Multi-Period Resonance Indicator Core Logic

Multi-period resonance is a classic strategy for ultra-short-term trading. The core logic is:
1. Set the direction on a higher timeframe: Use 1H/4H and other higher timeframes to determine the main market trend, avoiding trades against the major trend.
2. Find entry points on lower timeframes: Use 5M/15M and other lower timeframes to identify precise entry points, improving the risk-reward ratio.
3. Resonance to increase win rate: Only when the trend on both higher and lower timeframes is aligned is there a high-confidence entry signal; in divergence, caution is advised, and observing or trading lightly for trial is recommended. #ETH
