2/5 The problem is in the picture
I can only share with you my personal approach
1. Confirm the trend first, short the downward trend, and go long the upward trend.
2. I personally prefer to do a rebound/resistance rebound (combine the indicators and the support and resistance on the market for reference)
Summary: Confirm the trend first, find support/resistance in the main chart, and enter the market based on the overbought and oversold indicators and whether MACD gives a continuation signal.
Stop loss is sometimes set at the previous resistance zone, which means it will be a wider stop loss. To stop profit, look for potential support below.
