Core idea
In this session the teacher invited students from a previous cohort up to retell the exact spots where they'd stumbled. The common thread in every story: the technical system isn't what cost them money — their psychological state was, and the stronger the system, the more easily it breeds arrogance. The biggest operating lesson to take away: measure everything in %, not in money; work independently; and trace every mistake back to the psychological state that produced it, instead of just fixing the symptom.
(The stories below are retold anonymously, distilled into behavior patterns.)
Details — typical failure-psychology patterns
1. "Muscle memory" — carrying a previous phase's tactics into a new phase
- Context: many months of sideways market, used to trading both directions back to back (long → close → short → close).
- Mechanism: the market is very good at "training" a trader's psychology — a pattern repeated long enough gets nailed into your reflexes.
- Consequence: when the market shifts into a 1D uptrend, you still short out of the old reflex, i.e. trade against the higher timeframe.
- Fix: "consistent knowledge, flexible tactics." During a 1D uptrend, only buy and wait to buy; during a downtrend, only short and wait to short. Every time the market changes shape, you have to actively change your tactical mindset. See sideways vs. trend strategy.
2. Expecting the wrong timeframe → overholding or closing too early
- Context: entering on an M5/M15 signal but mentally expecting an H1-sized target → "restless, not knowing where it's going to stop, not knowing how to manage the trade."
- Two ways to die from this: (a) price returns to the lower-timeframe support and bounces without you closing → it turns into a stop-loss; (b) getting scared and closing too early, then being stunned when price keeps going, and then re-entering at a worse price.
- Fix (a hard rule): a wave on a given timeframe should only be expected to reach that timeframe's nearest resistance/support. Identify the right timeframe correctly → the right SL and the right TP follow automatically. See staying consistent on timeframe.
3. Ego tied to a publicly stated call
- Mechanism: once you've shared a call in the group/on social media, your ego gets attached to it; if the call is wrong, you won't accept you're wrong.
- Consequence: stubbornness, clinging to the scenario, trading against the real market. The people listening get hurt too — they lose their own independent thinking.
- Fix: build a scenario but don't cling to it; if the market breaks the scenario, follow the market immediately, and have the opposite-direction trade ready to go at the same time. The ultimate goal is profit, not being right in your analysis.
- Note that with the same scenario, each person has a different risk tolerance and size → the same trade produces two opposite psychological states; the other person has already closed, you haven't, price comes back → you get frustrated.
4. Overconfidence after a winning streak
- Context: seeing the system deliver high-probability entries → breeds complacency → trading every little wave carelessly, raising leverage.
- Consequence: the account goes down almost 10%.
- Fix: slow down, gradually work back to break-even, let belief return. Lesson: the stronger the system, the more easily it breeds arrogance — discipline is what protects the account.
5. The escalating chain: delusion → aversion → craving
- One session had a beautiful trade → you feel like you're good (delusion/conceit) → you see someone else doing even better and wonder "why can't I catch a move like that" (aversion/resentment) → you jump into a small timeframe to trade because "I know what I'm doing" (craving/ignorance) → you lose → you interrogate yourself, a "terrible internal struggle."
- Fix: trace that mistake back to which psychological state it came from, and treat the root, not the symptom.
6. Comparing yourself to others → resentment → all-in
- Mechanism: everyone enters the market from a different position (capital, financial burdens, family). Seeing someone else's results → comparing → resentment → losing discipline → all-in once, twice → blowing the account.
- Fix: minimize, as much as possible, knowing how much someone else made or which trade they won. Don't pay attention to it.
7. Doubting the system
- Context: someone from a profession that demands absolute precision (e.g. a programmer) comes into trading.
- Mechanism: the market runs on probability, usually only about 50% of the signs line up, never a full 100% of signals. You enter with enough confirming signs and it still goes against you → it breeds doubt about your knowledge, doubt about the system.
- Consequence: not daring to enter even on a beautiful setup, or trading erratically.
- Fix: accept the probabilistic nature of the job.
