There are quite a few and it all depends on each regions status. Here are a few that I keep an eye on.
Federal Open Market Committee (FOMC) Meetings and Fed Actions.
Index of Leading Economic Indicators (LEIs).
Gross Domestic Product (GDP).
Balance of Payments.
Consumer Price Index (CPI) and Producer Price Index (PPI).
Housing Starts and New and Existing Home Sales.
Durable Goods Orders.
Institute of Supply Management (ISM) Index.
Industrial Production and Capacity Utilization.
Personal Income and Personal Spending.
Also, keep an eye on the Weekly Economic Report to see which reports are coming out and the impact they may have. I believe there is a link somewhere in Babypips.
