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 21, 2024
End date: February 18, 2025
a = 9.5891
b = -0.0025
s = 0.0493
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0025) – 1
= -59.62%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0493) – 1
= 21.80%

Top border of price channel:
Exp(Y1,122)
= Exp(a + b × X1,122 + 2 × s)
= Exp(a + b × 1,629 + 2 × s)
= Exp(9.5891 + -0.0025 × 1,629 + 2 × 0.0493)
= Exp(5.6407)
= $281.66
Bottom border of price channel:
Exp(Y1,122)
= Exp(a + b × X1,122 – 2 × s)
= Exp(a + b × 1,629 – 2 × s)
= Exp(9.5891 + -0.0025 × 1,629 – 2 × 0.0493)
= Exp(5.4435)
= $231.25

Top border of price channel:
Exp(Y1,244)
= Exp(a + b × X1,244 + 2 × s)
= Exp(a + b × 1,810 + 2 × s)
= Exp(9.5891 + -0.0025 × 1,810 + 2 × 0.0493)
= Exp(5.1911)
= $179.66
Bottom border of price channel:
Exp(Y1,244)
= Exp(a + b × X1,244 – 2 × s)
= Exp(a + b × 1,810 – 2 × s)
= Exp(9.5891 + -0.0025 × 1,810 – 2 × 0.0493)
= Exp(4.9938)
= $147.50
