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 T 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 10, 2023
End date: September 23, 2025

a = 1.4224

b = 0.0011

s = 0.0428

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 51.67%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0428) – 1
= 18.69%

Top border of price channel:

Exp(Y643)
= Exp(a + b × X643 + 2 × s)
= Exp(a + b × 937 + 2 × s)
= Exp(1.4224 + 0.0011 × 937 + 2 × 0.0428)
= Exp(2.5774)
= $13.16

Bottom border of price channel:

Exp(Y643)
= Exp(a + b × X643 – 2 × s)
= Exp(a + b × 937 – 2 × s)
= Exp(1.4224 + 0.0011 × 937 – 2 × 0.0428)
= Exp(2.4061)
= $11.09

September 23, 2025 calculations

Top border of price channel:

Exp(Y1,197)
= Exp(a + b × X1,197 + 2 × s)
= Exp(a + b × 1,743 + 2 × s)
= Exp(1.4224 + 0.0011 × 1,743 + 2 × 0.0428)
= Exp(3.4973)
= $33.03

Bottom border of price channel:

Exp(Y1,197)
= Exp(a + b × X1,197 – 2 × s)
= Exp(a + b × 1,743 – 2 × s)
= Exp(1.4224 + 0.0011 × 1,743 – 2 × 0.0428)
= Exp(3.3259)
= $27.82
