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 GAP 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: March 10, 2023
End date: July 17, 2024

a = -1.3996

b = 0.0028

s = 0.1542

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0028) – 1
= 176.65%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1542) – 1
= 85.29%

March 10, 2023 calculations

Top border of price channel:

Exp(Y829)
= Exp(a + b × X829 + 2 × s)
= Exp(a + b × 1,205 + 2 × s)
= Exp(-1.3996 + 0.0028 × 1,205 + 2 × 0.1542)
= Exp(2.2682)
= $9.66

Bottom border of price channel:

Exp(Y829)
= Exp(a + b × X829 – 2 × s)
= Exp(a + b × 1,205 – 2 × s)
= Exp(-1.3996 + 0.0028 × 1,205 – 2 × 0.1542)
= Exp(1.6514)
= $5.21

July 17, 2024 calculations

Top border of price channel:

Exp(Y1,168)
= Exp(a + b × X1,168 + 2 × s)
= Exp(a + b × 1,700 + 2 × s)
= Exp(-1.3996 + 0.0028 × 1,700 + 2 × 0.1542)
= Exp(3.6481)
= $38.40

Bottom border of price channel:

Exp(Y1,168)
= Exp(a + b × X1,168 – 2 × s)
= Exp(a + b × 1,700 – 2 × s)
= Exp(-1.3996 + 0.0028 × 1,700 – 2 × 0.1542)
= Exp(3.0314)
= $20.73

Secondary Trend

Start date: November 20, 2023
End date: November 20, 2024

a = 2.5991

b = 0.0003

s = 0.0919

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 11.00%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0919) – 1
= 44.42%

November 20, 2023 calculations

Top border of price channel:

Exp(Y1,005)
= Exp(a + b × X1,005 + 2 × s)
= Exp(a + b × 1,460 + 2 × s)
= Exp(2.5991 + 0.0003 × 1,460 + 2 × 0.0919)
= Exp(3.2002)
= $24.54

Bottom border of price channel:

Exp(Y1,005)
= Exp(a + b × X1,005 – 2 × s)
= Exp(a + b × 1,460 – 2 × s)
= Exp(2.5991 + 0.0003 × 1,460 – 2 × 0.0919)
= Exp(2.8327)
= $16.99

November 20, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(2.5991 + 0.0003 × 1,826 + 2 × 0.0919)
= Exp(3.3049)
= $27.24

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
