The primary objective of Unfair
Advantage (UA) is to allow you to
export end-of-day (EOD) quotes to
third-party software. You store the data on
your disk in a compressed format and then
convert it to a format that the third-party
software can use. The compression is so
efficient that it lets you get by with as little
as one gigabyte (GB) for US stocks and
indexes, and only requires two GB for
options. Much of the data goes back 20
years and some of it 60 years. CSI (Commodity
Systems, Inc.) prides itself in its
accurate data, which is why companies
such as Yahoo Finance! use CSI to provide
EOD quote data to users.
UA includes charting but it is not
equipped with all the bells and whistles
you find on full-featured products.
Several techniques are available to create
continuous commodities contracts,
and UA covers all of the world’s major
markets. If you are looking for a costcompetitive
and accurate EOD datafeed,
this is the product you want.
Commodities contracts
If you have a brokerage account that allows
you to trade commodities, you can probably get quotes on a limited number
of contracts, such as those trading on the
CME (Chicago Mercantile Exchange). If
you want to backtest commodities, you’ll
want to create a “continuous” contract.
Commodities contracts usually have a
limited life because there is a delivery
date involved. A continuous contract
allows you to have a price series that is
longer than any single contract. UA has
several techniques for creating continuous
contracts for commodities traded on
exchanges all over the world. The tabs
at the top of Figure 1 such as nth nearest,
perpetual, back-adjusted, and Gann
are all different techniques for creating
a continuous price series.
One note about terminology: When
UA refers to a series, it is talking about
a series of individual contracts that have
been linked together to create a single
continuous contract. Two terms that any
commodities trader needs to know are
open interest (OI) and volume. Open
interest refers to the number of contracts
currently being held, and volume refers
to the total number of contracts bought
and sold. The differentiation is important
because it can signal buyer expectations
versus liquidity. A useful technique in
creating a continuous contract is to start
using the next contract when the OI on
that next contract equals the OI on the
previous contract. This process of going
from one contract to the next is called
rollover.
