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 WFRD 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: April 24, 2024
End date: November 20, 2024
a = 7.6271
b = -0.0023
s = 0.0705
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0023) – 1
= -56.35%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0705) – 1
= 32.60%

Top border of price channel:
Exp(Y831)
= Exp(a + b × X831 + 2 × s)
= Exp(a + b × 1,206 + 2 × s)
= Exp(7.6271 + -0.0023 × 1,206 + 2 × 0.0705)
= Exp(5.0290)
= $152.78
Bottom border of price channel:
Exp(Y831)
= Exp(a + b × X831 – 2 × s)
= Exp(a + b × 1,206 – 2 × s)
= Exp(7.6271 + -0.0023 × 1,206 – 2 × 0.0705)
= Exp(4.7469)
= $115.22

= Exp(4.5521)
= $94.83
Bottom border of price channel:
Exp(Y977)
= Exp(a + b × X977 – 2 × s)
= Exp(a + b × 1,416 – 2 × s)
= Exp(7.6271 + -0.0023 × 1,416 – 2 × 0.0705)
= Exp(4.2699)
