out too early; the trade-management step should be the one deciding instead.
A barrier "already there" vs. A barrier "created while the wave is running"
This is the distinction that decides whether breaking a barrier means the wave has lost its validity or not.
| Definition | What breaking it means | |
|---|---|---|
| Barrier ALREADY THERE | High/low + a clear curling pattern, formed from the PRIOR trend | That timeframe's wave validity is LOST — the old trend has run out of permission |
| Barrier CREATED WITHIN THE WAVE | A wave running as one stretch (a single wave), which only then produces a high/low along the way | Does NOT prove the old momentum has died — the momentum can still remain |
An example the teacher uses: H1 is falling and there is already a clearly curled high from before → price pulls back up and breaks right through that same high = H1's downtrend validity is broken. Conversely, H1 is a single wave with no pre-existing high; only when it pulls back does it create a new resistance → breaking that new resistance does not mean the downward momentum has ended.
Tactical consequence: close early at the target timeframe's PRE-EXISTING resistance/support (e.g. 1D) as soon as the lower timeframe runs out of force — don't wait for price to finish breaking through before acting; by then you'll have lost too much profit.
The classic question, "what do you do if 1D has no pattern?" — if 1D doesn't have one but 3D / 1W does, build the trade around the timeframe that has the pattern. Sometimes you have to wait 2–3 months, and waiting is the correct move (cho doi chu dong).
A barrier is crowd psychology, and it has an expiry date
A barrier zone has nothing mystical about it: it's simply a price habit that's been imprinted on the crowd's mind, which is exactly why it can act back on the price line.
- An everyday example: rice once cost 100k/kg then dropped to 50k → the crowd defaults to "100k is expensive," forming the habit of "sell when it gets back to 100k." Gold once went from 30 million to 60 million → people with no knowledge still think "back to 30 means buy."
- A barrier zone's expiry date: the teacher estimates a barrier only keeps its reference value for roughly ~100–200 candles on the timeframe you're trading. Beyond that, the crowd's psychology has already changed and the zone loses its meaning.
- Repeating the timeframe law: 1W resistance is meaningful for a 1W wave; for H1 it's "no idea what that even is." Entering on a higher timeframe but taking the entry point/SL from a lower timeframe (or the reverse) = breaking timeframe discipline → profitable trade by trade, but not sustainable.
(A case from the session: a student was watching ETH's old high for TP/SL — the teacher said it's fine, if you're trading on exactly the timeframe that produced that high; it's wrong if you're entering on H1 but reading off a weekly-timeframe high.)
