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: August 7, 2024
End date: October 17, 2025

a = 2.1442

b = 0.0004

s = 0.1083

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0004) – 1
= 13.74%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1083) – 1
= 54.20%

Top border of price channel:

Exp(Y955)
= Exp(a + b × X955 + 2 × s)
= Exp(a + b × 1,388 + 2 × s)
= Exp(2.1442 + 0.0004 × 1,388 + 2 × 0.1083)
= Exp(2.8503)
= $17.29

Bottom border of price channel:

Exp(Y955)
= Exp(a + b × X955 – 2 × s)
= Exp(a + b × 1,388 – 2 × s)
= Exp(2.1442 + 0.0004 × 1,388 – 2 × 0.1083)
= Exp(2.4172)
= $11.21

= Exp(3.0040)
= $20.17

Bottom border of price channel:

Exp(Y1,255)
