Intermediate Formula defined 1 linked topicEvidence-reviewed

Definitions

In plain terms

Each new value blends the latest raw force with the prior smoothed Force Index.

Technical

With alpha=2/(13+1), FI_t = alpha×RawForce_t + (1-alpha)×FI_(t-1) after the seed.

Scope

Changing alpha or using a different moving average changes both lag and scale.

Formula

FI_t = alpha RawForce_t + (1-alpha) FI_(t-1)
LaTeX: FI_t = \alpha RawForce_t + (1-\alpha)FI_{t-1}
