Drawbacks of other historical data sources:
- Many sources of historical data such as Yahoo Finance
only allow you to download a very limited number of
symbols at once. To attempt to gather years of historical
stock data in this fashion is prohibitively time consuming.
- Other sources will allow you to buy historical data
for thousands of ticker symbols but the data will often
reside in thousands of separate excel spreadsheets or
comma separated files (ascii format). The data from
these sources needs to be combined and/or imported if
one is desirous of organizing it in a fashion which
lends itself to complex analysis such as in a relational
database or data warehouse. Opening up thousands of
individual spreadsheets to look for data is highly impractical. |
