Not only for beginners but hasty actions are also dangerous for professional traders, especially for beginners whose knowledge and experience are still very minimal.
Basically in any case, especially in activities involving money, acting hastily will always be too dangerous, because when you take hasty action, it means that your considerations are not optimal, which will lead you to the wrong decision.
On the other hand, I am sure that these actions are more often carried out by beginners, because when someone has knowledge and experience, they will certainly know that acting hastily will only endanger themselves, but beginners do not think in that direction, which is because their knowledge is still minimal, I hope they, especially beginners, look for references from various sources related to what can be done and what should be avoided.
Sometimes, even though we already have enough insight regarding trading, we are still not very skilled at controlling our emotions, which makes us always make hasty decisions. For example, sometimes we have made an analysis related to market movements. And sometimes we already know which way the market will move. Like when the support point has been penetrated then we know the next goal is a further decline. But sometimes we are not patient enough to wait for the decline. I still get stuck on this sometimes. Well, in essence, emotional management is very important in trading. And it takes a strong mentality to be patient and not be in a hurry. And yes, this happens not only to beginners but sometimes even professional traders make this mistake when their emotions are unstable and they don't take a break.
Well, that's right, I think that's definitely experienced by anyone, but I think having difficulty controlling emotions once in a while is a natural thing experienced by humans as social beings, but of course it doesn't mean that you don't need to learn to increase your insight and knowledge, because after all there is a difference in the possibility of various actions that should be avoided by a trader who does not have knowledge and a trader who has knowledge, the reason is that when you have knowledge then you will not do various actions that should be avoided too often such as emotions.
On the other hand, the scenario you told is true, I am also sometimes fooled by market situations like that when I see that the support or resistance point has been penetrated, and actually from my experience even though both points have been penetrated, it usually does not mean that the market movement will continue because it is still very possible for the price to continue to experience a reversal, so you have to be a little more patient, wait for confirmation from the next candle, don't rush to draw conclusions.
