Overview
T3 is an excellent data-fitting technique by Tim Tillson (cf. ``Smoothing Techniques For More Accurate Signals'' in Technical Analysis of Stocks and Commodities - January 1998)
Calculation
N is the Exponential Moving Average Period a is the amplification percentage of the filter's response to price movement (0 < a < 1)
Close1 = N-days EMA of Close Prices
Close3 = N-days EMA of Close2
Close3 = N-days EMA of Close2
Close4 = N-days EMA of Close3
Close5 = N-days EMA of Close4
Close6 = N-days EMA of Close5
c1 = (-a)^3
c2 = 3 * a^2
c3 = - 6 * a^2 - 3 * a - 3 * a^3
c4 = 1 + 3 * a + a^3 + 3 * a^2
T3 = c1 * Close6 + c2 * Close5 + c3 * Close4 + c4 * Close3
Parameters
The default values are : N = 5 a = 0.7
Examples
GT::Indicators::T3->new() GT::Indicators::T3->new([5, 0.7])
