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 ORA 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: January 22, 2025
End date: September 30, 2025
a = 1.4386
b = 0.0017
s = 0.0334
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0017) – 1
= 87.01%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0334) – 1
= 14.28%

Top border of price channel:
Exp(Y1,081)
= Exp(a + b × X1,081 + 2 × s)
= Exp(a + b × 1,574 + 2 × s)
= Exp(1.4386 + 0.0017 × 1,574 + 2 × 0.0334)
= Exp(4.2048)
= $67.01
Bottom border of price channel:
Exp(Y1,081)
= Exp(a + b × X1,081 – 2 × s)
= Exp(a + b × 1,574 – 2 × s)
= Exp(1.4386 + 0.0017 × 1,574 – 2 × 0.0334)
= Exp(4.0714)
= $58.64
