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 TGI 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 2, 2023
End date: August 6, 2024

a = -0.6673

b = 0.0021

s = 0.1579

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0021) – 1
= 112.54%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1579) – 1
= 88.08%

August 2, 2023 calculations

Top border of price channel:

Exp(Y929)
= Exp(a + b × X929 + 2 × s)
= Exp(a + b × 1,351 + 2 × s)
= Exp(-0.6673 + 0.0021 × 1,351 + 2 × 0.1579)
= Exp(2.4391)
= $11.46

Bottom border of price channel:

Exp(Y929)
= Exp(a + b × X929 – 2 × s)
= Exp(a + b × 1,351 – 2 × s)
= Exp(-0.6673 + 0.0021 × 1,351 – 2 × 0.1579)
= Exp(1.8075)
= $6.09

August 6, 2024 calculations

Top border of price channel:

Exp(Y1,183)
= Exp(a + b × X1,183 + 2 × s)
= Exp(a + b × 1,721 + 2 × s)
= Exp(-0.6673 + 0.0021 × 1,721 + 2 × 0.1579)
= Exp(3.2034)
= $24.62

Bottom border of price channel:

Exp(Y1,183)
= Exp(a + b × X1,183 – 2 × s)
= Exp(a + b × 1,721 – 2 × s)
= Exp(-0.6673 + 0.0021 × 1,721 – 2 × 0.1579)
= Exp(2.5717)
= $13.09

a = 3.1839

b = -0.0003

s = 0.0741

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0003) – 1
= -10.65%

Price channel spread:

Exp(4 × s) – 1
