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 FDS 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: November 6, 2024
End date: September 12, 2025
a = 7.2931
b = -0.0007
s = 0.0425
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -23.25%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0425) – 1
= 18.55%

Top border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 + 2 × s)
= Exp(a + b × 1,513 + 2 × s)
= Exp(7.2931 + -0.0007 × 1,513 + 2 × 0.0425)
= Exp(6.2815)
= $534.57
Bottom border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 – 2 × s)
= Exp(a + b × 1,513 – 2 × s)
= Exp(7.2931 + -0.0007 × 1,513 – 2 × 0.0425)
= Exp(6.1113)
= $450.94

= Exp(a + b × 1,823 + 2 × s)
= Exp(7.2931 + -0.0007 × 1,823 + 2 × 0.0425)
= Exp(6.0568)
= $426.99
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(7.2931 + -0.0007 × 1,823 – 2 × 0.0425)
= Exp(5.8866)
= $360.19
