Core Pillars and Themes

Three pillars: psychology, trading tactics, money management; record-keeping ties them together.
Quote: “The public wants gurus... No guru is going to make you rich.”

Risk and Money Management

Markets can destroy accounts via single large losses or many small losses.
Two rules protect capital: limit per-trade risk and pause after cumulative monthly drawdowns.
Practice defensive money management; guard capital like a scuba diver guards air.

Risk Management Rules and Example

Rule	Purpose	Definition	Example Parameters	Implication
2% Rule	Prevent “shark bite” large loss	Risk ≤ 2% of account per trade	Account £50,000 → risk £1,000 per trade	Set stop-loss to cap loss at £1,000
6% Rule	Prevent “piranha” cumulative loss	If monthly losses + open risk ≥ 6%, stop new trades for month	Threshold £3,000 on £50,000 account	Pause trading, reassess systems
Position Sizing Example	Align size with stop distance	Stop at £9 on £10 stock, £1 risk per share	Risk £1,000 → 1,000 shares → £10,000 position	Position ≈ 20% of account, risk still 2%

Record-Keeping and Discipline

Keep a trading diary: document entry/exit reasons; find patterns of success and failure.
Monitor personal equity curve to judge system efficiency and detect drawdowns early.
Without tracking gains/losses, improvement is impossible; treat like weight control.

Psychology: Individual and Crowd

Crowd membership increases credulity and impulsiveness; emotions track price swings.
Trend following can be powerful; think rationally while trading with the crowd.
Have a predefined strategy and plan; question whether crowd movement aligns with your criteria.

Chart and Technical Analysis Basics

Trade with eyes open: recognize real trends and turns; avoid regrets and wishful thinking.
Support arises from trader memory of prior lows; resistance from selling halting advances.
Trading is about probabilities; patterns provide guidance, not certainty.

Bar Chart Interpretation

Element	Indicates	Guidance
Open	Amateur opinion of value	Early moves reflect non-professional activity
Close	Professional opinion of value	Close > open suggests professional bullishness
High	Power of bulls	Rising highs show strengthening buyers
Low	Power of bears	Falling lows show strengthening sellers
Range	Volatility and conviction	Wider ranges can signal strong participation

Key Quotes and Takeaways

“Markets can snuff out an account with a single horrible loss... like a shark bite.”
“Every winner needs... psychology, a logical trading system, and good money management.”
