Here's a summary of what I learned today: there might be some issues with the organization, so I'll review it again tomorrow to study further. This is only for my own learning, and it may not be accurate. I need to observe the market more and verify it through practical operations with 1x capital.

1. Drawing support and resistance lines, Fibonacci lines allows for a clearer view of support and resistance levels, which helps to determine where to set stop-loss and take-profit points, or to take profits in batches.
2. If the first candlestick is a large bearish candle and the second candlestick is a bullish candle that closes without retracing to half of the first candlestick, it is highly likely that the price will continue to move down. If the second bullish candle closes above half of the first candlestick, it is highly likely that the trend will reverse upwards. The same applies in the opposite direction. If at the close of the second candlestick, it breaks through a resistance or support level and stays above the resistance line or below the support level, the same principle applies.
3. Analyze the BTC market by first looking at the larger time frames: weekly, daily, 12-hour, 8-hour, and so on, down to 1 minute. Then also examine 1 minute, 3 minutes, 5 minutes, 1 hour... and other time frames. By looking from large to small and from small to large, when the overall trend is consistent, the trend of this market can be considered established.
4. Top reversal and bottom reversal patterns: the first candle is a bearish candle, the second candle is a small bullish candle, and the third candle is a bullish candle that completely engulfs the first one. That is a bottom reversal pattern, indicating a bearish trend to... resistance level? Well, just look for a short distance to short, and we'll see tomorrow if it's accurate.
