Three sensitive points of a wave

Core idea
Within a trend on the target timeframe (say, H4), there are 3 moments when a pull from a lower timeframe is strong enough to bend the higher timeframe itself — that's when you have to be flexible, ready to exit. Outside those 3 moments, when the target timeframe's RSI is expanding strongly and the higher timeframes are in agreement, a correction on the lower timeframe is normal — at that point you must hold firm to the rule, not let lower-timeframe noise drag you around.
Details
Sensitive point #1 — when the target timeframe HAS JUST started running its wave
The target timeframe's own buying pressure hasn't shown itself clearly yet (RSI has only just budged, hasn't expanded, hasn't climbed solidly above 60).
- If the immediately smaller timeframe shows a clear falling pattern → very likely to pull the target timeframe back into a falling state → do not hold firm, exit right away to avoid the trade getting dragged back down.
- If the smaller timeframe only shows an ordinary pullback while the target timeframe still holds its rising state → the opposite: this is a point to add to the position.
Sensitive point #2 — when the target timeframe's RSI CONTRACTS with the 2 moving averages
A correction wave on the smaller timeframe pulls the target timeframe's RSI tight against the 2 MAs. This is a fork in the road: either the target timeframe corrects outright, or it opens up one more leg within the trend. Read it using the immediately smaller timeframe:
- H1 breaks the support zone → treat H1 as broken, its rising momentum has failed, it will drag H4 down right away → exit.
- H1 holds support, no selling pressure showing up → high probability H1 pushes higher again and pulls H4 into one more leg → hold.
Sensitive point #3 — when the target timeframe has gone TOO FAR
The "fuel tank" has run low: the target timeframe's RSI has run a long way, sitting in a high zone. At this point it only takes the smaller timeframe pulling down to easily drop the target timeframe straight into a correction → seeing the smaller timeframe lose force (its RSI opening downward, fast MA crossing below slow MA) is enough to close out — don't wait for the target timeframe to confirm it.
When you DON'T need to worry (allowed to hold firm)
When the target timeframe's RSI is wide open relative to the 2 moving averages (has spread, has slope), and the higher timeframes (H12, 1D) agree it's rising:
- Pulling it back down would take time, it can't drop right away.
- A correction on the smaller timeframe (m15, H1) is only natural, not a reversal signal.
- We have plenty of time to observe and weigh things — no need to react to every single candle.
Putting it into practice
Quick response table
| Wave position | Response | Which timeframe to track |
|---|---|---|
| Point 1 — just started | Be flexible, exit fast if the smaller timeframe shows a falling pattern | The immediately smaller timeframe |
| Point 2 — RSI contracting | Watch the smaller timeframe's support zone closely | The immediately smaller timeframe |
| Point 3 — gone too far | Close out when the smaller timeframe loses force, don't wait for the target timeframe to confirm | The immediately smaller timeframe |
| Outside the 3 points, RSI expanding + higher timeframes agree | Hold firm to the rule, ignore the smaller timeframe's noise | The target timeframe |
Flexible vs. consistent — by market shape
- Timeframes clearly agreeing (in phase) → absolute consistency: only buy and wait to buy, no shorting allowed (and vice versa). Don't "get creative" and add a trade the other way.
- Timeframes shifting out of phase / into a range → you have to be flexible: go long on the way up, short on the way down, repeatedly, short targets matching exactly the timeframe you entered on, and pocket a profit of a few hundred points. The goal is to make money, not to argue right or wrong with the market.
- The most dangerous thing is being out of sync with the switch-over: the phase has already changed but your thinking is still stuck in the old phase (still expecting the old trend's far-off target) → you get caught in a trade, take a loss.
Characteristics of a range phase (need to change tactics)
- The smaller and larger timeframes tend to be overlapping waves, rarely a clear pullback wave → there's almost no wave structure to hold on to → use it if it's there, skip it if it isn't, don't sit around waiting for a pullback.
- If the smaller timeframe has rising momentum while the timeframes above it are out of phase, it's very prone to failing → the moment you see them all get dragged down together, close out immediately, don't wait for a pretty signal.
- Support/resistance on the smaller timeframes gets tangled and dense → an upward wave has a very hard time of it, R:R is poor → either skip it or take a short profit.
- Trading off a small timeframe (30m), the target is exactly that timeframe's resistance — don't secretly hope it pulls H4/H12 up too.
FOMO-bait waves during a higher timeframe's sell-off When a higher timeframe is selling off and price shoots up sharply for a stretch: that wave usually sells off very fast, rarely with a pullback → you have to exit/reverse using signals from a very small timeframe (m3, m5); waiting for m15's pullback is already too slow, everyone can already see the signal is weak.
Weakening signals used for flexible decisions
- An m15 candle with a full body, high volume pushing up; the next candle has volume that's still high but fails to push higher, with a long wick pulled back — selling pressure has already come into that price zone.
- M1 fails its rising momentum and drags M5 and m15 into agreeing to fall → market force weakens immediately, even though all 3 timeframes still "have rising momentum" in theory.
- If the whales want to push price, they push fast and decisively so outsiders miss the chance — they don't push half-heartedly. A genuine resistance breakout happens very fast; hesitant movement = no real intent to push.
Things that must NOT be counted as a signal
- One RSI candle stabbing below the 2 moving averages and then snapping back up: meaningless. Only when the fast MA crosses below the slow MA and holds for a few candles does it confirm a change of state.
- When the RSI on a timeframe that has a pattern (say, H1) still holds its rising state, you're not yet allowed to think the other direction, no matter how much the smaller timeframe flickers.
- Inside a range zone, every RSI cross up or down is worthless as a signal.
The market running fast or slow
- It runs fast when the timeframes have a clear trend (RSI + 2 MAs expanding, with slope) — regardless of whether they're in phase or out of phase. If both sides are strong while out of phase, the "fight" ends very fast.
- It runs slow when the timeframes have no trend, hovering between 40–60 — like two boxers where one just guards and won't throw a punch, the fight drags on.
What the teacher stresses / common traps
- This is knowledge that only shows up in a live-trading session, it's not in the curriculum — write it down carefully.
- The biggest trap: applying it mechanically. "I'll wait for H1 to finish correcting before I close H4" — while H1 and H4 are overlapping waves, H1 going down means H4 goes down too; waiting like that loses you all the profit.
- The opposite trap: getting sucked into the noise of a timeframe that's too small during a range → your psychology wobbles, you exit early while the timeframe with the actual pattern is still perfectly valid.
- After a big winning day, the excitement can easily push you to jump straight back into trading during a noisy stretch → giving back all the profit. Know when to go in, know when to stay out; know when to press forward, know when to pull back.
- Real market signals actually always show up clearly and unhurriedly — 9 out of 10 waves give a signal to enter. The problem is that we ourselves rush, afraid of missing the wave.
