Core idea

This craft has four pieces: knowledge – thinking – tactics – psychology. By the end of the course the knowledge piece is complete, but pure knowledge only answers "is this right or wrong in theory" — it doesn't answer "so what do I do now" — and that gap is exactly what the other three pieces have to fill. Ask about each piece separately and everyone can answer; let one wave run and knowledge, thinking, and psychology all evaporate — that is precisely the gap between knowing and being able to use it.

Details

1. A real case: knowledge says NO, tactics say YES

Context: H1 has just formed a rolling-up pattern, but on H4 the RSI is still below both moving averages.

  • On knowledge alone: H1 is out of phase with H4 → 50/50 → you're fully entitled to skip this wave and not participate. This is the theoretically correct answer.
  • Adding tactics: H1 is the only data point on the board showing an accumulation of buying pressure. So watch the lower timeframes (the 45m has just turned up): if the lower timeframe can't get faked out and H1 turns back down, meaning selling pressure isn't showing up anymore → go long, betting that H1 + 45m can pull H4/H12 up.

Check the reverse case to see when you must NOT do this: if H12 has just turned down — meaning there's still plenty of "fuel" left for its downward move — then the board tilts firmly bearish, and there's no betting against that.

Bottom line: knowledge filters out what's 50/50; tactics decide which of those 50/50 cases is worth betting on, and under what risk-management conditions.

2. The tool that connects knowledge to action: THE TABLE

Draw two columns — factors favoring up / factors favoring down — and write them out (see Tactical mindset — the process to determine before entering a trade for the detailed method). Added from session 30:

  • The THIRD order state. It isn't just long and short. When the two columns are 50/50, SITTING STILL is also an order state — and the correct one. Most people who lose don't lose from picking the wrong side between long and short; they lose because they picked one of the two when they should have picked "sit still."
  • Don't be rigid about the number of bullet points. Five bullets on one side, seven on the other still counts as roughly equal. Only call it clear when one side is decisively dominant.
  • The real ratio: trades that are decisively one-sided (80/20) make up only about 20% of the market, maybe less. During a sideways stretch, 50/50 trades are nearly everything — drawing the table and getting 50/50 every time is normal, not a sign your knowledge is wrong. Not understanding this rule breeds inner conflict and reckless entries.
  • The table is also used when CLOSING a trade. Holding a short and wondering whether to close it → draw the table again. If it's still 50/50, the conclusion is "not enough evidence to close yet," which buys you time for the market to tip to one side instead of closing in a state of guessing tops and bottoms.
  • The table's main use isn't making money — it's AVOIDING RISK — and it matters equally whether the market is sideways or trending.

3. Matching psychology – action – timeframe correctly

This is where correct knowledge can still blow up your account:

  • Whatever timeframe you enter on, read the timeframe below it. Enter on H1 and you don't need to watch the 1m. Enter on m15 and you must watch the 1m/3m/5m.
  • The stop must match the timeframe you entered on. Don't place the stop at some past support/resistance zone that has nothing to do with the current wave. An old zone only becomes usable after price returns to retest and confirms it's still valid.
  • The action must match the psychology. Enter on a small timeframe with a tight stop ⇒ you must sit and watch the screen; if you want to go to sleep, pull the stop back to a wider zone. Entering on a small timeframe, setting a tight stop, then turning off the computer and going to sleep — getting stopped out is only natural.
  • Bargain for safety, not for profit. When the stop is placed tight on a very small timeframe, the teacher only enters half size. That's the difference between the teacher and a student: a student bargains for more profit, the teacher bargains for more safety.
  • A stop-loss is insurance, not lost money. Same logic as buying life insurance: it's something that protects you, not money thrown away.

4. Why "knowing" never turns into "being able to use it"

The mechanism the teacher explains (borrowing the body – mind – wisdom framework):

  • Mind and wisdom don't rise on their own. Sit still staring at the screen and you won't wake up smarter tomorrow, won't wake up profitable. No reading, no asking, no drilling means intelligence stays put; and the mind (the reach of your goal, the size of your ambition) also stays put at its current level.
  • The BODY is the only thing you can actively control. Force the body into discipline, force it to drill, force it to keep records → in that process, mind and wisdom get pulled up along with it. In parallel there's the triad of morals – concentration – wisdom: keeping to your rules = forcing yourself into principles and discipline; concentration arises from morals; wisdom arises from concentration.
  • The teacher says it plainly: you only touch about 10% of your true ability once you've drilled to the point of tears. (This number is the teacher's way of emphasizing the point, not a statistic.)

