Hi, I am looking for some stock symbol look-up API. I could able to query yahoo finance with a symbol & could able to retrieve the stock price & other details.
I am looking for some auto-complete stock look-up API like if i query fo "Go*" ... how can i get all stock symbols starting with GO* = Goog etc ... is there any APi for wildcard stock symbol searches
Any help would be great ..
Thanks
Any autocomplete API or toolkit should work if you put the tickers in as a source. You will probably have to host it yourself as I don't know of any public ones.
There's a simple problem here and a more complex problem.
If your list of symbols is static, then you could use any typical autocomplete API against a file that you maintain locally.
However, the list of symbols is rarely static. Symbols are constantly being added or erased and changed due to a variety of financial market situations (IPO, acquisitions, mergers, renames, bankrupcies, etc.). Many symbols are also traded on specific exchanges, and some symbols are cross listed. There are also financial instruments that are not simply stocks, such as indices, commodities, etc. The general term for this is "instruments definitions" and a complete list of such definitions is a service provided by companies such as Reuters or Bloomberg.
I am not familiar with any free and open instrument lists that you could get for free, and you need to make sure that you are complying with the licenses of services that allow you to get a current list.
If you can tolerate a delay of one business day, you might be able to scrape the list from a variety of sources that provide close-of-business listings for all stocks in the US. The WSJ has a printed list (likely also an electronic one). Eoddata provides such a list, etc. But make sure that you are complying with their terms.
You can try using the "Company Search" operation in the Company Fundamentals API here: http://www.mergent.com/servius/
