How this works

Each 5-minute Polymarket market resolves UP or DOWN. We aggregate outcomes by their start time and weekday, then compute the UP rate and a statistical significance score (Z-score). Patterns with more occurrences and higher Z-scores are more reliable. Past patterns do not guarantee future results.
