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 FORM 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: September 15, 2022
End date: July 31, 2024

a = 1.7289

b = 0.0013

s = 0.0923

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0013) – 1
= 62.03%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0923) – 1
= 44.68%

September 15, 2022 calculations

Top border of price channel:

Exp(Y709)
= Exp(a + b × X709 + 2 × s)
= Exp(a + b × 1,030 + 2 × s)
= Exp(1.7289 + 0.0013 × 1,030 + 2 × 0.0923)
= Exp(3.2754)
= $26.45

Bottom border of price channel:

Exp(Y709)
= Exp(a + b × X709 – 2 × s)
= Exp(a + b × 1,030 – 2 × s)
= Exp(1.7289 + 0.0013 × 1,030 – 2 × 0.0923)
= Exp(2.9061)
= $18.29

July 31, 2024 calculations

Top border of price channel:

Exp(Y1,179)
= Exp(a + b × X1,179 + 2 × s)
= Exp(a + b × 1,715 + 2 × s)
= Exp(1.7289 + 0.0013 × 1,715 + 2 × 0.0923)
= Exp(4.1811)
= $65.44

Bottom border of price channel:

Exp(Y1,179)
= Exp(a + b × X1,179 – 2 × s)
= Exp(a + b × 1,715 – 2 × s)
= Exp(1.7289 + 0.0013 × 1,715 – 2 × 0.0923)
= Exp(3.8118)
= $45.23

Description

a = 7.5086

b = -0.0021

s = 0.0777

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0021) – 1
= -53.32%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0777) – 1
= 36.43%

May 6, 2024 calculations

Top border of price channel:

Exp(Y1,120)
= Exp(a + b × X1,120 + 2 × s)
= Exp(a + b × 1,629 + 2 × s)
= Exp(7.5086 + -0.0021 × 1,629 + 2 × 0.0777)
= Exp(4.2642)
= $71.10

Bottom border of price channel:
