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 TPH 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: July 11, 2024
End date: June 26, 2025

a = 5.7738

b = -0.0014

s = 0.0586

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0014) – 1
= -39.81%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0586) – 1
= 26.41%

Top border of price channel:

Exp(Y949)
= Exp(a + b × X949 + 2 × s)
= Exp(a + b × 1,380 + 2 × s)
= Exp(5.7738 + -0.0014 × 1,380 + 2 × 0.0586)
= Exp(3.9717)
= $53.07

Bottom border of price channel:

Exp(Y949)
= Exp(a + b × X949 – 2 × s)
= Exp(a + b × 1,380 – 2 × s)
= Exp(5.7738 + -0.0014 × 1,380 – 2 × 0.0586)
= Exp(3.7373)
= $41.99

Top border of price channel:

Exp(Y1,189)
= Exp(a + b × X1,189 + 2 × s)
= Exp(a + b × 1,730 + 2 × s)
= Exp(5.7738 + -0.0014 × 1,730 + 2 × 0.0586)
= Exp(3.4849)
= $32.62

Bottom border of price channel:

Exp(Y1,189)
= Exp(a + b × X1,189 – 2 × s)
= Exp(a + b × 1,730 – 2 × s)
= Exp(5.7738 + -0.0014 × 1,730 – 2 × 0.0586)
= Exp(3.2505)
= $25.80
