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 POST 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: August 2, 2024
End date: January 16, 2026
a = 5.0747
b = -0.0002
s = 0.0324
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -8.47%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0324) – 1
= 13.85%

Top border of price channel:
Exp(Y889)
= Exp(a + b × X889 + 2 × s)
= Exp(a + b × 1,290 + 2 × s)
= Exp(5.0747 + -0.0002 × 1,290 + 2 × 0.0324)
= Exp(4.8266)
= $124.79
Bottom border of price channel:
Exp(Y889)
= Exp(a + b × X889 – 2 × s)
= Exp(a + b × 1,290 – 2 × s)
= Exp(5.0747 + -0.0002 × 1,290 – 2 × 0.0324)
= Exp(4.6969)
= $109.61
