Decade 5ths
Using the Gann Box with 5ths ratios over a decade of time (currently 2020-2030) and plotting a simple price range that can "grow or shrink" as price moves over time.
I typically have the current range, one larger box and one smaller range box for each cycle (decade). You can see between 2010-2020 we were at lower prices, so I was using a range of 0-1,000 and also had 0-10,000 and 0-100,000.
The current time cycle (2020-2030) has earned the price overlay of 0-1,000,000 and still keeping the smaller price ranges, 0-100k and 0-10k until they're not needed or price comes back to them.
