TRKD:How to detect when stock symbol have changed

Do you have a resolution to

  1. How to know when stocks have changed symbol from NASDAQ:A to NASDAQ:B
  2. How to know when stocks have changed exchange from NASDAQ:A to NYSE:A?

  3. What is `Company ID Type` to reference fundamental and financial data even stock has changed exchange or symbol? there're RIC, ISIN, REPNO and more. I'm using RIC to reference NASDAQ:A as A.O to get all stock information every day. But when NASDAQ:A has changed to NASDAQ:B, RIC=A.O isn't working and won't change data to new exchange or symbol. So I have duplicated stocks in my product, both NASDAQ:A and NASDAQ:B.

1) & 2) You need to check the changes page in order to find if there is a symbol change. US/CHANGES1 page will provide you a list of US stock exchange information and in specific for NYSE it will be NYS/CHANGE2. Foe entire universe you can refer to WORLD/CHANGE1.

3) You can search financial statements for a company using RIC or REPONO. On TRKD API search you can use search service i.e., ISSUEISIN to RIC & REPONO with primary RIC fitler as an addition.

Also there is no NASDAQ A or B. We have exchange code .OQ for NASDAQ specific exchange code or .O which is NASDAQ consolidated RIC which gets values from different regional exchanges of US
