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 MTG 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 22, 2022
End date: December 12, 2024

a = 1.6055

b = 0.0010

s = 0.0439

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 44.86%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0439) – 1
= 19.19%

Top border of price channel:

Exp(Y560)
= Exp(a + b × X560 + 2 × s)
= Exp(a + b × 812 + 2 × s)
= Exp(1.6055 + 0.0010 × 812 + 2 × 0.0439)
= Exp(2.5177)
= $12.40

Bottom border of price channel:

Exp(Y560)
= Exp(a + b × X560 – 2 × s)
= Exp(a + b × 812 – 2 × s)
= Exp(1.6055 + 0.0010 × 812 – 2 × 0.0439)
= Exp(2.3421)
= $10.40

December 12, 2024 calculations

Top border of price channel:

Exp(Y1,119)
= Exp(a + b × X1,119 + 2 × s)
= Exp(a + b × 1,624 + 2 × s)
= Exp(1.6055 + 0.0010 × 1,624 + 2 × 0.0439)
= Exp(3.3421)
= $28.28

Bottom border of price channel:

Exp(Y1,119)
= Exp(a + b × X1,119 – 2 × s)
= Exp(a + b × 1,624 – 2 × s)
= Exp(1.6055 + 0.0010 × 1,624 – 2 × 0.0439)
= Exp(3.1665)
= $23.73

Description

  • The primary trend is increasing.
