Comparing data vendors
by Steven B. Achelis
If you think choosing stocks and/or commodities to buy is difficult, try selecting a data vendor to use
with your technical analysis software. At Computer Asset Management we have written software (The
Downloader) to automatically "download" data from 13 vendors for use with our MetaStock technical
analysis program and other compatible software. We found significant differences among these vendors,
as you'll see in Figure 1.
We gathered this information to assist our customers in choosing a data vendor, but keep in mind that
there may be advantages to the various data vendors based on criteria not shown here. For example, it is
very difficult to quantify the quality of data or the quality of technical support offered by the data vendor
and/or software developer. Computer Asset Management believes this information is accurate, but cannot
guarantee that it isówe suggest you contact the data vendors for additional details.
Also, these comparisons were based on collecting data used by the MetaStock program. Features of the
data vendors that are not used by MetaStock, such as news and weather reports, were not compared. We
rated manuals and ease of use on a scale of 1 to 10 (with 10 being the best) based on feedback that
Computer Asset Management has received from our customers and on Computer Asset Management's
own experiences working with these services.
