     After many years of trading in the financial markets, the most profound insight I've gained is that "there is a significant difference between knowing and doing." This short yet profound statement reveals one of the greatest challenges traders face — the vast gap between theory and practice. This article will explore this topic, analyzing the reasons behind this gap and possible solutions.     Firstly, we need to understand why there is such a large gap between theory and practice.

Calculate True Range (TR):    - \( TR = \max(\text{Today's High ...
