5% Trend

The slower McClellan exponential trend that assigns 5 percent weight to the current breadth input.

Also known as5 Percent TrendSlow McClellan trend

Definitions

In plain terms

This trend reacts more slowly because each update takes one twentieth of the newest breadth value and retains nineteen twentieths of its prior state.

Technical

Given input X_t and a previously initialized state, the recurrence is T5_t = 0.05 X_t + 0.95 T5_(t-1); a McClellan-family oscillator subtracts this state from the 10% Trend.

Scope

The 10 and 5 percent constants are methodology facts; initialization, rounding, revision resolution, and missing-session behavior remain separate implementation policies.

Formula

T5_t = 0.05*X_t + 0.95*T5_(t-1)
LaTeX: T^{5}_t=0.05X_t+0.95T^{5}_{t-1}

Examples

  • If the prior state is 20 and the new input is 50, the updated 5% Trend is 21.5.

Common misconceptions

  • The 5% Trend is not a five-session simple moving average.
