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 FIX 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: April 22, 2022
End date: May 17, 2024

a = 2.5204

b = 0.0017

s = 0.0928

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0017) – 1
= 87.13%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0928) – 1
= 44.94%

Top border of price channel:

Exp(Y738)
= Exp(a + b × X738 + 2 × s)
= Exp(a + b × 1,068 + 2 × s)
= Exp(2.5204 + 0.0017 × 1,068 + 2 × 0.0928)
= Exp(4.5395)
= $93.64

Bottom border of price channel:

Exp(Y738)
= Exp(a + b × X738 – 2 × s)
= Exp(a + b × 1,068 – 2 × s)
= Exp(2.5204 + 0.0017 × 1,068 – 2 × 0.0928)
= Exp(4.1683)
= $64.61

= $342.86

Bottom border of price channel:

Exp(Y1,258)
