How to Trade the News: Volatility, Spreads and Pullbacks
Why prices move on the surprise, not the headline, why spreads widen and stops slip at releases, and a patient pullback approach with plain risk controls.
· 9 min read
TL;DR
Markets react to the gap between the actual figure and what was expected, not to the headline number itself. In the seconds around a major release, spreads widen and liquidity thins, so entries and stops fill worse than planned. Most traders do better by reducing size, widening stops and waiting for the first spike to settle, or by staying flat.
Scheduled economic releases are among the few moments when the whole market looks at the same number at the same second. Prices can travel further in a minute than they usually do in an hour, and then reverse. That makes news attractive to short-term traders and dangerous for the unprepared, because the things that normally protect a trade (tight spreads, reliable stop fills, orderly price movement) are the first to go.
This article covers why the market reacts the way it does, what changes in execution around a release, and one patient method for trading the aftermath instead of the first second. None of it is a prediction tool. It is a way to decide how much risk a news event deserves, including the option of none.
Price reacts to the surprise, not the number
Every major release on an economic calendar carries three figures: the forecast, the actual and the previous. The forecast is a consensus, usually the median of estimates from economists surveyed by a data vendor. By the time of the release, traders have already positioned for that forecast, so the forecast is largely in the price. What moves the market is the difference.
If US payrolls are forecast at +150,000 jobs and come in at +150,000, the headline can be strong or weak in absolute terms and still barely move the dollar. If the forecast is +150,000 and the actual is +200,000, the surprise is +50,000 and the dollar usually reacts. A big absolute number that matches expectations is a non-event, while a modest number that misses badly can start a trend.
Two other things complicate the picture. The first is revisions: many releases restate the previous period at the same time, and a revision can outweigh the new figure. The second is that traders compare the data with what it implies for central bank policy. A hot inflation print matters mostly because it changes the expected path of interest rates. The mechanism is covered in how central banks influence forex prices and what moves forex prices.
What changes in execution around a release
Liquidity providers, the banks and market makers who quote the prices you trade, do not want to be caught holding the wrong side when the number lands. In the minutes before a major release they often widen their quotes or pull them back, and for a short time after the release the price can jump between quotes with little or nothing traded in between. Three effects follow.
- Wider spreads. The gap between the bid and the ask can be several times its normal size. You pay it on entry and again on exit. See the anatomy of a forex quote for how the spread works.
- Slippage. A stop loss normally becomes a market order once its level is touched, and it fills at the next available price. In a fast move that price can be well beyond your stop. The same applies to pending entry orders.
- Gaps and requotes. Price can skip levels entirely. Some brokers pause or requote orders for a few seconds, and your platform may freeze under load.
Spreads also matter to stops in a less obvious way. A long position closes at the bid, so a stop on a long trade can be triggered by the bid falling even if the mid price has barely moved. When the spread is wide, stops sit closer to the market than they look. The broader cost picture is in costs of opening and holding a forex trade.
A worked example: same trade, two environments
Assume a $10,000 account, risk of 0.5% per trade ($50), and a EUR/USD position where one pip is worth $10 per standard lot. These are round, illustrative numbers. The point is how the same $50 of risk buys a very different position size once news conditions are priced in.
| Normal conditions | Around a major release | |
|---|---|---|
| Spread | 0.6 pips | 4 pips |
| Stop distance | 20 pips | 40 pips |
| Allowance for slippage | 0 pips | 5 pips |
| Worst-case loss in pips | 20 | 45 |
| Position size for $50 risk | 0.25 lots | 0.11 lots |
| Spread cost at that size | $1.50 | $4.40 |
The arithmetic: in normal conditions, $50 divided by (20 pips x $10) is 0.25 lots. Around the release, $50 divided by (45 pips x $10) is about 0.11 lots, which risks roughly $49.50 if the full 45 pips are lost. The spread is paid on the whole position, so 4 pips at 0.11 lots is $4.40 against 0.6 pips at 0.25 lots, which is $1.50. The trade is less than half the size, the stop is twice as far away, and the cost per unit of risk is much higher. A news trade needs a bigger move to be worth taking.
