I agree with you, the possibility of addiction in trading is very low, because there is no material to get addicted to trading, trading runs on the power of skill, so if you work with emotion here, you will not get anything but loss as a result. You have to learn more from the loss in trading, and you have to avoid making that mistake in the next trade, this is the main point of trading. And if we want to talk about addiction, then in that case addiction is the only place where people can achieve big wins without any kind of knowledge, skill, research, that means gambling, but there the possibility of getting big wins is 10%, and the possibility of losing is 90%, and this is why people are addicted to gambling most of the time, but trading is not an addictive thing.
A trader can be addicted to trading, There are also factors that make a trader to be addicted to trading, for example emotions, greed, invalidate or poor decision making and so on. But People hardly get addicted to trading not unlike gambling. And this is due to some procedures or steps that are followed before you could start trading for example being knowledgeable about the basics of trading, commitment, discipline, patient, consistency, and proper management and so on. Those are the factors that contribute greatly to a successful trading and also make someone to be a responsible trader. When a trader set a positive mindset and clear goals nothing will ever stop him from moving forward.
Yes, there can be addiction in trading too, addiction is something that can happen to anyone, but in trading where everything depends on luck, if someone thinks completely unrealistically, only then can he get addicted to trading. But such a case is very rare that someone gets addicted to trading, however, as a trader you always have to be realistic, here the whole thing depends on your skills, the more perfect you can trade here, the more profit you can make, in short, here you will get results depending on the strength of your skills. emotions, greed, and addiction will only bring losses here, nothing else.
