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 HTLD 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 18, 2022
End date: September 12, 2025

a = 3.3846

b = -0.0007

s = 0.0789

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0007) – 1
= -21.75%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0789) – 1
= 37.11%

Top border of price channel:

Exp(Y551)
= Exp(a + b × X551 + 2 × s)
= Exp(a + b × 795 + 2 × s)
= Exp(3.3846 + -0.0007 × 795 + 2 × 0.0789)
= Exp(3.0082)
= $20.25

Bottom border of price channel:

Exp(Y551)
= Exp(a + b × X551 – 2 × s)
= Exp(a + b × 795 – 2 × s)
= Exp(3.3846 + -0.0007 × 795 – 2 × 0.0789)
= Exp(2.6926)
= $14.77

Top border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,824 + 2 × s)
= Exp(3.3846 + -0.0007 × 1,824 + 2 × 0.0789)
= Exp(2.3167)
= $10.14

Bottom border of price channel:

Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(3.3846 + -0.0007 × 1,824 – 2 × 0.0789)
= Exp(2.0011)
= $7.40