5. Reversing the CAUSE – EFFECT relationship

This is the most valuable line of the session:

Correct analysis, correct decisions, correct results — those are the EFFECT, not the CAUSE.

The cause is: discipline, reading, drilling, keeping records, reviewing your trades. Skip the cause and demand the effect, and the analysis will be wrong, the decisions will be wrong, and the result will naturally be wrong. If you're stuck wondering "why do I keep analyzing and still get it wrong," the problem is in the cause, not in the analysis step.

6. Psychology getting swept along by the market's rhythm

The paradox the teacher points out: when the market is sideways with no real data, students throw themselves into intense analysis; when a real wave actually runs, they stop analyzing and let the wave sweep them along. Because when price moves fast, pressure – FOMO – fear – tension pile up, and almost no one can stay in control of themselves. There's only one cure: train yourself to slow down and observe.

7. Learning from your own trades

  • Learning from the teacher is only the starting phase. The main phase afterward is self-teaching from your own trades — both the wrong ones and the right ones.
  • This craft is, more than anything, a craft of learning about yourself: separating me from my emotions, so you know what your emotions would make you do if left unchecked.
  • The rational mind accepts "each trade is an independent entity," "the stop-loss is non-negotiable" — but whether your deep inner emotions accept it is the hard part. The only way: repeat it enough times that it becomes instinctive thinking.
  • Rewatch the lecture video no fewer than 3 times — see bon vong tron tien bo.

8. Plenty of knowledge plus OVERCONFIDENCE kills you even faster

A case the teacher tells: someone working in finance, holding a very high-level CFA, still got wiped out trading. The fault wasn't the knowledge — it was being too confident in one's own knowledge/credentials → which breeds an overconfident mindset. Overconfidence is exactly the word "conceit" in greed–anger–delusion–conceit–doubt (see Psychology lessons from students of the previous cohort): expectations set too high, unwilling to accept correction, unwilling to accept the market moving against you.

The root rule: in financial markets there is only one thing that is always right — the market; an investor is never entitled to always be right. Your job is to follow the market / focus on the trend, not to force the market to follow you.

This is the flip side of High-probability patterns and point 5 above: someone who lacks knowledge trades recklessly, but someone with plenty of knowledge and no self-control dies of arrogance — the same root cause, "behaving like a gambler" (tu duy trader vs tu duy con bac).

Putting it into practice

  1. Before every trade: draw the two-column table. If it's roughly even → choose the third order state (sit still), log in your journal that you chose to sit still (so you can count it at month's end).
  2. If you still want to bet within the 50/50 zone: write down clearly what exactly you're betting on (e.g. "H1+45m can pull H4 up") and what signal would prove the bet wrong → that is precisely your exit condition.
  3. Write it down on paper: the timeframe I'm entering on = ___ ⇒ the timeframe I'm watching = ___ ⇒ the stop follows the structure of ___ ⇒ can I actually sit and watch the screen? If you can't watch it, pull the stop back and lower your expectations, or don't enter.
  4. At month's end, evaluate two separate aspects: (a) your training process, (b) your practice with the actual account — which trades won because you entered correctly, which won by luck, which got stopped out because of emotion.

What the teacher stresses / common traps

  • "You can't want to fight like a tiger while training like a pig." A line the teacher quotes to stress that this field has a very high dropout rate — even someone already successful in another field can die here just as easily from a lack of self-control.
  • In any given second or minute, an investor can turn into a gambler. See tu duy trader vs tu duy con bac.
  • The trap of asking the same learned knowledge again 3–4 times: if the teacher has already demonstrated the same type of trade 3–4 times and you still have to ask, the problem is in how you're reviewing, not in the knowledge itself.
  • In this system, Fibonacci is used to measure a wave's strength, not to close trades — see Wave validity — the equation a + b = c.
  • The trap of rigid thinking: a student asks "does the lower timeframe have to be exactly 3–7 times smaller, teacher?" → the teacher answers it's only approximate; just open the lower timeframes one by one below the one you trade and see which timeframe the wave is actually running on. Understanding knowledge to the point of rigidity is also a way of understanding it wrong.
