Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of WDC price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: April 3, 2025
End date: March 2, 2026
a = -6.0015
b = 0.0065
s = 0.0670
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0065) – 1
= 964.44%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0670) – 1
= 30.71%

= $39.52
Bottom border of price channel:
Exp(Y1,014)
= Exp(a + b × X1,014 – 2 × s)
= Exp(a + b × 1,473 – 2 × s)
