What is ta.mom() in Pine Script?

ta.mom(source, length) returns source minus source[length]: the absolute change over length bars.

How is momentum different from rate of change?

Momentum here is a simple difference. Rate of change (ta.roc) expresses the same move as a percentage of the older value, which scales comparability across price levels.

How do I use momentum for trading signals?

Common uses include zero-line crosses, trend confirmation (momentum sign aligns with trend), and divergence analysis versus price. Always combine with risk controls.
