Core idea
After finishing the theory portion, most of the knowledge needed to analyze the market is already sufficient — the remaining bottleneck isn't "learn more tricks," it's forging mettle, discipline and psychology through live combat. This is the phase-shift point many people miss: they keep studying half-heartedly, waiting for "new material," instead of seriously drilling the part that actually decides win or lose.
Details
1. The LEARNING TO DRIVE metaphor
Teaching someone to drive means teaching all the basic mechanics: clutch and gas, releasing and engaging the clutch, shifting gears up and down, holding the wheel, steering. Once that's covered, that's enough to drive the car. What's left isn't waiting to be taught a "new gear" — it's:
- Getting behind the wheel yourself, building muscle memory, reacting to real situations (a car cutting across, blind spots, high speed).
- Forging discipline while driving and steady nerves on the highway.
A common trap: studying half-heartedly, telling yourself "I'll get serious once we reach the 'new gear' lesson" — but at this point the analytical knowledge is already sufficient; only a few market shapes remain as variants to watch for. Studying half-heartedly wastes the time and effort of the whole process.
2. Four things left to forge (knowledge isn't one of them)
What must be drilled from here on:
- Experience — applying knowledge to the real market is what gives you something to fix.
- Investing mettle.
- Combat psychology while holding a position.
- Self-discipline.
Only practicing against the real market reveals where you're wrong so you can fix it — endlessly re-reading theory never produces these four things (the same logic as body–mind–wisdom in Combining knowledge with tactics — why knowing still isn't enough to stop you losing: only the body can be actively forced into it; mind and wisdom get pulled up along with it).
3. "Haste makes waste" — the faster you rush, the faster you die
In the early stage of learning new knowledge, everyone is eager to apply it and make money fast. But in this profession, the more impatient you are, the faster you die; the more you rush, the less you achieve. Anyone still itching to jump into 5m/15m waves to "trade to their heart's content" shouldn't be asking, not long after, why they keep trading without any profit to show for it — that's exactly the consequence of skipping the step of training mettle and discipline.
4. You need REST PERIODS to preserve your profit
One concrete expression of mettle is knowing when to stop. Trade nonstop with no rest and the result is "made a little money here, burned it all there" — and in unclear stretches you don't even make money, you just rack up small stop-losses that breed irritation and cost you your composure. Only by keeping a rhythm of rest with the market does the account grow steadily and do you keep your calm.
A real-case warning: a student with solid knowledge, solid tactics and reasoning, waiting for a textbook-correct short entry — but because they used excessive leverage and kept jumping in and out of the 15m noise, just 2 stopped-out 15m trades wiped out the entire account. Being right on the knowledge still gets you killed if you let go of discipline and risk management. See also Timeframe consistency (the profit-generating strategy), Stress in trading & capital strategy to reduce pressure.
5. Don't "get creative" with the system at this stage
The entire trading system has already been distilled into the most correct form to share; the practice stage is about following it faithfully, not inventing your own version. Improvising freely before your mettle is solid only wrecks a framework that was already correct (compare "flexible ≠ arbitrary" in Getting Comfortable with Uncertainty and Three sensitive points of a wave).
6. Don't bring an OLD SYSTEM into the course
- Everyone who comes to learn is someone who hasn't achieved steady profit with their old system. So during this stage, don't bring any old knowledge or method into your analysis — use only what you've learned so far. (The teacher: all systems ultimately turn out to be "the same at their core," but mixing half of one with half of another produces no coherent system at all.)
- This is the same rule as point 5: no inventing your own parameters. Getting creative before you're roughly 80% fluent means "who knows if it's even right."
- If you haven't mastered this system yet, then you also shouldn't read books on other technical-analysis systems — it will just confuse you. Later on you'll see for yourself that they share the same core (see the reading-list section of tang bang chim trading).
7. Learn in the right ORDER — don't ask ahead before it's time
- Students often message asking about money management / discipline / trading ranges as early as sessions 5–6. The answer: not yet, get the foundation down first.
- The difficulty scale the teacher uses: trading trend = elementary/middle school, trading range = high school — same body of knowledge, but a different way of wiring your thinking and a different psychology. Skipping ahead to "high school" before finishing "elementary school" is self-inflicted failure.
- The consequence for what this stage is aiming at: this stage is about KNOWLEDGE, not yet about profit. Money is a result the market pays out once you've learned to see clearly — not something you go demand up front.
