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 TKR 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: April 1, 2025
End date: January 5, 2026
a = 2.7036
b = 0.0010
s = 0.0490
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0010) – 1
= 41.59%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0490) – 1
= 21.63%

Top border of price channel:
Exp(Y1,063)
= Exp(a + b × X1,063 + 2 × s)
= Exp(a + b × 1,546 + 2 × s)
= Exp(2.7036 + 0.0010 × 1,546 + 2 × 0.0490)
= Exp(4.2743)
= $71.83
Bottom border of price channel:
Exp(Y1,063)
= Exp(a + b × X1,063 – 2 × s)
= Exp(a + b × 1,546 – 2 × s)
= Exp(2.7036 + 0.0010 × 1,546 – 2 × 0.0490)
= Exp(4.0785)
= $59.06

= Exp(2.7036 + 0.0010 × 1,825 + 2 × 0.0490)
= Exp(4.5402)
= $93.70
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(2.7036 + 0.0010 × 1,825 – 2 × 0.0490)
= Exp(4.3443)
