The experienced teacher's explanation is very comprehensive, summarized as follows:

Building a trading system and risk management:

· Trading is counterintuitive, but correct trading can accelerate personal growth;

· Common issues for beginners: large emotional fluctuations, difficulty executing stop-losses, need to establish a trading system;

· Capital allocation advice: low-risk investments (quantitative funds/wealth management) + idle money trading (spot/contract);

· Account isolation strategy: long-term accounts ≤ 3x leverage, short-term accounts about 10x leverage, to avoid fund misappropriation; -

Position and leverage management:

· Use leverage as a tool: 3x leverage with 3% stop-loss can enforce discipline;

· Position management methods: pyramid/inverted pyramid/rectangle/Kelly formula/martingale strategy;

· Gradual opening of positions and taking profits can improve the fault tolerance rate to 6%;

Application of technical indicators:

· Indicators need to understand the principles (e.g., MA smooths based on closing prices), be wary of lag;

· Recommended indicators: 144/169 moving averages (Vegas channel), MACD, Bollinger Bands;

· Multi-indicator cross-validation increases win rates;

Support/resistance level judgment:

· Judgment methods: Fibonacci/Dow Theory/integer levels/liquidity heat map;

· Key point: effectiveness of volume concentration areas > pure technical patterns;

Trading mindset and system establishment:

· System elements: clear opening logic, profit-loss ratio calculation, strict profit-taking and stop-loss;

· Training path: simulated trading → small position real trading → review and optimize → normal position;

· Emotional management: accept losses as part of the plan;

Utilization of idle time:

· Review historical trades, learn new strategies such as options/arbitrage;

· Set price alerts to capture key levels;
