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 C 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: June 23, 2023
End date: February 20, 2026
a = 2.6725
b = 0.0011
s = 0.0851
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 50.49%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0851) – 1
= 40.57%

Top border of price channel:
Exp(Y588)
= Exp(a + b × X588 + 2 × s)
= Exp(a + b × 851 + 2 × s)
= Exp(2.6725 + 0.0011 × 851 + 2 × 0.0851)
= Exp(3.7958)
= $44.51
Bottom border of price channel:
Exp(Y588)
= Exp(a + b × X588 – 2 × s)
= Exp(a + b × 851 – 2 × s)
= Exp(2.6725 + 0.0011 × 851 – 2 × 0.0851)
= Exp(3.4552)
= $31.66
