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 RCUS 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 31, 2025
End date: February 4, 2026

a = -4.7482

b = 0.0044

s = 0.1373

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0044) – 1
= 395.52%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1373) – 1
= 73.19%

Top border of price channel:

Exp(Y1,040)
= Exp(a + b × X1,040 + 2 × s)
= Exp(a + b × 1,512 + 2 × s)
= Exp(-4.7482 + 0.0044 × 1,512 + 2 × 0.1373)
= Exp(2.1562)
= $8.64

Bottom border of price channel:

Exp(Y1,040)
= Exp(a + b × X1,040 – 2 × s)
= Exp(a + b × 1,512 – 2 × s)
