Key performance timeline (claims from speaker)

Started with 5 million KRW seed capital; grew to a personal account > 4.5 billion KRW.
Contest: 100M KRW → 300M KRW in one month (≈369% return).
Claimed it took ~6 months to make 100M KRW from 5M KRW.
2020: benefited from COVID‑19 market; ~60M KRW/month; March 2021 >100M KRW.
Sep–Oct 2023: nearly 280M KRW; some months >300M KRW.
2024: reduced trading due to weak market.
2025: reported monthly profits exceeding 500M KRW in a month; daily profit >100M KRW (Oct 2025). One 2025 account showed a 1.6 billion KRW profit (per transcript).
He also described long drawdowns (e.g., continuous losses Jan–Jul 2019 before recovery).

Behavioral / career guidance

Secure living expenses before quitting salaried work (advice cited: 1–2 years’ worth). Shin said he had >300M KRW before going full‑time.
Survive slumps: reduce position sizing during drawdowns; start small to build winning habits.
Mentor advice: earn steadily for several years, avoid FOMO, protect capital (grow slowly and protect what you have).
Develop “holding power”: practice letting winners run and cutting losers quickly.

Core principles (maxims)

“Buy low” — buy when others panic/sell; buy on sell‑offs rather than chasing breakouts. “Chasing is death” — avoid buying after a breakout you’re chasing. “Hold profits long, take losses short” — develop holding power and discipline.

Other repeated rules:

Scale into positions (buy in installments).
Use predefined sell rules (don’t sell just because you’re satisfied).
Distinguish bull vs bear market: swing techniques work better in bulls; be conservative in bears.

Methodologies — rules & checklists

1) Closing‑price trading (마감가 베팅) — checklist

Stock selection:

Has an “ingredient”/catalyst (fundamental or sector justification).
Noticeably large trading amount/volume vs recent days.
Chart near previous high or attempting a new high (thin supply zone).
Prefer a short upper wick (single short candle).
Adequate adjustment/consolidation time after breakout (~1 week to ~2 months).
Avoid if price is firmly below the 5‑day moving average.
For large caps, foreign & institutional buying is a positive signal.

Execution:

Confirm upward trend on minute chart.
Buy near market close (he described starting 30 minutes before close; explicitly cited 15:00 / 3:00 PM).
If bought after ~14:00–15:00 and intraday closing profit is 2–3%, realize at least some profit or exit early the next morning.

2) Swing trading — checklist

Prefer large caps or stocks you can add to on dips.
Buy during sell‑offs (bearish candles) when you judge the trend remains intact; scale in small first and add after confirmation.
For large caps: buy near a low that holds (downside rigidity); use moving averages (20‑day used as a sell cue in examples).
For small/medium theme stocks: may buy when a clear low is broken if catalysts/schedules remain and market makers haven’t left.
Hold through volatility while the trend is alive; don’t sell until trend signs (e.g., 5‑day/10‑day MA or previous day’s low) break.

3) Position sizing & exits

Start small when uncertain; scale in on confidence.
Sell in installments according to rules (time‑of‑day, technical break like MA break, or chart pattern such as a “right shoulder”).
Intraday/closing bets: take partial profits at 2–3% intraday; avoid further intraday trading if significant profit was already made early.
Use stop‑loss discipline, but recognize large‑cap names may absorb slight breaches below obvious support — he sometimes accumulates into panic sells.

4) Risk management & psychology

Reduce exposure during slumps; adopt a survival‑first mindset.
Prepare 1–2 years’ living expenses before going full‑time.
Resist FOMO; follow mentor advice to grow steadily.
Build holding power through practice: let winners run, cut losers fast.

Technical cues & metrics referenced

Moving averages used as references: 5‑day, 10‑day, 20‑day, 60‑line, 120‑line. (Example: 20‑day MA as a sell threshold; 5‑day breach = caution.)
Buy signals: bullish candle with increased volume after consolidation; single short candle with short upper wick; minute‑chart confirmation.
Sell signals: break below specified MA or yesterday’s low, certain time rules, or minute‑chart pattern break.
Volume: look for spikes vs recent days. (Example: Hanmi — first bullish candle ~700 million volume; subsequent long bullish candle cited as 2.5 trillion KRW trading volume — units unclear in transcript.)
Profit targets: closing trades — partial realization at 2–3% intraday; swing trades — no fixed target, ride MA‑confirmed trends.

Concrete examples / illustrative calls

Hanmi Semiconductor: example chart — break toward historical high, then ~4 trading days correction; he waits for timeframe adjustment, draws the low point, buys on sell‑off for large‑cap (20‑day MA used as sell threshold). If volume increases and a strong bullish candle forms, he adds — mentor example cited a typical next‑day gain of ~8%.
SK Hynix: used to illustrate “buy on short single candle” after consolidation/failed breakout on a round number.
Index ETFs: buying index ETFs during market crashes presented as a simple buy‑low tactic.

Explicit recommendations & cautions

Do not chase breakouts (chasing = “death”).
Buy during panic/sell‑offs only after studying the stock and confirming trend intact.
Use smaller positions and scale up after confirmation.
In closing trades, realize partial profits at 2–3% or sell next morning.
In swing trades during bull markets, holding power and tolerance for volatility are key; in bear markets be more cautious.
If closing price fails to recover and trend turns down, cut losses quickly.
Combine chart analysis with fundamentals/catalysts and volume — don’t rely solely on patterns.

Performance disclosure & context

The speaker disclosed historical monthly and daily profits but emphasized nonlinearity: long periods of losses and drawdowns occurred. He stressed survival and consistency over singular large wins.

Short takeaway

Two primary playbooks:

Closing‑price intraday bets — late‑day buys into thin supply near highs after consolidation with volume confirmation; short targets ~2–3% intraday.
Swing trading — buy sell‑offs in large caps with scale‑in and let winners run along moving averages.

Core edge: combine catalyst/fundamental “ingredients” with volume and supply/demand chart context; avoid chasing; protect capital during slumps; use disciplined scaling and exit rules.
