ARMFThe forex economic calendar and event risk
The forex economic calendar is the only service in this section that calculates nothing: it shows a schedule. But it is exactly that schedule that explains part of the losses which look like chance: a stop filled ten pips worse than the level, a spread five times wider than usual, a move in both directions within a minute. We take apart how to read the calendar from the risk point of view and which rules follow from it.
The calendar is a reference service: a list of macro data releases and speeches with the date, the time and an importance rating. It does not predict the move and gives no signals, but it tells you in which minutes price behaves differently from the rest of the time.
What the forex news calendar shows
A row of the forex news calendar consists of several fields, and not all of them matter for risk management. The analysts' forecast is the least useful: the market reacts to the gap between the fact and the expectation, not to the value itself.
| Field | What it means | How it affects risk |
|---|---|---|
| Release time | the moment the data comes out | the minutes in which the spread widens |
| Currency | which economy it belongs to | which pairs are affected |
| Importance | the service's rating of the impact | a rough filter: three levels |
| Previous | the value of the previous period | the base for comparison |
| Forecast | the analysts' consensus | what is already in the price |
| Actual | the published value | the move comes from the gap with the forecast |
The practical conclusion is simple: what to look at is the time and the importance, not an attempt to guess the value. The calendar is used as a schedule of when execution risk is higher than usual, not as a source of trading ideas.
What happens to the execution price at the moment of release
Three effects work at the same time, and all three hit the risk calculation. The loss at the stop calculated in advance stops being an upper bound.
The difference between the buy and the sell price grows several times over for a few minutes. A tight stop is then touched by a move that did not exist at the mid price.
costsThe order is filled at the first available price after the level is touched. On a gap in quotes this can be noticeably worse than the stop level.
executionA move in both directions within a minute knocks out buyers and sellers alike. The direction of the first reaction often flips to the opposite one.
priceRequotes and delays: an attempt to move the stop or close the position by hand in those seconds may not go through.
managementOne rule follows from these four points, and it requires no forecast: if a position is open and an important release on the currency of the pair is ten minutes away, the risk of the trade at that moment is higher than the calculated one.
Which events change the risk the most
The list below is sorted by impact on the currency market rather than by frequency. Look up the exact release times in the calendar itself: they shift with the change to summer time.
| Event | What is published | Why it matters for risk |
|---|---|---|
| A central bank rate decision | the rate and the accompanying statement | a reversal of the pair's trend within minutes |
| A central bank chief's press conference | comments and answers to questions | a stronger move than on the decision itself |
| US employment data | the change in the number of jobs | a sharp move across all dollar pairs |
| Inflation | the consumer price index | a repricing of rate expectations |
| GDP data | the growth rate of the economy | a move of average strength but a lasting one |
| Unscheduled statements | politics and geopolitics | absent from the calendar by definition |
The last row explains the limit of the whole tool: the calendar covers the known schedule risk and says nothing about the unknown one. That is why a stop is always placed, not only before a release.
The rules that follow from the calendar
None of them requires guessing the direction. All four concern the size and the moment, that is what the trader actually controls.
Where to look and how calendars differ
There are many services and the data in them is the same — the differences are in the presentation and in the small things that become visible with daily use.
The calendar and risk: short answers
- Do positions have to be closed before the news
- Not necessarily. The decision depends on the strategy: a release interferes with intraday entries far more than with positions held for several days.
- Does a guaranteed stop help
- Some brokers offer such a service for an extra fee. It closes the gap risk but reduces the expectancy of the system.
- Can the direction be predicted from the forecast
- No. The forecast is already in the price, and the move comes from the gap between the fact and the expectation and from the tone of the comments.
- What to do with an open position at the moment of release
- Change nothing by hand: orders go through badly in those seconds. The decision is taken in advance — before the release, not during it.
- Does news on another currency have an effect
- It does, if that currency is in the pair. A release on the euro moves both EUR/USD and EUR/JPY, even though the dollar and the yen have nothing to do with it.
- Is the calendar of any use in long-term trading
- It is, but in a different way: what matters are central bank decisions, not weekly statistics. A check once a week instead of daily.
Frequently asked questions
What the economic calendar is and why a trader needs it
It is a schedule of macroeconomic data releases and official speeches with the time, the currency and an importance rating. For risk management it is needed as a list of moments when order execution is worse than usual and volatility is higher.
How the calendar is connected to risk management
Directly: the risk calculation assumes the loss is limited by the stop. At the moment of a release that assumption weakens — the spread widens and slippage grows, so the actual loss can exceed the planned one.
What the importance of an event in the calendar means
The service's rating of how strongly a release usually moves the market. It is subjective and differs between services, so it is better to go by the type of the event: rate decisions and employment data matter more than secondary indices.
Should the size be reduced before a release
This is the most reliable of the available techniques. Reducing the share of risk also reduces the loss on a bad fill, unlike widening the stop, which increases the price of it triggering.
Does a stop-loss save you during the news
The stop stays mandatory, but it does not guarantee the execution price. On a gap in quotes the order is filled at the first available price, and it can be noticeably worse than the level you set.
Why does price first go one way and then reverse
The first reaction usually trades the headline, and the next one the details of the release and the comments. For a trader this means that an entry in the first seconds after the data comes out is the most expensive trade in terms of costs.
Where to look at the calendar: in the terminal or on a site
MetaTrader 5 shows events right inside the platform and marks them on the chart, but the set of events there is narrower than on specialised sites. People often use both.
Can notifications about events be set up
Most services allow an alert a few minutes ahead. That is more useful than keeping the calendar open: the decision is taken in advance anyway.
Do weekends and holidays matter
They matter for liquidity: in a thin market a move on the same volume comes out wider and spreads are larger. The opening of the week after the weekend is a typical place for a price gap.
Should the calendar be taken into account when running an expert advisor
Yes, if the advisor has no news filter of its own. Otherwise the algorithm will open a position a minute before the release by exactly the same rules as in a calm market.
How does the calendar help choose trading time
It shows which hours the main releases on your pairs fall on. Combined with the statistics of your own trades by hour, this gives a simple rule: which intervals not to enter in.
Can the calendar replace market analysis
No. It is a schedule reference, not a source of signals. Its role in the system is to warn about moments of increased execution risk.
