Trading Insights

1. The essence and mindset of trading
   ① Don’t let trading occupy your entire life; family and work are more important than short-term gains and losses.
   ② The core difference between veterans and novices: not getting euphoric from profits and not panicking from losses.
   ③ Funds must be idle; "pressure funds" for buying a house or getting married should never enter the market, or else the mindset will collapse.
   ④ The amount of capital affects mindset: losing $10,000 from $100,000 feels vastly different than losing $10,000 from $20,000; one must be able to withstand volatility and avoid frequent trading.

2. Core principles of trading
   ① Controlling position size is the top priority; each market entry should not exceed 30% of total capital. For example, with a $10,000 principal, a single operation should not exceed $3,000. After making profits, one can gradually increase the position, but the total position must still be restrained.
   ② Stop-loss must be set; not setting a stop-loss is equivalent to gambling with your life; one mistake could wipe out everything.

3. Simple and practical Bollinger Bands strategy
   1) Core components: Middle band (20-day moving average, indicating trend), upper band (resistance), lower band (support); 95% of prices fluctuate within the channel.
   2) Three basic strategies
   ① Trend market: When the middle band is rising, buy when the price retraces to the middle band, setting the stop-loss below the lower band.
   ② Range market: Buy when the price drops to the lower band (better with oversold signals), sell when it rebounds to the middle or upper band.
   ③ Extreme market: Reduce positions when the price breaks above the upper band (overbought), do not buy when it drops below the lower band to avoid being trapped by chasing highs.
   3) Three major taboos
   ① When the middle band is declining (downtrend), do not buy at the lower band.
   ② When the price breaks the band, check the trading volume; if there is no increase in volume, it may be a false breakout.
   ③ Do not rely solely on Bollinger Bands; combine with indicators like MACD and RSI.

4. Summary
   The key to trading: control position size, set stop-losses, maintain a stable mindset, and use simple strategies (like Bollinger Bands) to respond to market conditions; do not let greed and fear dictate decisions. Remember, preserving capital is always more important than short-term windfall profits.
