[size=18:54a814a3cd][color=indigo:54a814a3cd]MasterDATA Index & ETF Composite Data[/color][/size:54a814a3cd] Currently, consider MasterDATA a data provider. Just like Reuters, eSignal and many others provide you price data, MasterDATA supplies composite data. For many, the composite / breadth charts and reports in our free subscription section are all they ever need or want. For others, wishing to construct their own analyses, we offer downloadable historical composite / breadth datafiles. If you are unfamiliar with composite / breadth analysis take a look at Greg Morris' recently published book in the right column. Greg is one of the major "authorities" on the subject and his new book is already highly praised. While MasterDATA currently supplies composite data and, hopefully, enough information about constructing composite / breadth indicators to get you started, our plans for the near future include much beyond this. To keep informed of our progress, sign up for a free subscription. I don't send many emails and, when I do, they are informational, never marketing pieces. Briefly, composite (or breadth) data is what the components of an index or ETF are doing as a whole. What the component issues are doing is also called "internals". For instance, in the S&P 500, how many issues went up or how many down for the day. What was the total up volume in all components on issues that advanced? How many are trading above their 200 day moving average? The measurement can be taken using any criteria (technical analysis indicator or even fundamental) used for an individual stock and finding the total number of component stocks that display that particular characteristic. Using composite data to trade indexes or ETFs provides a whole new and very insightful array of analysis tools. This method of analysis has been overlooked for years simply because the data is difficult to maintain and, until now, was not available except on the the NYSE, AMEX and NASDAQ Exchange Composites. Many well known "breadth" indicators are in wide use today such as the McClellan Oscillator and Summation, TRIN and Advance/Decline Line but have been limited to analysis of these broad markets only. Now, the same analysis techniques and indicators (and many more yet to come) can be applied to trading actual securities. To my knowledge, MasterDATA.com is the only source on the internet for this historical composite data. Data formats include MetaStock (includes the MasterDATA Composite Plug-in) and CSV (MS Excel).
