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 TFX 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 23, 2024
End date: April 2, 2025
a = 10.0289
b = -0.0028
s = 0.0599
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0028) – 1
= -63.88%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0599) – 1
= 27.08%

Top border of price channel:
Exp(Y1,104)
= Exp(a + b × X1,104 + 2 × s)
= Exp(a + b × 1,603 + 2 × s)
= Exp(10.0289 + -0.0028 × 1,603 + 2 × 0.0599)
= Exp(5.6769)
= $292.04
Bottom border of price channel:
Exp(Y1,104)
= Exp(a + b × X1,104 – 2 × s)
= Exp(a + b × 1,603 – 2 × s)
= Exp(10.0289 + -0.0028 × 1,603 – 2 × 0.0599)
= Exp(5.4373)
= $229.81

= Exp(5.0576)
= $157.21
Bottom border of price channel:
Exp(Y1,255)
