wtf is allstocks?

AllStocks is a data repository rather than a piece of software. It contains a CSV file, a plain text spreadsheet format, that lists the symbol, exchange, exchange name, and Yahoo Finance ticker suffix for a large number of stocks traded on major exchanges around the world. The README explains that a usable Yahoo Finance ticker can be built by simply joining a stock's symbol with the suffix listed in the file. For example, the symbol INFY combined with the suffix .NS produces INFY.NS, the correct Yahoo Finance ticker for that stock on India's National Stock Exchange. This means the file works as a lookup table you can use in your own code or spreadsheet rather than something you run directly. The exchanges covered include NSE and BSE in India, NASDAQ and NYSE in the United States, KOSPI in South Korea, SIX in Switzerland, TSE presumably referring to a Tokyo or Toronto exchange, LSE in London, and DUS and FWB, which are German exchanges based in Dusseldorf and Frankfurt. The repository also includes a second file called currencies.csv, which lists thousands of foreign exchange currency pairs. The README itself is short and does not go into detail about how the data was collected, how often it is updated, or what license applies to reuse. Because this is a data file rather than an application, there is no install process, code to run, or command line interface described. Anyone wanting to use it would download or reference the CSV files directly and pull the rows they need into their own scripts, spreadsheets, or trading tools.
