General RSI Guidelines:

• Trend Confirmation: During an uptrend, RSI often stays above 30 and frequently reaches 70. During a downtrend, it often stays below 70 and frequently reaches 30.
• Divergence: Watch for divergences where price makes a new high/low, but RSI does not. This can signal a weakening trend.
• Centerline Crossover: A move above 50 (from below) can suggest an upward trend, while a move below 50 (from above) can suggest a downward trend.
• False Signals: In strong trends, RSI can remain in overbought/oversold territory for extended periods. Always use RSI in conjunction with other indicators and price action analysis.
