To avoid psychology, beginners can trade responsibly by relying on small capital. Do not force trading with a larger amount when you have not gained good knowledge. Even technical analysis itself cannot necessarily provide a level of accuracy in trading because there are many things to consider.
That's why it's very important to use small capital first to trade as a beginner. initial knowledge in trading is very important, even if it is knowledge to manage the right finances for trading allocation.
unfortunately, currently, novice traders tend to prepare a large amount of funds to start trading. and they can't wait to start trading even without better knowledge. sometimes inviting a friend who is already experienced enough will help. but in my opinion, something like that is still too hasty.
True, basically trading is an activity that involves opportunities, money and risk, if you do not act carefully and do not calculate every step you will take then most likely all your money will be lost, this is not a matter of luck but about how skilled you are in managing everything well especially in the risk section. This means as you have said that trading using small amounts is highly recommended especially for beginners, because it is certain that a beginner will not have much knowledge about the world of trading which makes them very vulnerable to making mistakes.
So for the initial step that must be considered is in terms of capital, in the sense that a beginner is only advised to trade using small capital because they are still in the learning process, and one of the reasons why bringing large capital is prohibited for a beginner is because what is feared is when they are in a loss and emotional situation then it is very possible for them to take various impulsive actions and decisions that make them not hesitate to take revenge on the market without making any consideration or analysis so that in the end they will most likely lose a lot of money in an instant.
