How do traders use all this?

There are few useful tips that can be followed:

1. Keep an economic calendar on hand. Watch for the events when data are due to be released.

2. Know what indicator is gaining the most of attention at any given time as it becomes a catalyst for future price moves. For example, when the U.S. dollar is weak traders will watch closely the inflation indicator.

3. When the difference between the expectations and real results occur, watch for corrections in the market price moves.

4. Pay attention to news revisions if any, the situation on the market can change quickly.