The usual reactions after a release
Price action after a major number tends to fall into a few patterns. None is reliable on its own, but knowing them stops you chasing the first candle.
- Spike and continue. The surprise is large and clear, price jumps and keeps going in the same direction as positioning unwinds.
- Spike and reverse. The first move is an overreaction or a stop run, and price returns to where it started, sometimes within minutes.
- Two-way whipsaw. Price spikes up, then down, then up again as traders digest the headline, the revision and the details in separate steps.
- Little reaction. The result was close to the forecast and the market was waiting for something else, such as a central bank decision.
Traders who place pending buy and sell orders on both sides of the price before a release, hoping to catch whichever way it breaks, are exposed to the whipsaw. One order can trigger, reverse and stop out, then the other can trigger and do the same. With wide spreads and slippage, this tends to lose on both sides.
A patient method: wait for the pullback to a mapped level
Instead of trading the first second, some traders let the spike happen and look for an entry once price has settled. The idea is to use a level you prepared before the event, so the decision is not made in the middle of the chaos. A typical sequence looks like this.
- Before the release, mark the support and resistance zones on a higher timeframe such as the 4-hour or daily chart. See support and resistance zones for how to draw them.
- Do not hold a position or pending orders through the number unless you have decided to accept the risk in advance.
- Let the first spike play out. Watch where price goes relative to your marked levels, not the headline.
- If price pulls back to a prepared level and shows a reaction there, for example a candle on the 15-minute chart closing back in the direction of the move, that can be an entry with a stop beyond the level.
- If price slices through the level without pausing, or the spread is still abnormally wide, skip the trade.
This is a way to structure a decision, not a promise that pullbacks happen. Sometimes price never returns to the level, and sometimes it returns and keeps going. The method trades a bigger chance of missing the move for a better-defined risk. Whether it suits you can only be judged by testing it on a demo account across many releases.
Risk controls for news
- Reduce size. Cut position size so that a worst case with slippage still equals your normal risk, as in the table above. Many traders go further and use half of their usual size or less.
- Widen stops, but only with smaller size. A wider stop with the same size just means a bigger loss. See where to place stop loss and take profit orders.
- Check margin. A spike can push a leveraged account towards a margin call very quickly. Leverage and margin explains why.
- Know your broker's rules. Ask whether it offers guaranteed stops, what it does with orders during fast markets, and whether spreads are fixed or variable.
- Stay flat. Not trading a release is a legitimate decision. Closing or reducing open positions before a major event removes the risk entirely, at the price of missing a possible gain.
Make the event part of your routine
Check the calendar before the session starts, note the release times in your own time zone, and decide in advance what you will do for each event: trade it, reduce size or stay flat. That decision belongs in a pre-market routine, not in the five seconds after the number appears.
Trading around news carries a high risk of loss, particularly with leverage. Most retail traders lose money, and the conditions described here are exactly when a stop can fill far from where you placed it. This article is education, not advice.

Quick answers
Why does price sometimes fall on good news?
Because the market was expecting something better, or the details and revisions were weaker than the headline. Price responds to the gap between the actual figure and the consensus, and to what that means for interest rate expectations.
Should I trade the first move after a release?
The first seconds carry the widest spreads and the most slippage, and the move often reverses. Many traders wait for price to settle and trade a level they marked beforehand, or skip the event.
What is a whipsaw?
A whipsaw is a sharp move in one direction followed by a sharp move back, often more than once. It can stop out traders on both sides of the market within a few minutes.
Is it safe to leave a trade open during a major release?
It carries extra risk because a stop can fill well beyond its level and margin can be tested quickly. If you hold through a release, use a smaller position than usual and accept in advance that the stop may not give the exit price you expect.
