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 COLB 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: March 14, 2024
End date: November 19, 2024
a = -0.8593
b = 0.0023
s = 0.0579
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0023) – 1
= 133.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0579) – 1
= 26.04%

Top border of price channel:
Exp(Y1,084)
= Exp(a + b × X1,084 + 2 × s)
= Exp(a + b × 1,576 + 2 × s)
= Exp(-0.8593 + 0.0023 × 1,576 + 2 × 0.0579)
= Exp(2.9147)
= $18.44
Bottom border of price channel:
Exp(Y1,084)
= Exp(a + b × X1,084 – 2 × s)
= Exp(a + b × 1,576 – 2 × s)
= Exp(-0.8593 + 0.0023 × 1,576 – 2 × 0.0579)
= Exp(2.6833)
= $14.63

= Exp(3.4951)
= $32.95
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
