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 TRIP 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
Primary Trend
Start date: January 8, 2021
End date: November 6, 2023
a = 4.0897
b = -0.0011
s = 0.1313
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0011) – 1
= -33.32%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1313) – 1
= 69.07%

Top border of price channel:
Exp(Y178)
= Exp(a + b × X178 + 2 × s)
= Exp(a + b × 256 + 2 × s)
= Exp(4.0897 + -0.0011 × 256 + 2 × 0.1313)
= Exp(4.0680)
= $58.44
Bottom border of price channel:
Exp(Y178)
= Exp(a + b × X178 – 2 × s)
= Exp(a + b × 256 – 2 × s)
= Exp(4.0897 + -0.0011 × 256 – 2 × 0.1313)
= Exp(3.5429)
= $34.57

Top border of price channel:
Exp(Y889)
= Exp(a + b × X889 + 2 × s)
= Exp(a + b × 1,288 + 2 × s)
= Exp(4.0897 + -0.0011 × 1,288 + 2 × 0.1313)
= Exp(2.9222)
= $18.58
Bottom border of price channel:
Exp(Y889)
= Exp(a + b × X889 – 2 × s)
= Exp(a + b × 1,288 – 2 × s)
= Exp(4.0897 + -0.0011 × 1,288 – 2 × 0.1313)
= Exp(2.3970)
= $10.99
