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 EFX 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

Start date: May 2, 2025
End date: February 18, 2026
a = 7.3030
b = -0.0011
s = 0.0439
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0011) – 1
= -33.05%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0439) – 1
= 19.19%

Top border of price channel:
Exp(Y1,055)
= Exp(a + b × X1,055 + 2 × s)
= Exp(a + b × 1,533 + 2 × s)
= Exp(7.3030 + -0.0011 × 1,533 + 2 × 0.0439)
= Exp(5.7056)
= $300.56
Bottom border of price channel:
Exp(Y1,055)
= Exp(a + b × X1,055 – 2 × s)
= Exp(a + b × 1,533 – 2 × s)
= Exp(7.3030 + -0.0011 × 1,533 – 2 × 0.0439)
= Exp(5.5301)
= $252.16
