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 CB 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: July 23, 2025
End date: February 23, 2026
a = 4.0096
b = 0.0010
s = 0.0239
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 42.38%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0239) – 1
= 10.04%

Top border of price channel:
Exp(Y1,107)
= Exp(a + b × X1,107 + 2 × s)
= Exp(a + b × 1,610 + 2 × s)
= Exp(4.0096 + 0.0010 × 1,610 + 2 × 0.0239)
= Exp(5.6159)
= $274.77
Bottom border of price channel:
Exp(Y1,107)
= Exp(a + b × X1,107 – 2 × s)
= Exp(a + b × 1,610 – 2 × s)
= Exp(4.0096 + 0.0010 × 1,610 – 2 × 0.0239)
= Exp(5.5202)
= $249.69
