The answer to this question depends on several factors, including the quality of the robot's programming, the speed of the internet connection, and the market conditions at the time of the news event. Some trading robots may not be able to react quickly enough to capture the full price movement resulting from a news event. In contrast, others may be able to execute trades almost instantly and profit from the market's volatility.

It's worth noting that news trading can be risky, even for trading robots. News events can be unpredictable, and the market reaction may not always be as expected. Therefore, it's crucial to have proper risk management measures in place, such as stop-loss orders, to limit potential losses.

In summary, trading robots can be used for news trading, but their ability to react fast enough depends on several factors. Traders should thoroughly test their trading robots and ensure they have appropriate risk management measures in place before using them for news trading.
