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: February 3, 2021
End date: November 6, 2023
a = 4.0374
b = -0.0012
s = 0.1249
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -34.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1249) – 1
= 64.83%

Top border of price channel:
Exp(Y140)
= Exp(a + b × X140 + 2 × s)
= Exp(a + b × 203 + 2 × s)
= Exp(4.0374 + -0.0012 × 203 + 2 × 0.1249)
= Exp(4.0536)
= $57.60
Bottom border of price channel:
Exp(Y140)
= Exp(a + b × X140 – 2 × s)
= Exp(a + b × 203 – 2 × s)
= Exp(4.0374 + -0.0012 × 203 – 2 × 0.1249)
= Exp(3.5539)
= $34.95

Top border of price channel:
Exp(Y834)
= Exp(a + b × X834 + 2 × s)
= Exp(a + b × 1,209 + 2 × s)
= Exp(4.0374 + -0.0012 × 1,209 + 2 × 0.1249)
= Exp(2.8956)
= $18.10
Bottom border of price channel:
Exp(Y834)
= Exp(a + b × X834 – 2 × s)
= Exp(a + b × 1,209 – 2 × s)
= Exp(4.0374 + -0.0012 × 1,209 – 2 × 0.1249)
= Exp(2.3959)
= $10.98
