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 30, 2024
End date: August 1, 2025
a = 6.8827
b = -0.0017
s = 0.0991
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0017) – 1
= -45.76%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0991) – 1
= 48.62%

Top border of price channel:
Exp(Y993)
= Exp(a + b × X993 + 2 × s)
= Exp(a + b × 1,443 + 2 × s)
= Exp(6.8827 + -0.0017 × 1,443 + 2 × 0.0991)
= Exp(4.6625)
= $105.90
Bottom border of price channel:
Exp(Y993)
= Exp(a + b × X993 – 2 × s)
= Exp(a + b × 1,443 – 2 × s)
= Exp(6.8827 + -0.0017 × 1,443 – 2 × 0.0991)
= Exp(4.2662)
= $71.25

= Exp(a + b × 1,810 + 2 × s)
= Exp(6.8827 + -0.0017 × 1,810 + 2 × 0.0991)
= Exp(4.0474)
= $57.25
Bottom border of price channel:
Exp(Y1,245)
= Exp(a + b × X1,245 – 2 × s)
= Exp(a + b × 1,810 – 2 × s)
= Exp(6.8827 + -0.0017 × 1,810 – 2 × 0.0991)
= Exp(3.6512)
= $38.52
