Frequently Asked Questions

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

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.

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