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 CTKB 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: May 9, 2025
End date: September 18, 2025
a = -3.6901
b = 0.0034
s = 0.0748
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0034) – 1
= 244.94%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0748) – 1
= 34.87%

Top border of price channel:
Exp(Y953)
= Exp(a + b × X953 + 2 × s)
= Exp(a + b × 1,386 + 2 × s)
= Exp(-3.6901 + 0.0034 × 1,386 + 2 × 0.0748)
= Exp(1.1613)
= $3.19
Bottom border of price channel:
Exp(Y953)
= Exp(a + b × X953 – 2 × s)
= Exp(a + b × 1,386 – 2 × s)
= Exp(-3.6901 + 0.0034 × 1,386 – 2 × 0.0748)
= Exp(0.8621)
= $2.37

Top border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 + 2 × s)
= Exp(a + b × 1,518 + 2 × s)
= Exp(-3.6901 + 0.0034 × 1,518 + 2 × 0.0748)
= Exp(1.6091)
= $5.00
Bottom border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 – 2 × s)
= Exp(a + b × 1,518 – 2 × s)
= Exp(-3.6901 + 0.0034 × 1,518 – 2 × 0.0748)
= Exp(1.3099)
= $3.71
