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 NPO 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: December 14, 2023
End date: November 5, 2024
a = 4.9965
b = 0.0000
s = 0.0439
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 0.82%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0439) – 1
= 19.19%

Top border of price channel:
Exp(Y1,023)
= Exp(a + b × X1,023 + 2 × s)
= Exp(a + b × 1,485 + 2 × s)
= Exp(4.9965 + 0.0000 × 1,485 + 2 × 0.0439)
= Exp(5.1175)
= $166.93
Bottom border of price channel:
Exp(Y1,023)
= Exp(a + b × X1,023 – 2 × s)
= Exp(a + b × 1,485 – 2 × s)
= Exp(4.9965 + 0.0000 × 1,485 – 2 × 0.0439)
= Exp(4.9420)
= $140.05

Top border of price channel:
Exp(Y1,247)
= Exp(a + b × X1,247 + 2 × s)
= Exp(a + b × 1,812 + 2 × s)
= Exp(4.9965 + 0.0000 × 1,812 + 2 × 0.0439)
= Exp(5.1249)
= $168.15
Bottom border of price channel:
Exp(Y1,247)
= Exp(a + b × X1,247 – 2 × s)
= Exp(a + b × 1,812 – 2 × s)
= Exp(4.9965 + 0.0000 × 1,812 – 2 × 0.0439)
= Exp(4.9493)
= $141.08
