Just to be more precise. It should report the date of the lowest/highest point of a certain market during its entire history. During the year, seasonally, when the Dax (or any other market) hits the bottom and when it hits the top?
If I plotted the ind correctly, it results in a higher/ lower band. What I a am really looking for is the seasonal high and low during a calendar year calculated over the whole data base.
Here is what I can do for seasonal indicator. Seems quite similar as your example, this one have been calculated from 2000 to 2016, since I don’t know from how many years yours has been computed, I don’t know if the little noticeable differences come from that.
Is your request has something to deal with the pathfinder trading strategy seasonality factor? I think this indicator could be of interest of members who contribute to these topics.
