Traders often use a combination of macroeconomic calendars, Fed speeches, and central bank meeting minutes to stay ahead of USD trends.

During the 2022 inflation spike, the Federal Reserve raised rates aggressively. As a result, the USD appreciated significantly across the board. Traders who enrolled in a Forex Course learned how to anticipate rate hikes using CPI data and forward guidance from the Fed. By applying macroeconomic analysis alongside technical patterns, they captured strong trends in USD/JPY and EUR/USD throughout the year.
