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 EIX 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 26, 2024
End date: August 1, 2025
a = 6.7751
b = -0.0017
s = 0.0996
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0017) – 1
= -45.37%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0996) – 1
= 48.97%

Top border of price channel:
Exp(Y959)
= Exp(a + b × X959 + 2 × s)
= Exp(a + b × 1,394 + 2 × s)
= Exp(6.7751 + -0.0017 × 1,394 + 2 × 0.0996)
= Exp(4.6655)
= $106.21
Bottom border of price channel:
Exp(Y959)
= Exp(a + b × X959 – 2 × s)
= Exp(a + b × 1,394 – 2 × s)
= Exp(6.7751 + -0.0017 × 1,394 – 2 × 0.0996)
= Exp(4.2669)
= $71.30
