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 TDY 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: April 4, 2024
End date: October 22, 2025
a = 5.1466
b = 0.0007
s = 0.0413
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0007) – 1
= 28.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0413) – 1
= 17.96%

Top border of price channel:
Exp(Y814)
= Exp(a + b × X814 + 2 × s)
= Exp(a + b × 1,183 + 2 × s)
= Exp(5.1466 + 0.0007 × 1,183 + 2 × 0.0413)
= Exp(6.0376)
= $418.90
Bottom border of price channel:
Exp(Y814)
= Exp(a + b × X814 – 2 × s)
= Exp(a + b × 1,183 – 2 × s)
= Exp(5.1466 + 0.0007 × 1,183 – 2 × 0.0413)
= Exp(5.8724)
= $355.11

= Exp(5.1466 + 0.0007 × 1,749 + 2 × 0.0413)
= Exp(6.4244)
= $616.74
Bottom border of price channel:
Exp(Y1,203)
= Exp(a + b × X1,203 – 2 × s)
= Exp(a + b × 1,749 – 2 × s)
