How to tell if it's bullish or bearish?

Hello there, can you please clarify for me how one can accurately determine if the market is currently in a bullish or bearish state? I've heard various indicators and strategies mentioned, but I'm still unsure of the most reliable way to gauge the overall sentiment and direction of the market. Could you provide some guidance on this, perhaps highlighting some key factors to consider and potential pitfalls to avoid? Thank you!
