I believe that if you will both Technical Analysis (TA) and Fundamental Analysis (FA) will be a good combination.
But for me, Technical Analysis (TA) is the main key here if you are especially active in trading like you are a day trader. Because there are times when Fundamental Analysis is bullish but in your Technical Analysis is bearish, I rather support my Technical Analysis if so.
What happens is that fundamental analysis can tell you that an asset is ready for an upward movement but it is not going to tell you exactly when that is going to happen, and we know that your timing is critical when it comes to making money in the markets, so if your technical analysis is telling you the market is not ready to go up then you need to listen to it, but you should always keep your eyes open so you are ready to get in the market as soon as both your FA and TA agree and give you a buying signal.
