Available Data Sources

1. Free data sources used by SSChart

SSchart has several free data source on the internet that it uses to collect historic daily, weekly and monthly data for US securities. It also collects a combination of delayed and ECN quotes during market hours to display and save intraday charts. These are not as good as a dedicated subscription source. There is now a free backfill but it is delayed and limited to the last 500 minutes for US Stocks only, but it may be good enough for the occasional trader.

2. Data Sources for International Markets

SSChart can import data from text files into a chart. Virtually any comma or semicolon delimited format can be accommodated. (Note: data for US markets is automatically downloaded by the program from the site selected under the {Data | Internet Sources} menu item. For markets not configured there you will need to import the data from another source, like the one below.)

Historic daily, weekly, and monthly data for nearly every market in the world can be downloaded for free from: http://www.downloadquotes.com by signing up for a free membership.

When downloading data from the above site set the download file format as follows:

The field order doesn't really matter. Set the import data specification in SSChart to "Use header in File". The name field is optional. For US markets SSChart has a symbol database from which it can get the name. If you are getting data for stocks in a market outside the US, the name will not be in our database, so it will not appear in the chart along with the symbol (ticker) unless you include the name in the download. However once it is loaded into SSChart's internal binary files, it no longer is needed in the import file, so you can save some download bandwidth by omitting it from subsequent update downloads. You can download data for several years for the stocks you want to follow, and then just download the updates after that. The updates can all be in the same file, and SSChart can automatically find them there when the {Data | Import Settings} is correct. (See the program help under {Help | Contents} for more information.

Markets in the following countries supported:

Australia, Belgium, Brazil, Canada, China, France, Germany, Greece, Hong Kong, Italy, Japan, Malaysia, Netherlands, New Zealand, Norway, Singapore, South Korea, Spain, Sweden, Switzerland, U.K., USA, Venezuela

3. Broker supplied data

If you have an account with Interactive Brokers, SSChart can get realtime quote data from TWS via the built-in socket interface (free during trial, continued use requires monthly lease). Historic intraday data backfill is now available (the most recent 24hr period only). SSChart still has free source available for daily, weekly, monthly historic data. The capabilities with this source will be live intraday charts for symbols you are collecting data for (with backfill for the current session), and time&sales records. You can chart stocks, futures, options, and indices.

4. Subscription data from myTrack

SSChart gets realtime and historic data from myTrack via the SSQRouterMT quote router program (included with SSChart download, continued use requires monthly lease). This can provide live intraday charts, historic backfill of intraday data (up to 15 days back), daily, weekly, monthly data. Time and Sales, ECN orderbook, and Nasdaq Level II. You must have enabled the "SDK" entitlement to your myTrack account. For about $150/month (counting fees to myTrack and us) you can get live data and orderbooks, along with time and sales logs of all symbols you are watching.

5. Yahoo MarketTracker realtime quotes

If you subscribe to Yahoo MarketTracker realtime quotes, you can use them in SSChart also. You must first login to Yahoo and start the MarketTracker from the browser, then you will be able to start quotes in SSChart with "Yahoo US (Realtime)" selected as the quote source under {Data | Internet Sources.. | Quote Data}. (Note this interface does not provide intraday backfill, so you must collect the data to build intraday charts in realtime).
