XAUUSD (Gold) is a popular trading instrument in the forex market due to its high volatility and profit potential. However, major economic news events—such as Non-Farm Payrolls, Fed interest rate decisions, or European Central Bank announcements—can cause significant price spikes, posing risks to automated trading strategies. To manage these risks, a News Filter in an Expert Advisor (EA) can pause trading during high-impact news periods. In this article, I'll show you how to create a simple News Filter for XAUUSD trading on MT5 and share a practical code example to get you started.

Why Use a News Filter for XAUUSD Trading?

News events related to USD, GBP, or EUR often lead to sharp movements in XAUUSD prices. For example, a Fed rate hike announcement might cause gold prices to drop rapidly, triggering stop-losses or unexpected losses in an automated trading system. A News Filter helps by:

• Pausing Trading: Temporarily halting trades before and after major news events to avoid volatility.
• Reducing Risk: Protecting your account from sudden market swings.
• Improving Consistency: Ensuring your EA trades only in stable market conditions.

In the next section, I'll provide a simple MQL5 code snippet to implement a News Filter for your XAUUSD trading strategy.

Code Explanation

• Inputs: MinutesBeforeNews and MinutesAfterNews allow you to define the time window (in minutes) to pause trading before and after a news event.
• News Times: The newsTimes array contains predefined news event times (e.g., May 7, 2025, 14:30). In practice, you can replace this with a real news feed from an economic calendar API.
• Logic: The IsNewsTime() function compares the current time (TimeCurrent()) with the news event times. If the current time falls within the pause window, trading is halted.
• Usage: Integrate this filter into your EA by calling IsNewsTime() in the OnTick() function before executing any trades.
