If there was big news when the news release should be wary or not OP.Based on experience is usually devastating news technical analysis.Moreover, if the news about interest rates was released, never to the OP as it is not necessarily the price moves.Therefore, in general we also need to learn fundamental analysis. Trader with small amount of investment should not trade while important news publish. Because I see that as soon as the news publishes the market fluctuates much go more high go more down within minute. So that time to understand the impact of the news is very tough. And for opening wrong position a small investor may lose his all money within short time.