8. Fear of losing profit (different from fear of losing money)
- One person diagnosed himself very precisely: "I'm not afraid of getting stopped out, but I'm very afraid of losing profit" — the root is greed for money in order to buy freedom.
- Consequence: closing too early over and over, never capturing a full wave.
The "greed – aversion – craving – conceit – doubt" framework and how to use it
Core idea (coined by a student, endorsed by the teacher): a strength in your old profession usually becomes a weakness in trading, and vice versa — "coming into trading is like looking in a mirror that flips everything."
- Someone with a high academic degree/financial certification → conceit (arrogance about their knowledge) is the ringleader → they lose → it breeds aversion toward the market. Fixing "aversion" is fixing the wrong thing; you have to fix "conceit."
- A programmer (who demands absolute precision) → doubt is the ringleader.
- Someone who's not very attuned to what other people think (a weakness back at their old job) → becomes a strength in trading: someone else winning or losing doesn't affect them.
How to use it:
- Among the five culprits there's always one ringleader; the other four are just consequences. Find and eliminate the ringleader and the other four cancel themselves out.
- To find it: analyze your own strengths/weaknesses in real life, at your old job.
- You have to get specific, not generic: is the greed greed for money or greed for knowledge? Is the aversion aversion toward the market or aversion toward a peer who's better than you? Is the craving craving for the market to the point where you have no other activity left in your life?
- The "do the opposite" method: whatever you're afraid of, go do exactly that, until the fear is gone. Afraid of getting stopped out → let it hit stop. Afraid of closing too early → close early on purpose. Do it until it feels light — that's when you've gotten past it.
The pen–paper–candle exercise (the tool rated most powerful)
- Midnight, a dark room, one candle, no electronic devices, no flickering lights.
- A pencil (writes fast, no fear of mistakes, keeps up with the flow of your thoughts) + a sheet of paper.
- Write a guiding question and then answer it, for example: "Am I good yet?" → "Why am I not good yet?" → write out everything, hide nothing.
- A variant one student added on their own: every time you stumble, first write out a professional trader's whole mindset, then ask, "why did I let emotion override reason when the scenario was already laid out?"
- The teacher says this is essentially meditation broken down into step-by-step stages: real meditation takes 5–10 years before you can observe an emotion the moment it arises, but this exercise anyone can do right away.
- A warning in advance: "crying while you write is normal, even for men."
Operating rules distilled from this
- Measure in %, not in money. Looking at "$20,000 ≈ nearly 500 million VND" while earning a salary of 10–20 million VND/month is a guaranteed way to close too early. Set goals in percentage terms.
- Only exit on a reversal signal, never exit because of a feeling.
- Stay one beat slower than the market.
- Prefer a prop (funded) account over your own money — when the money isn't yours, $50,000, $100,000 is "just a number," which cuts the emotional impact.
- Separate the phases: while you're still refining your knowledge, switch to demo, don't trade real money — because "greed for knowledge" compounding with "greed for money" creates too much pressure. "I can't do both things at once."
- Work independently: don't ask each other for signals, don't hand each other scenarios to trade off of.
- When entering on a higher-timeframe wave, average into it across the zones you've already marked out — and it has to be averaging IN THE RIGHT DIRECTION (price getting progressively better), not averaging against the trend. "Averaging against the trend is death."
- The "price line = train" mindset: reaching support doesn't force you to close right away; let the train's acceleration slow down until it fully stops, and only close once you see it curling up on the lower timeframe.
- A very tight SL + a very wide TP are two sides of the same thing — minimize risk to the max and profit rises on its own; a short SL lets you enter a bigger size for the same amount of risk. "The two are like communicating vessels."
- Ration your tools. The group tends to dig too deep or use too many extra indicators outside the system → sees signals everywhere → enters too early.
Timeframes & realistic expectations (as stated by the teacher in this session)
- 2–3 months to round out your knowledge; 6 months to 1 year to master the skill set.
- The fourth skill — psychology — needs "10 years, 25 years, 35 years, you still have to keep practicing it."
