According to Dow's theory, the movement is divided into three main types: main, secondary, short or daily, in cycles of all types, whether price or time. If we take the current session from the bottom of 2590, we consider a major upward trend that has not changed to the downside according to technical considerations and conditions. Main bonds Secondary bonds may extend for several months and affect the main movement and may sometimes be indicative of a change in the main direction.
