OT: best wishes with your photo effort.
Techcharter's cycle length of 3.3 yrs is 10% longer than the Hurst nominal of 3 yrs. Extending that expansion to other nominals, the 9month extends to approx 43 weeks, and 21 weeks is observed as half cycle. The 13 week becomes 72 days, and the smaller structure becomes 18/36/72, which is observed.
If the goal is to trade with LT trend using the 72 day cycle, violation of the channel formed by 18 day will signal the top/bottom of the 72 day cycle. That channel was broken today, if not on yesterday's
close. Next low due in 2-3 weeks
Stay on the right side of the cycle!