8. The goal is making money, not taking many trades
- The more trades you take, the higher your odds of running into risk. A whole week with no trades at all is normal, not a sign of laziness.
- A metaphor: wait for the school of fish to swim past the boat before casting the net; cast too early and you've just wasted bait.
- The easy part is spotting a pattern on H1/H4. The hard part is having enough patience to sit and wait for the pattern to form. The hardest opponent is still yourself, not the market.
- When reviewing: add up the gains from correctly-played trades, subtract the losses from carelessly-entered trades → most people who run this calculation are surprised to find that most of their profit comes from taking fewer trades.
9. The thing harder than entering is NOT ENTERING — Hau's case
Once you've finished learning, spotting a pattern, whether momentum exists or has run out, whether there's agreement or not — all of that is straightforward. The account still isn't profitable because you're still taking unclear trades and eating stop-losses that were never necessary. The teacher's summary: entering a trade is easier than not entering one.
Hau's case (a student, during a ranging month): took only 6 trades the whole month, each risking exactly 1% of the account, followed the rules 100%, got stopped out zero times, and finished up roughly +40% on the account. The teacher's comment: taking only 6 trades in a month, this early in learning, is very hard — early on, some people were taking 10 trades in a single day.
The mackerel-net metaphor: if you want to catch a 10 kg mackerel, bring a wide-mesh net to catch mackerel. Cast that same net at a school of small carp and the fish slip straight through the mesh, and you've wasted bait too. Picking the wrong kind of opportunity for your system ruins things on both ends.
The three remaining fears once the system is fully internalized: (1) fear of missing the wave, (2) fear of closing too early, (3) (the caption reads "fleo" — unclear audio, most likely fear of getting stopped out; check again to be sure). The cure passed down from earlier cohorts: face it head-on until you go numb to it, and adjust your position size to your own "financial thermometer."
How to build inner strength before trading real money: run backtests split into two phases (one ranging, one trending), work every wave through the full 5 steps as if it were a real trade, and log every variant you encounter (Hau tracked more than 20 ranging cases plus various momentum-failure cases). Backtesting is how you compress the time, tuition, and "price paid to the market." The teacher's note: backtesting a trend is easy; the hard part is holding a winner — ranges are where the real practice is needed.
On the style of catching tops/bottoms inside a range's boundary: you need the parent timeframe's pattern plus agreement from 3 smaller timeframes all rolling together; if they're out of phase, exit immediately — don't expect to capture the whole H1 move. And while a wave is running strongly, catching tops and bottoms is forbidden — you must wait for it to decelerate, stop, and finish forming the opposing structure.
10. The 10/90 ratio — the teacher's closing line for the session
"The knowledge and experience I share with you all only makes up 10%. The other 90% depends entirely on how hard each of you tries and how diligent you are — how much you practice, how much you experience, how much you apply it to the market."
An observation that goes with it: across every cohort, the people who get good results are always the ones who are extremely diligent, not the ones who are smarter. This profession isn't hard in some secretive way, and it isn't easy in a sloppy way either — results come to whoever repeats the right actions. Hau's "one month, the two of us as a couple made almost a billion" number is a consequence of backtesting + 6 clear trades + closing fully whenever the pattern ran out, not some new trick.
"Able to do it" is different from "able to teach it" — and why 10 sessions of knowledge need 50 sessions of practice behind them
The teacher shares his own naive moment from the very first cohort: he thought that because he himself was good, teaching 7–10 sessions would be enough for people to actually do it. Wrong. Correct knowledge without practice alongside it produces a very low success rate — he even says plainly that teaching that way is close to fraud, because the students can't actually apply it.
The structural reason, and this is the expensive part: one piece of knowledge, A, turns into variant A′ in one phase of the market, and A₃ in another. Ten sessions of theory only teach the original "A." You only encounter the full range of variants by going through the market across enough of its different forms — and that's the job of the other 50 sessions.
Tying straight back into this note's main point: if knowledge is something you learn once and you're done, then what's left really is practice, correction, and mettle — not hunting for new material.
No practice means no questions — and no questions means nothing gets fixed
The chain of causation the teacher lays out:
no practice → no questions → nothing gets corrected → no results → blame the teacher instead.
