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 TXN 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 10, 2025
End date: July 8, 2025
a = -2.7078
b = 0.0044
s = 0.0365
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0044) – 1
= 405.80%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0365) – 1
= 15.74%

Top border of price channel:
Exp(Y1,195)
= Exp(a + b × X1,195 + 2 × s)
= Exp(a + b × 1,736 + 2 × s)
= Exp(-2.7078 + 0.0044 × 1,736 + 2 × 0.0365)
= Exp(5.0748)
= $159.94
Bottom border of price channel:
Exp(Y1,195)
= Exp(a + b × X1,195 – 2 × s)
= Exp(a + b × 1,736 – 2 × s)
= Exp(-2.7078 + 0.0044 × 1,736 – 2 × 0.0365)
= Exp(4.9287)
= $138.20

Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
