US Treasuries: Bonds are used for a diversification tool, as well as income, in most portfolios. STA covers risk-free treasuries, rather than corporate bonds, in an attempt to further diversify this asset class (bonds) away from the corporate risk which is inherent in both equities and corporate bonds.
Commodities: SeattleTA covers the two most popular and important commodities on the planet: Crude Oil and Gold. Despite recent moves toward clean energy, the "modern" world still runs on oil. Gold, or the 'barbaric relic' has maintained its importance for thousands of years.
Currencies: We follow the US Dollar, Euro, and the Japanese Yen. The Yen is a broadly traded, liquid currency and tracking it helps in trading the Nikkei, just as following the Dollar helps in trading US domestic markets.
MTA Podcasts: The Market Technicians Association sponsors a weekly interview with a technician of importance each week. Past guests have included Robert Prechter, Martin Pring, Tom DeMark, and Larry Williams.
Library: The library includes both videos and articles which should be of interest to anyone following the markets as well as those who would like to increase their knowledge of technical analysis.
