It is at least clear that DCA is not an emotion control machine, that is, if an investor uses DCA and immediately starts thinking that his emotions will be automatically controlled, then this is a completely wrong idea. It is very important to create a realistic framework by understanding his limitations. Initially, some investors have the idea that if they invest following the DCA strategy, they will not make any mistakes, rather, what they will do is right, but in reality this is not right because if an investor does not consider his income, expenses, remaining money, possible urgent needs, form an emergency fund, or decide not to sell the investment due to the possible price changes, then he can sell his investment at any time. That is why discipline and management are more important than strategy. There are many investors who invest relatively large amounts of money and still they can hold their investment for years, while there are some investors who invest little by little and cannot hold it for long and suddenly they have to sell it, the only reason for which is lack of proper management. DCA is certainly an effective strategy for all types of investors, but only through proper management and long-term investment planning.
