Trading during news: Why do market conditions change?
Trading during news time differs from trading in calmer periods; when economic news is released, liquidity and order execution speed can change, and price may move strongly in one direction and then reverse. Therefore, it is not enough to anticipate the news content; you must understand how the market can react to it and what could invalidate the scenario you set. No movement is guaranteed, and initial responses may not reflect later market direction.
On October 5, 2026, the Economic Calendar on the site lists upcoming events in UTC, including the Bank of Japan Governor Oide’s speech at 06:35, marked high impact, with no published forecast or previous reading. It also includes the US ISM Services Index at 14:00, with medium impact, forecast 55.1 vs previous 55.4, and the Canadian Ivey Purchasing Managers’ Index at 14:00, medium impact, forecast 65.2 vs 64.3 previous. This data helps know when to monitor, but does not reveal price direction or magnitude in advance.
How spreads widen during economic news?
Spread is the gap between the bid and ask prices for the instrument. Around high-impact news, such as an interest rate decision or NFP data, the number of traders willing to offer tight prices may decrease, while orders can change rapidly. As a result, the spread may widen temporarily. This is a market execution condition, not a fixed rule for every news item or instrument.
Widening spreads matter because a trade may start at a less favorable price than usual in calm times. Reaching break-even can become harder, and the stop‑loss execution price may be affected by the available price at execution, depending on order type and broker policies. The current data does not provide an actual spread reading or execution details for a specific instrument; therefore its size or digital impact cannot be determined.
Before the event, review instrument specifications and order conditions, and do not assume the usual spread will stay the same. If its wide spread makes risk unacceptable, opting out during the most volatile moment is worth considering. Also avoid increasing trade size just because price is moving fast; speed of movement does not mean a trade opportunity is better.
Slippage: why execution price may differ?
Slippage is the difference between the price the trader requested and the price at which the order is executed. When prices move rapidly, the requested price may not be available at the moment the order reaches the market, so it is filled at the next best price. The direction can vary; execution may be less favorable or more favorable, and neither outcome can be guaranteed.
Activating stop loss does not necessarily mean that execution will occur at the exact price under all market conditions. Therefore, understand the order type used and its execution conditions, and check the risk management tools available from the service provider. Do not confuse an apparent on-screen price with a guaranteed fill price, especially during a major news release or when liquidity is thin.
The first contrarian move: don’t confuse it with the direction of the news
A movement in one direction may appear after the news, then the price moves back or reverses. Reasons include traders comparing the result to expectations rather than the prior reading alone, or re-evaluating the news details and context. The initial move may be short or followed by another move; no path can be guaranteed in advance.
For example, having an expectation for an economic indicator in the calendar does not tell you how the result will be received, and beating expectations does not force the price to rise. The market may focus on other elements or expectations may have already been reflected in prices. Therefore, avoid treating the first candle after the announcement as a confirmed signal, and consider clear scenarios instead of a hasty decision.
- Continuation movement scenario: The primary trend may continue if price remains firm and does not show data weakening the market interpretation of the news. This scenario is invalidated if price clearly reverses the move or news data change.
- Reverse scenario: The price may retreat from its initial surge if trader sentiment changes or the move is not established. This scenario is invalidated if price regains its initial direction and continues its support.
- Volatility scenario: Price may move in either direction without a clear path, especially with price changes and execution speed. This scenario is invalidated if a stable move in one direction materializes.
These are probabilistic descriptions, not entry signals. Any scenario can fail, so your exit point should be understood before opening the trade, not after losses widen.
Using the economic calendar on the site
Start by identifying the event and its time in UTC, then review the impact, expectation, and prior reading if available. In the current list, the word OIDA is classified as high impact, but the Expectation and Prior boxes are not disclosed; do not infer a figure or direction from them. The US and Canadian indicators are classified as medium impact, with expectations and prior readings listed above. The classification helps organize attention, but it does not guarantee the magnitude of movement.
After that, decide whether you will watch the market only or wait for price stability before evaluating entry. If you are watching the asset, separate the timing of the news from the cause of the move: synchronization alone does not prove the event caused the move. As contextual information, 24-hour instrument notes: Bitcoin 85970.73 (-0.65%), Ethereum 2714.36 (-0.46%), Solana 121.05 (-0.45%), Ripple 1.5119 (-0.57%). These numbers alone are not sufficient to link movement to calendar news, and there is no data here on spreads or execution for these instruments.
In summary, the calendar is a planning and tracking tool, not a tool for certain prediction. Review the event, understand spread and slippage risks, create scenarios with reversal conditions, and do not treat initial reactions as a substitute for a disciplined trading plan. The content is analysis, not investment advice.
Key points
- The spread may widen and the execution price may change around the news, but the extent is not available in current data.
- The initial move after the data may reverse; treat it as a possible scenario, not a certainty.
- Use the Economic Calendar to know event timing and impact, and predefine what would invalidate your plan.
