United States is the largest single market for floating chart apps at 27.2% — but no country dominates, meaning floating chart apps serve a globally distributed merchant base. Netherlands follows at 16.1%, with United Kingdom at 5.5%. Together, the top 3 markets account for 48.8% of floating chart app installs worldwide. Hong Kong (5.4%) and India (5.2%) round out the top 5. Netherlands is the fastest-growing market this month (+2.8pp), pointing to accelerating demand outside the established leaders.

With United States's 27.2% as the largest single market and the rest spread across many countries, the leading floating chart apps tend to be region-agnostic by design — geography matters less for app choice here than features, pricing, and support quality.
