How to Use an Economic Calendar
What Is an Economic Calendar?
An economic calendar lists scheduled economic events, including central bank meetings, GDP releases, employment reports, and inflation data. Each event shows the expected value, previous value, and actual outcome. For South African traders, the most important events are the SARB repo rate decision, South African CPI inflation, and US non-farm payrolls — all of which directly impact the ZAR.
How to Read the Calendar
Events are color-coded by volatility potential: red for high impact, orange for medium, and yellow for low. Focus on red events if you trade ZAR pairs like USD/ZAR or EUR/ZAR. The calendar also shows the time in SAST (South African Standard Time), so you don’t need to convert time zones. Pay attention to the 'Previous' and 'Forecast' columns — if the actual value differs significantly, expect a strong move.
Step-by-Step Usage
First, filter the calendar by country (South Africa or United States) and impact level (high). Second, note the time of the event and set a reminder. Third, before the event, reduce your position size or close trades to avoid slippage. Fourth, after the release, wait 15–30 minutes for the market to settle before entering new trades. This approach helps you avoid getting caught in volatile spikes.
Practical Example for South Africa
Suppose the SARB is expected to hike rates by 25 basis points. The calendar shows a red alert at 15:00 SAST. You are trading USD/ZAR. Before the event, you close your long USD position. After the announcement, the ZAR strengthens, and you buy USD/ZAR at a better rate. Without the calendar, you might have held through a 200-pip drop.
