Market structure is the enduring shape of a market through multiple cycles (major trends).
This particular structure was formed by bottoms in the first major bull trend of ZEC in 07/17 and 09/17.
It was then reinforced through tops in the first major bear trend of ZEC in 06/19 and 08/20 forming a two-year accumulation zone.
It has now been used as bottoms again in 05 /21, 06/21, and 07/21.
It has been revisited as a bottom now 01 /22.
