Forex traders use a variety of trading strategies based on technical and fundamental analysis. Technical trading is becoming more and more popular these days, and traders are using a variety of technical indicators such as trend lines, support and resistance levels, and many other methods to identify short- to medium-term trading opportunities. Some traders choose to use fundamental analysis, which revolves around interpreting economic information, including: news, government reports, and sometimes even rumors. However, it is often factors other than technical and fundamental analysis that have the most significant impact on currency prices, including events such as central bank intervention, interest rate changes, political changes, and even war.
