To speed up the download process, you can configure the downloader to use up to 20 simultaneous connections to minimize the download time. Also, you can have YGQD download data for a specific time period. Once you have downloaded data, you can have the program download only the most recent missing data. Also, Yahoo! offers both adjusted data, which adjusts the prices for dividend distributions and splits, and unadjusted data (Google and MSN only offer adjusted data). Both Yahoo! Finance and MSN offer data back to the start of 1960, while Google’s data goes back to the start of 1970. When downloading data, you can have YGQD download all available data for a given symbol, which is useful when you are just establishing your database. You can specify that the data output be saved in either CSV format for Excel or as a text file.
YGQD uses ticker lists stored in text files as input and generates data files containing the downloaded data, one symbol per file. Version 2.9.1.0 claims to support downloading from QuoteMedia, but beta version 2.9.2.0 has QuoteMedia support disabled-apparently due to changes in the QuoteMedia downloading protocol that have rendered it non-functional. The latest version of this freeware program can download free daily, weekly, monthly, quarterly, or yearly historical quotes from Yahoo! Finance, Google, and MSN Money. One of these is the free Yahoo! & Google Historical Quotes Downloader YGQD from. This has changed over the last few years, as software makers have designed downloaders that will retrieve free historical data for a collection of tickers. However, this was not a viable solution for those looking for historical data across a number of tickers, especially for those using technical analysis and backtesting software. For many years, sites such as Yahoo! Finance and MSN Money have allowed users to download price and volume data of individual stocks and mutual funds.
One of the many benefits of the Internet is that is has brought a tremendous amount of high-quality data to the masses at little or no cost. Yahoo! & Google Historical Quotes Downloader retrieves end-of-day price and volume data from free Internet sources.
