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 BA 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

Start date: June 1, 2023
End date: December 13, 2024
a = 6.2954
b = -0.0007
s = 0.0853
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.35%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0853) – 1
= 40.65%

Top border of price channel:
Exp(Y797)
= Exp(a + b × X797 + 2 × s)
= Exp(a + b × 1,156 + 2 × s)
= Exp(6.2954 + -0.0007 × 1,156 + 2 × 0.0853)
= Exp(5.6236)
= $276.87
Bottom border of price channel:
Exp(Y797)
= Exp(a + b × X797 – 2 × s)
= Exp(a + b × 1,156 – 2 × s)
= Exp(6.2954 + -0.0007 × 1,156 – 2 × 0.0853)
= Exp(5.2824)
= $196.85
