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 TER 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: November 24, 2020
End date: April 24, 2024

a = 4.9753

b = -0.0002

s = 0.1330

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0002) – 1
= -8.67%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1330) – 1
= 70.26%

Top border of price channel:

Exp(Y389)
= Exp(a + b × X389 + 2 × s)
= Exp(a + b × 561 + 2 × s)
= Exp(4.9753 + -0.0002 × 561 + 2 × 0.1330)
= Exp(5.1021)
= $164.36

Bottom border of price channel:

Exp(Y389)
= Exp(a + b × X389 – 2 × s)
= Exp(a + b × 561 – 2 × s)
= Exp(4.9753 + -0.0002 × 561 – 2 × 0.1330)
= Exp(4.5699)
= $96.53

April 24, 2024 calculations

Top border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 + 2 × s)
= Exp(a + b × 1,808 + 2 × s)
= Exp(4.9753 + -0.0002 × 1,808 + 2 × 0.1330)
= Exp(4.7923)
= $120.58

Bottom border of price channel:

Exp(Y1,246)
= Exp(a + b × X1,246 – 2 × s)
= Exp(a + b × 1,808 – 2 × s)
= Exp(4.9753 + -0.0002 × 1,808 – 2 × 0.1330)
= Exp(4.2601)
= $70.82
