I use Yahoo finance to get financial data. How do I get a list of all the ticker symbols in NYSE, NYSEMKT and NASDAQ stock exchanges. (Or even just one of the exchanges).

For the company news RSS feed there is only one parameter: You can find out the ticker symbol for a specific company using the Symbol Lookup feature on Yahoo! For example, to get news items for Yahoo!

Finance returns an RSS 2. RSS is an XML document containing a single channel element representing the feed, several elements containing metadata about the feed itself, and one or more item elements describing individual items within the feed. Each item element contains a news item. If the request contained multiple ticker symbols to search, news items for all companies are returned as individual item elements. Note that the feed simply returns the most recent 25 news items for all the ticker symbols in the request; it does not distinguish which item goes with which company.

The criteria used in this ranking includes:. FINVIZ offers a well established list of both fundamental and technical scan filters, and all results are built on the fly. Perhaps my favorite feature is the ability to be able to hover over any stock ticker to see a stock chart of that stock pop up instantly. This is one feature that none of the other stock scanners reviewed below offers. The free stock screener provided by Google Finance is centered around a very easy to use interface with some visual flare.

Speed is not an issue and there is only a small learning curve required for use. The major complaint I have though is the selection of criteria able to be utilized to perform scans. There is hardly any technical filters, and the fundamental filters are fairly standard. Results can be clicked for quick access to the respective quote page on Google Finance, a feature also provided by Yahoo Finance.

Application returns NaN anytime an observation does not exist. This is the method that Yahoo employs. As the week progresses, the open will stay the same Monday morning opening but the high, low, close, and average volume will fluctuate depending on what happens throughout the week.

This way you don't have to wait until Friday for the current week's print. This logic applies to the monthly data as well. The uploaded file must be a CSV.

Tickers you wish to get data for must all be included in the first column of the spreadsheet, one ticker symbol per row. Any ticker that has historical data on Yahoo! What happens if I request data for a symbol on a day where there is no data? The application takes into account days of no data and properly aligns the series. Any observation with no data point will have a user-selected value, either an NaN or 0 printed. For example, US markets did not trade on July 5, however markets in Argentina did.

For days where all input symbols have no data, the observation is excluded from the download. With time series data, using fill forward is extremely common so that the "last known value" is available at every time point. Select fill forward to make this occur. Fill backward is less common in time series data you don't know tomorrow's values today , but is included for completeness. If this box is selected, observations will be returned in ascending order start date first to end date.

For example, selecting daily observations between July 5, and December 31, in ascending order will return observations starting at July 5, and ending at December 31, What is included when the "Include column headers" box is checked? When this box is checked, the ticker symbols will be included at the top of the data series.
