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 DORM 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: October 18, 2023
End date: November 20, 2024
a = 2.3058
b = 0.0014
s = 0.0567
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 64.77%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0567) – 1
= 25.46%

Top border of price channel:
Exp(Y982)
= Exp(a + b × X982 + 2 × s)
= Exp(a + b × 1,427 + 2 × s)
= Exp(2.3058 + 0.0014 × 1,427 + 2 × 0.0567)
= Exp(4.3715)
= $79.16
Bottom border of price channel:
Exp(Y982)
= Exp(a + b × X982 – 2 × s)
= Exp(a + b × 1,427 – 2 × s)
= Exp(2.3058 + 0.0014 × 1,427 – 2 × 0.0567)
= Exp(4.1447)
= $63.10
