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 DLR 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 23, 2022
End date: February 21, 2025

a = 3.6958

b = 0.0009

s = 0.0667

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0009) – 1
= 36.59%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0667) – 1
= 30.56%

September 23, 2022 calculations

Top border of price channel:

Exp(Y605)
= Exp(a + b × X605 + 2 × s)
= Exp(a + b × 876 + 2 × s)
= Exp(3.6958 + 0.0009 × 876 + 2 × 0.0667)
= Exp(4.5775)
= $97.27

Bottom border of price channel:

Exp(Y605)
= Exp(a + b × X605 – 2 × s)
= Exp(a + b × 876 – 2 × s)
= Exp(3.6958 + 0.0009 × 876 – 2 × 0.0667)
= Exp(4.3108)
= $74.50

February 21, 2025 calculations

Top border of price channel:

Exp(Y1,209)
= Exp(a + b × X1,209 + 2 × s)
= Exp(a + b × 1,758 + 2 × s)
= Exp(3.6958 + 0.0009 × 1,758 + 2 × 0.0667)
= Exp(5.3309)
= $206.62

Bottom border of price channel:

Exp(Y1,209)
= Exp(a + b × X1,209 – 2 × s)
= Exp(a + b × 1,758 – 2 × s)
= Exp(3.6958 + 0.0009 × 1,758 – 2 × 0.0667)
= Exp(5.0642)
= $158.26

Top border of price channel:

Exp(Y1,146)
= Exp(a + b × X1,146 + 2 × s)
= Exp(a + b × 1,663 + 2 × s)
= Exp(8.7174 + -0.0021 × 1,663 + 2 × 0.0303)
= Exp(5.3242)
= $205.25

Bottom border of price channel:
