What “closing before news” means
“Closing before news” generally refers to exiting (or reducing) an open position before a scheduled economic or market-moving announcement. The goal is to reduce exposure to volatility that can occur around releases.
It is helpful to separate the idea from expectations. The mechanics are usually simple—close an existing position before a time window around the release. What is not simple is what happens after you close: prices can still move, your fill price may differ from what you expected, and transaction costs may change your net result.
A common misunderstanding is treating this as a complete risk removal step. Even if you exit before the release time, you can still face uncertainty related to execution and market conditions.
How it works in practice
Consider an open position you intend to close. Your outcome depends on variables you control less than you think:
- Time choice: “Before news” requires defining a cutoff. A cutoff that is too late may still put you in the volatility window; a cutoff that is too early may leave you exposed to unrelated price movement.
- Order execution: Closing usually relies on an order being filled at a price and within a time. Fill quality varies with liquidity.
- Transaction costs: Spreads, commissions, and any platform fees affect the difference between your intended exit price and your actual net result.
- Assumptions about direction: Many people focus on one expected direction of movement. That creates an implicit assumption that the release outcome maps neatly to price behavior.
Evidence-like example (with explicit assumptions)
Example assumptions (made for demonstration only, not as a prediction):
- You open a trade at a known price.
- You plan to close at a specific cutoff minutes before an announcement.
- You model a “range” of possible exit prices due to volatility.
A mistake often appears when the trader assumes the exit will occur exactly at the modeled price. In reality, even “closing before news” can result in a worse-than-expected fill if liquidity thins.
Another frequent misunderstanding is extrapolation: people look at historical charts around similar announcements and treat the pattern as a rule. Historical reactions do not establish future outcomes, especially because liquidity, market participants, and the context of the broader trend can differ.
Common mistakes (and what to check)
1) Confusing the concept with certainty
Mistake: Assuming you have “done enough” once the position is closed. Reality: closing reduces exposure, but does not remove execution uncertainty, transaction costs, or post-close price moves.
Neutral check: Write down what risk you are trying to reduce (e.g., volatility around release), and list what you are not reducing (e.g., slippage, spread changes, market gaps after your fill).
2) Using an unexamined time rule
Mistake: Using a fixed “N minutes before” rule without considering that announcement timing and liquidity conditions can vary.
Neutral check: Define your cutoff relative to the release you are referring to, then test whether your assumptions about liquidity and order-fill behavior match typical conditions.
3) Ignoring costs and fill quality
Mistake: Estimating profit and loss using mid prices or a hoped-for exit, then forgetting that spreads and commissions change net results.
Neutral check: Use explicit assumptions for spreads/fees and compare “expected” vs “possible” net outcomes based on different fill prices.
4) Treating historical price reaction as a forecast
Mistake: Believing that because something happened before, it will happen again in the same direction or magnitude.
Neutral check: If you reference past moves, frame them as context only. Do not treat them as a standalone indicator or a standalone pattern that guarantees a result.
5) Leaving assumptions unstated
Mistake: Example calculations that omit key inputs—like the cutoff definition, whether the position is fully or partially closed, and which price you assume for fills.
Neutral check: For any scenario, state assumptions clearly (cutoff timing, whether the close is full, and how you translate fill prices into net results).
Limitations and risks you should accept
Even with disciplined “closing before news,” uncertainty remains:
- Execution risk: Your closing order may not fill at the price you expect. - Cost sensitivity: Spreads and fees affect net outcomes. - Context variability: Liquidity and market sentiment can differ across events.
