Having an understanding of a particular indior, particularly if it has been implemented as a powerful foundation for your own trading egy is important. Knowing if it's a, Leading, Lagging or momentum indior and a comprehension of it's logic will provide you with additional confidence at the indior. Also what it ought to be used for.
