When a company is acquired, goes bankrupt, or is otherwise removed from an exchange, its ticker stops trading \u2014 but its price history, fundamentals, dividends and splits stay in EODHD. You can list every delisted symbol on an exchange and then query it with the same endpoints you use for active tickers. This is what makes survivorship-bias-free backtesting and long-horizon research possible.<\/p>\n\n\n\n

Working with delisted data is a two-step job: find the ticker in the exchange symbol list, then query the regular data endpoints with it. The traps are all in step one \u2014 the ticker you remember may now belong to a different company.<\/p>\n\n\n

Scope at a glance. Delisted symbols are listed per exchange with the delisted=1 flag, and every exchange we cover has them \u2014 60,191 on US alone, 9,587 on Frankfurt, 4,077 on the LSE (September 2026). Once you have a code, the End-of-Day, Fundamentals, Dividends, Splits and Intraday endpoints behave exactly as they do for active tickers. Listing the symbols costs 1 API call.<\/p>\n\n<\/div>\n <\/div>\n \n\n\n\n\n\n

Step 1 \u2014 List Delisted Tickers<\/h2>\n\n\n\n

Use the Exchange Symbol List endpoint with delisted=1. It returns only the inactive symbols for that exchange; without the flag, or with delisted=0, you get only the active ones. The exchange code goes in the path \u2014 US covers the combined US exchanges.<\/p>\n\n\n
