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 COHR 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 16, 2023
End date: November 19, 2024
a = -0.1157
b = 0.0026
s = 0.1084
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0026) – 1
= 157.01%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1084) – 1
= 54.25%

Top border of price channel:
Exp(Y939)
= Exp(a + b × X939 + 2 × s)
= Exp(a + b × 1,365 + 2 × s)
= Exp(-0.1157 + 0.0026 × 1,365 + 2 × 0.1084)
= Exp(3.6311)
= $37.76
Bottom border of price channel:
Exp(Y939)
= Exp(a + b × X939 – 2 × s)
= Exp(a + b × 1,365 – 2 × s)
= Exp(-0.1157 + 0.0026 × 1,365 – 2 × 0.1084)
= Exp(3.1977)
= $24.48

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