Hello yong821209. Thank you for your good review. In this lecture, I tried to easily explain the core of algorithmic trading. Rather than using complex statistics, I organized the lecture using only technical indicators that are relatively easy to understand. Technical indicators are tools that have been used and verified in the trading field for a long time. If you study more indicators than the indicators mentioned in the lecture, you will be able to achieve good results. I wish yong821209 success. Thank you.
