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 T 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

End date: April 5, 2024
a = 0.9270
b = 0.0011
s = 0.0283
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0011) – 1
= 48.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0283) – 1
= 11.98%

Top border of price channel:
Exp(Y1,060)
= Exp(a + b × X1,060 + 2 × s)
= Exp(a + b × 1,537 + 2 × s)
= Exp(0.9270 + 0.0011 × 1,537 + 2 × 0.0283)
= Exp(2.6429)
= $14.05
Bottom border of price channel:
Exp(Y1,060)
= Exp(a + b × X1,060 – 2 × s)
= Exp(a + b × 1,537 – 2 × s)
= Exp(0.9270 + 0.0011 × 1,537 – 2 × 0.0283)
= Exp(2.5298)
= $12.55

Top border of price channel:
Exp(Y1,243)
= Exp(a + b × X1,243 + 2 × s)
= Exp(a + b × 1,803 + 2 × s)
= Exp(0.9270 + 0.0011 × 1,803 + 2 × 0.0283)
= Exp(2.9301)
= $18.73
Bottom border of price channel:
Exp(Y1,243)
= Exp(a + b × X1,243 – 2 × s)
= Exp(a + b × 1,803 – 2 × s)
= Exp(0.9270 + 0.0011 × 1,803 – 2 × 0.0283)
= Exp(2.8169)
= $16.73
