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 27, 2024
End date: January 15, 2025
a = 10.6880
b = -0.0031
s = 0.0442
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0031) – 1
= -67.33%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0442) – 1
= 19.33%

Top border of price channel:
Exp(Y1,153)
= Exp(a + b × X1,153 + 2 × s)
= Exp(a + b × 1,673 + 2 × s)
= Exp(10.6880 + -0.0031 × 1,673 + 2 × 0.0442)
= Exp(5.6491)
= $284.03
Bottom border of price channel:
Exp(Y1,153)
= Exp(a + b × X1,153 – 2 × s)
= Exp(a + b × 1,673 – 2 × s)
= Exp(10.6880 + -0.0031 × 1,673 – 2 × 0.0442)
= Exp(5.4724)
= $238.03
