It seems to me that both technical and fundamental analysis are important. The fact is that fundamental and technical analysis of the currency or stock market do not contradict each other in any way. Moreover, they work great together, as technical analysis allows you to visually verify what is really happening in the market.
Moreover, you can combine both types of forecasting to achieve your goals. Having identified the main trend using the fundamental method, look for confirmation on the chart and this allows you to open more accurate positions for a particular trading instrument.
