Symbol Change History API<\/h2>\n\n\n\n

When a publicly traded company changes its ticker symbol \u2014 due to a rebrand, merger, SPAC transaction, or corporate restructuring \u2014 the old symbol stops working and a new one takes its place. The Symbol Change History API tracks these changes so you can keep your portfolios, watchlists, and historical data in sync.<\/p>\n\n\n\n\n
