You can combine both types of analysis to achieve your goals. When you use both fundamental and technical analysis, you can get more accurate picture of the market.
I agree with you opinion. Technical analysis is all about looking into the price movements in the economy through charts and other tools, whereas, fundamental analysis deals with knowing about the economy as a whole. Where technical analysis is relevant for short to medium term decisions, fundamental analysis is required for medium to long term trade decisions.
You have to be good at chart analysis for undertaking technical analysis in an effective way. For fundamental analysis, however, one needs to be up-to-date with the news, economic variables like inflation, GDP rate, etc. All in all, for procuring maximum returns out of forex, both technical and fundamental analysis hold a unique position.
