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 ATR 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 26, 2022
End date: July 25, 2024

a = 3.9117

b = 0.0006

s = 0.0341

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0006) – 1
= 24.23%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0341) – 1
= 14.61%

Top border of price channel:

Exp(Y778)
= Exp(a + b × X778 + 2 × s)
= Exp(a + b × 1,127 + 2 × s)
= Exp(3.9117 + 0.0006 × 1,127 + 2 × 0.0341)
= Exp(4.6498)
= $104.56

Bottom border of price channel:

Exp(Y778)
= Exp(a + b × X778 – 2 × s)
= Exp(a + b × 1,127 – 2 × s)
= Exp(3.9117 + 0.0006 × 1,127 – 2 × 0.0341)
= Exp(4.5134)
= $91.23
