Recognizing when to stop playing for the day involves paying attention to both emotional and financial cues. If you're feeling frustrated, anxious, or overly excited, it may be a sign that your judgment is compromised, making it wise to take a break. Additionally, if you find yourself chasing losses or betting more than intended, it's a strong indicator that you should step away. Monitoring your bankroll is also essential; if you're nearing your loss limit or have exhausted your budget for the session, it's time to pack up.
