In your opinion, what is the most reliable way to tell if a market is bullish or bearish?

Friends, today I wanted to talk to you about the indicators that truly capture the pulse of the crypto market. Is the market bullish or bearish? I believe I get a clearer picture not only by looking at charts but also by studying the indicators that drive market dynamics.

Fundamental metrics, especially those related to US markets (S&P 500, Nasdaq), Bitcoin, and stablecoin dominance, always guide me.
