Price Milestone Crossings

Each dot marks a day when price crossed a round-number milestone ($1k, $10k, $20k, …) in either direction. Clusters of dots at one level show price churning around that milestone; a level with a single dot was crossed once and never revisited.

Round numbers act as psychological support and resistance, and this chart makes the battlegrounds visible — the $10k and $20k levels were each crossed dozens of times before finally being left behind, while levels conquered in strong trends barely register a second dot.
