Both are important to become profitable forex traders. Technical analysis helps traders to analyse charts and figure out trends and patterns, which are necessary to place trades. And with fundamental analysis, traders analyse news that can affect the future of the market. Short-term traders, like scalpers, rely more on technical analysis because they have to close trades quickly. A combination of fundamental and technical gives the best results for long term traders who trade from weeks to months to years.
When we are doing our trading we will have to understand that using Technical Analysis is better for us as it will help us in earning the required amounts of profits from doing our trades.
