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: July 1, 2024
End date: August 12, 2025

a = 8.2337

b = -0.0022

s = 0.0786

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0022) – 1
= -54.74%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0786) – 1
= 36.93%

Top border of price channel:

Exp(Y848)
= Exp(a + b × X848 + 2 × s)
= Exp(a + b × 1,231 + 2 × s)
= Exp(8.2337 + -0.0022 × 1,231 + 2 × 0.0786)
= Exp(5.7174)
= $304.10

Bottom border of price channel:

Exp(Y848)
= Exp(a + b × X848 – 2 × s)
= Exp(a + b × 1,231 – 2 × s)
= Exp(8.2337 + -0.0022 × 1,231 – 2 × 0.0786)
= Exp(5.4030)
= $222.08

Top border of price channel:

Exp(Y1,127)
= Exp(a + b × X1,127 + 2 × s)
= Exp(a + b × 1,638 + 2 × s)
= Exp(8.2337 + -0.0022 × 1,638 + 2 × 0.0786)
= Exp(4.8335)
= $125.64

Bottom border of price channel:

Exp(Y1,127)
= Exp(a + b × X1,127 – 2 × s)
= Exp(a + b × 1,638 – 2 × s)