So ask as much as possible, and hiding your ignorance only hurts yourself. The mirror image of that: the cohort of past students who used to ask questions until 1–2 in the morning, 5–6 hours straight — that's the group that got results.
How much chart-watching is enough (once you're good)
A useful number to picture the destination, from the opening session: once fully skilled, the teacher himself looks at charts about 30 minutes a day (his main daily activities are reading and exercise).
- Trading H1: check about once an hour, roughly 30 seconds each time — because the scenario is already mapped out, you're just checking whether the confirming/invalidating condition has happened.
- Trading H4: check once every 4 hours.
- Only the early stage (roughly the first 6 months of learning) needs close, constant attention.
A rule that comes with this: never analyze for more than 30 minutes a day. Sitting there longer doesn't make the analysis any better — it only breeds more expectation (see kiem soat cam xuc truoc khi kip suy nghi).
Putting it into practice
- Remind yourself: from here on, your problem is no longer "lack of knowledge" — it's discipline/psychology. Whenever you lose, look there first (use but giay nen).
- Force yourself to practice against the real market (demo, in the early stage) to have something concrete to fix, instead of re-reading theory for the nth time.
- Build in rest periods deliberately: when the market phase is unclear, shut the machine off and switch to reviewing notes/money management.
- Don't raise leverage to "go faster"; keep the stop-loss at ≤1% of the account per trade.
- Do the system exactly right before thinking about variations on it.
What the teacher stresses / common traps
- The "wait for new material before getting serious" psychological trap — while the knowledge is already enough to start drilling right now.
- The impatience trap: wanting fast profit → jumping to a smaller timeframe → haste makes waste.
- The leverage trap: correct on the knowledge but high leverage + no rest = one or two bad trades wipes out however long it took to build up your gains.
- This is a phase that's light on volume of knowledge but heavy on drilling — sessions get shorter (an hour and a half), mostly spent sharing lessons learned with each other.

Two kinds of "creativity" are the same disease
1. Inventing new theory when the wave slows down
A recurring pattern: study for a while, hit a stretch with a trend and trade it fine; a few days of a slow wave and people start making up new theory for the no-force phase. On the surface it looks like progress (digging deeper research!), but underneath it's really thinking you're smarter than the market — building a system that supposedly explains every market shape.
The teacher's blunt counter:
No system explains a phase with no buying force and no selling force.
Because simply put, there's nothing there to explain. The root of this behavior is greed, fear and FOMO — the need to be in on every single wave. The teacher's closing line: the market is simple; the complexity lives in your own emotions and thinking.
How to self-diagnose: notice yourself trying to build a new rule for one specific market state → immediately ask yourself, "do I want a trade, or am I actually seeing evidence?" (see Observe – Contemplate – Result (Quan – Quán – Quả) — looking outward · looking inward · regulating).
2. Bolting on another indicator before you've finished using the one you already have
A Q&A: a student wanted to add Bollinger Bands because the three lines looked like support–resistance, breaking the middle line meant running to the other band, and it seemed to match wave-progression theory. The teacher's answer has two layers.
The timing layer. Get truly fluent with the system you're already learning first — roughly 6 months, once you're confident — then combine something new, and combine it in a spirit of exploration, not in the mindset of "I have to master this new thing right away."
The deeper layer, which matters more. Bollinger is really just another form of moving average / support–resistance. And support–resistance shows up best on price itself. Adding another line to the chart doesn't add information — it adds psychological noise: a range breaks out hard, price shoots outside the upper band → this creates a feeling of "too high already" → closing early on a wave that's actually still running correctly. What looks like "matching RSI's 70/30" is often just coinciding with an S–R zone you could already read off the price.
The most memorable illustrative case: a student said they couldn't draw support–resistance because their laptop screen was too small, so they relied on Bollinger instead for convenience. The teacher didn't forbid it, but pointed out that this was reaching for a substitute tool for something you haven't done enough of — the actual work needed is to keep drawing until it's clear. The comparison the teacher uses: getting tired of running, so you switch to a different sport.
One technical point that comes with this, easy to misread
On upward momentum: if RSI fails to make a peak ≥80 but price still breaks its previous high, momentum still counts as completed on the RSI. In other words, you measure by RSI, not by "price breaking a high means it hasn't reset." This is exactly the kind of misreading this note is about: remembering the right words but attaching them to the wrong marker.
