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 WTW 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 27, 2023
End date: March 31, 2025
a = 4.3346
b = 0.0008
s = 0.0447
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0008) – 1
= 34.76%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0447) – 1
= 19.60%

Top border of price channel:
Exp(Y835)
= Exp(a + b × X835 + 2 × s)
= Exp(a + b × 1,212 + 2 × s)
= Exp(4.3346 + 0.0008 × 1,212 + 2 × 0.0447)
= Exp(5.4146)
= $224.67
Bottom border of price channel:
Exp(Y835)
= Exp(a + b × X835 – 2 × s)
= Exp(a + b × 1,212 – 2 × s)
= Exp(4.3346 + 0.0008 × 1,212 – 2 × 0.0447)
= Exp(5.2357)
= $187.86

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(4.3346 + 0.0008 × 1,825 + 2 × 0.0447)
= Exp(5.9156)
= $370.79
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(4.3346 + 0.0008 × 1,825 – 2 × 0.0447)
= Exp(5.7367)
= $310.03
