This item downloads U.S. Crude Oil and Liquid Fuels Supply, Consumption, and Inventories historical statistics data. The data is retrieved as an Excel file from the Energy Information Administration website (Official Energy Statistics from the U.S. Government), it is then parsed and updated so it can be inserted into the quotes database.
In order for this data to be added into the database, a transformation using the Pre-Script is necessary. In a nutshell, the script reads that data and creates its own properly formatted lines. Only 33 lines of code were necessary.
The data is monthly updated and can be downloaded by typing a year in the 'Year' textbox. You can also download future years (2010 for example) to get estimations of the future values of these items. The Energy Information Administration says that the estimations or projections are generated by simulation of the EIA Regional Short-Term Energy Model and that the macroeconomic projections are based on Global Insight Model of the U.S. Economy.

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
