Many "Surprises" in the Market Are Actually Already on the Calendar

There's a common misconception in the market that volatility stems from unexpected events. However, if you compare the trading days with the largest swings in a year, you'll find that most of them fall on pre-announced dates—a specific inflation data release, a monetary policy meeting, or an employment report. True surprises are rare; most so-called "black swans" are simply dates that no one bothered to note down in advance.

The economic calendar is this schedule. It doesn't predict market movements; it simply answers one question: When will what numbers be released, and in which country? Those who use it effectively treat it as a scheduling tool, while others see it as an incomprehensible table. The difference usually lies in three numbers.

Previous, Forecast, Actual: These three numbers in the economic calendar are the market's script.

Three Numbers: The Market Trades the "Difference," Not "Good or Bad"

Every economic data point provides three values: the previous value (the result released in the prior period), the forecast (the general prediction derived from market surveys), and the actual (the number truly released for the current period).

A common mistake for beginners is to compare the "actual value" with "good or bad": going long if unemployment falls, or short if inflation rises. However, prices have already digested the "forecast" before the data is released. What truly drives market movements is the difference between the actual value and the forecast, often referred to as the "expectation gap."

Two real examples illustrate this distinction. On September 3, 2026, the US August ISM Services PMI was released with a previous value of 54.1, a forecast of 54.3, and an actual value of 55.4. The number itself wasn't astonishing, but it was 1.1 points higher than the market's general forecast, and this was the part that needed to be repriced that day. The day before, the August ADP Employment Change was released with a previous value of 46,000, a forecast of 47,000, and an actual value of 38,000. The direction was exactly opposite: while the absolute number was still positive growth, it was nearly 10,000 below expectations. Both were "positive numbers," but one was hawkish, and the other dovish.

Therefore, the correct way to read the calendar is: first look at the forecast, then wait for the actual, and finally only care about how big the difference between the two is and in which direction.

Star Ratings: Condensing Over Two Thousand Indicators into a Manageable List

The number of economic indicators released globally every day far exceeds imagination. Our economic calendar currently includes over 2,300 indicator series from 119 countries and regions, totaling over 20,000 historical entries, most of which already have actual values, with historical data going back to September 2025.

Reviewing all of them is neither realistic nor necessary, so a system of importance ranking is needed. Five stars is the highest:

  • Five Stars (a dozen or so): US Nonfarm Payrolls, CPI, Core PCE, GDP, Federal Reserve interest rate decisions, as well as the monetary policy outcomes and press conferences from the European Central Bank, the Bank of Japan, and the Bank of England. These almost invariably trigger immediate cross-market reactions.
  • Four and Three Stars: ISM and PMI series, Initial Jobless Claims, Retail Sales, various countries' GDP components, etc. Individually, they may not cause a stir, but several consecutive periods of deviation in the same direction can alter market judgments on policy paths.
  • Two Stars and Below: A large number of regional, low-frequency, or specially defined data points. These can generally be skipped unless you are specifically trading related instruments.

A practical approach is to focus on three-star events and above each week, using the rest as reference for post-mortem analysis.

Time: The Three Easiest Pitfalls

  • Time Zones. US data is often released at 8:30 AM local time, which translates to 8:30 PM or 9:30 PM in UTC+8, also considering daylight saving time changes. The calendar page uniformly displays times in UTC+8 to eliminate this prone-to-error mental calculation.
  • Multiple Data Points at the Same Time. In the minute Nonfarm Payrolls are released, unemployment rates, hourly wages, and prior value revisions appear simultaneously. The first wave of market movement is often the result of a mixed effect of several numbers, and focusing on just one can lead to misreading the direction.
  • Revisions. Many indicators revise historical data in subsequent periods. A significant downward revision can sometimes be as impactful as the current period's data itself.

Beyond Economic Data: Earnings and Holiday Schedules

Two other aspects of the calendar are often overlooked but are equally crucial for position management. The earnings calendar includes over 20,000 corporate earnings release schedules, many of which involve companies related to crypto, hashrate, and the semiconductor industry. The overnight gap risk on earnings days is something that should be checked before holding positions overnight. The holiday calendar addresses another issue: major global markets do not share the same holidays. When a market is closed, liquidity for related instruments can significantly thin out, making prices more susceptible to movement by small amounts of capital.

Indicator Detail Pages: Context Beyond the Numbers

A single number is often not enough to make a judgment. Indicators like US Nonfarm Payrolls, US CPI, and Federal Reserve Interest Rate Decisions all have dedicated pages. Besides historical data series, they explain their statistical methodology, which agency releases them and at what frequency, why the market pays attention to them, and how an unexpected outcome is usually interpreted.

This content is common knowledge for experienced traders but essential for newcomers—knowing that the word "core" in inflation data means excluding energy and food prevents being misled by a highly volatile component.

A Replicable Usage Strategy

  • Schedule on Sunday Evening: Mark out all three-star events and above for the week, noting specific dates and times, to decide which days are not suitable for holding heavy positions overnight.
  • Check Ranges Before Data Release: Quickly review the actual value fluctuation range of the indicator in recent periods to establish a mental benchmark for "what constitutes a surprise."
  • After Data Release, Focus on Two Things: The difference between actual and forecast, and whether the previous value was revised. Other interpretations can be made at leisure.
  • Let Data Come to You: Once important indicators are released, the triplet of values will automatically feed into the site's news stream, eliminating the need to constantly refresh the page.

Previous, Forecast, Actual: These three numbers in the economic calendar are the market's script.

By laying out the schedule in advance, trading transforms from "reacting to surprises" to "managing rhythm." This is perhaps the most underestimated value of the economic calendar: it cannot predict rises or falls, but it can prevent people from being caught off guard by things they could have known in advance.