- The teacher only contributes 10–20% of the result; 80–90% is individual effort.
- One student self-assessed that psychology accounts for ~60% of trading results.
- Reference results from the previous cohort: passing a $300,000 prop account, income of ~$20,000/month; some people scaled up gradually from $50,000 → $100,000 → $300,000. (These are reference points for a few individuals, not an average.)
- A prolonged sideways phase is when psychology gets worn down the most: the market "tortures" you with a loop of hope and disappointment until the trader runs out of patience and quits, and only then does the market move. Some people lost sleep for many nights, tested a prop account up to 4 times before passing.
How the five afflictions show up on A SPECIFIC TRADE
The greed–aversion–craving–conceit–doubt framework above is a diagnostic map; session 22 translates it into how it actually shows up in your order actions, which is much easier to self-check. Everyone has all five, just in different proportions:
| Affliction | How it shows up on a trade |
|---|---|
| Greed | Wanting the wave to run its absolute full course; demanding too tight an SL for a higher-timeframe wave; jumping into a zone with no wave at all just to "find some data" |
| Aversion | Getting stopped out / repeated disappointment → taking revenge on the market, breaking discipline, blowing the account |
| Craving | Addicted to entering trades — no patience to wait for a wave, not waiting for the trend to finish, not waiting for a sign of weakness before closing |
| Conceit | A winning streak → overconfidence, stubbornly holding the scenario, not accepting you're wrong. The counterweight: the market is always right; the trader just follows along to pick up profit |
| Doubt | Knowledge not yet sufficient → either gambling, or not daring to enter; or haunted by an old stop-loss so even a clear signal still feels scary |
The typical destructive chain in this session: regretting a noisy peak you didn't manage to close at (even though the parent timeframe hasn't changed character) → it breeds an internal conflict → you flip into shorting recklessly. This is exactly the explanation for the phenomenon of "the analysis is fine but the account goes sideways": you catch a beautiful wave and then torch it right back in a zone with no data.
A hard rule to block all five afflictions at once: if it's clear, play; if it's not clear, skip it — even a thousand-point wave with no data behind it, still turn your back on it. The reasoning is simple: a real wave that's big enough will have data behind it; a wave with no data that happens to be big is just luck.
A warning about regret: letting regret drive your actions sets a bad precedent. A few individual trades might do better than staying consistent, but across the whole process that's a probability imbalance. The teacher is blunt about the survival rate: "out of 100 guys, maybe one succeeds, not 5%" — the first filter is people with no knowledge (~80–90%); the second filter is people who have the knowledge but can't hold onto their mind.
Putting it into practice
- Write out your own five culprits (greed/aversion/craving/conceit/doubt), one specific line for each, then circle the ringleader. Start from the question: "What's my biggest strength from my old profession? What weakness does it become in trading?"
- Convert your entire set of goals and reports to %. Hide the absolute cash balance if you need to.
- Cut off your sources of comparison: turn off group notifications that show off trades, don't ask who's making how much.
- If you're still in the learning phase → switch to demo until the system runs steadily.
- Do the pen–paper–candle exercise after every stumble, not on a schedule — stumbling is what triggers it.
- Before posting any call to the group/social media, ask yourself: "why am I posting this — to be right, or to profit?"
What the teacher stresses / common traps
- "Whatever you're afraid of today, go do exactly that thing." (verbatim)
- "Nothing is as brutal a struggle as struggling with yourself." (verbatim)
- "The more each of you stands alone, the better off each of you is." (verbatim)
- "You might be able to fool someone else, but you can never fool yourself." (verbatim)
- "Just stay one beat slower than the market and you win." (verbatim)
- The biggest trap in this session: it sounds great when you hear it, but you can't trace your own mistake back to which psychological state caused it → so you fix the symptom instead (cutting losses sooner, setting a tighter SL) while the root stays intact → it repeats a few weeks later.
- A second trap: fixing the wrong culprit. Losing because of conceit, but going and fixing a bout of aversion toward the market instead.
