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 10, 2024
End date: April 2, 2025
a = 4.6756
b = 0.0009
s = 0.0315
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 37.55%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0315) – 1
= 13.42%

Top border of price channel:
Exp(Y992)
= Exp(a + b × X992 + 2 × s)
= Exp(a + b × 1,441 + 2 × s)
= Exp(4.6756 + 0.0009 × 1,441 + 2 × 0.0315)
= Exp(5.9974)
= $402.39
Bottom border of price channel:
Exp(Y992)
= Exp(a + b × X992 – 2 × s)
= Exp(a + b × 1,441 – 2 × s)
= Exp(4.6756 + 0.0009 × 1,441 – 2 × 0.0315)
= Exp(5.8714)
= $354.76

Exp(Y1,237)
= Exp(a + b × X1,237 + 2 × s)
= Exp(a + b × 1,798 + 2 × s)
= Exp(4.6756 + 0.0009 × 1,798 + 2 × 0.0315)
= Exp(6.3093)
= $549.65
Bottom border of price channel:
Exp(Y1,237)
= Exp(a + b × X1,237 – 2 × s)
= Exp(a + b × 1,798 – 2 × s)
= Exp(4.6756 + 0.0009 × 1,798 – 2 × 0.0315)
= Exp(6.1833)
