How the NQ reacts to news
Two facts explain almost everything that looks irrational about news days: the market already holds the number it expected, and the order book empties just before the release. Neither is folklore, and together they account for «good news, price fell» and for the first move that immediately undoes itself.

The market trades the surprise
Every scheduled release has a published consensus — what economists expect it to say. By the time the number arrives, the expectation is already in the price: everyone who wanted to position for it has done so.
So the reaction is not to the number. It is to the distance between the number and what was expected. A result that would sound excellent on the news can send the market down, because it was less excellent than what had already been paid for.
«Good number, price fell» is not the market being irrational. It is you and the market pricing different things.
Which is also why reading the release itself is rarely useful in the moment: without knowing what was expected, the figure alone has no direction in it.
Why the first move exaggerates
This is the mechanical half, and it follows directly from passive and aggressive orders.
The people who provide resting liquidity are pricing risk. In the minutes before a release they cannot price it — nobody knows what is coming — so they pull their orders. The book thins out, sometimes dramatically, while the chart still looks calm.
Three practical consequences follow, and they are the reason news days hurt people who trade them the same way as any other day:
- The spread widens. A market order can fill several ticks from what you saw.
- Stops jump. A stop-market triggers and fills wherever there is size, which may be far below where you set it — see the article on order types.
- The chart lies about the size of the event. A large candle on a thin book is not the same event as a large candle on a full one, and they look identical.
What is on the calendar
You do not need to follow economics. You need to know when the market's attention will be elsewhere. For this contract that is, in rough order of disruption: the central bank decisions, the inflation figures, the employment report, and the results of the largest companies in the index — which get their own article next.
Most American releases land in the pre-market, before the shares open; central bank decisions usually land in the middle of the afternoon, which is a different problem because you are already in the session.
Check a calendar before the open. Which one hardly matters; the free ones list the same events with the same consensus figures.
The three honest options
There is no correct answer here, and anyone selling one is selling the exciting version.
- Be flat through it. You give up whatever happens and you keep the ability to plan.
- Be positioned in advance, with the risk already sized for it. You are accepting a range of outcomes you cannot control, and the sizing has to assume the bad end.
- Wait for the book to refill and trade what the market decided once everyone is quoting again.
The playbook this site is built on takes a simple line on this, and it is worth quoting as one person's rule rather than as a recommendation: on a news day, either widen the stop or do not trade. What it refuses to do is trade a news day with a normal stop, which is the option most people take by default because they did not look at the calendar.
Unscheduled news
Everything above assumes a countdown. Some events do not have one, and then the same mechanics happen without warning: liquidity vanishes, the move is violent, and the first prices are the least reliable.
There is no preparation for the timing of that. There is preparation for the size of it, and it is the one this whole path keeps returning to: a position small enough that being wrong suddenly is survivable. That is the only defence that works against something you did not know was coming.
