Trading needs time, not everyone has the time to check the market prices every day, to do TA, FA, etc. Another thing is not everyone has the skills to do it, nor has patience, and may easily fall into a panic selling or to listen to the pseudo-experts we can see here and there.
Trading without these three, TA, FA, and SA, will become not profitable and useless for you because these will help you to trade effectively.
I'm not really a fan of trading before and I just want to hold my assets. But as time passes by, I'm not contented with that mindset, I want to make my assets move in the market to have some improvements and deal with the risks. Trading is really not for those people who are timid in manipulating their assets and make it grow. As I started trading, I'm becoming wiser and adaptive depending on the situation that I'm in, plus, trading will make your mindset healthier when it comes to investments. It really needs a lot of patience and practice in doing analysis techniques, don't hesitate to learn and engage with trading if you are willing to do it.
