# Momentum & Oscillators

> RSI, stochastics, MACD and the full oscillator grammar, divergence included.

Momentum indicators measure the speed of price change rather than price itself: how hard buyers or sellers are pressing, and whether that pressure is building or fading. The traditional premise, useful but far from infallible, is that speed tends to fade before direction turns, so these oscillators are read both to confirm a move and to warn when it is running out of force.

The family is built around a few long lineages: RSI and its refinements, the stochastics, and MACD with its descendants, alongside plain rate-of-change measures and a long roster of standalone named oscillators. DeMark's counting studies pursue the same exhaustion points by a different route, replacing smoothed lines with rule-qualified bar counts. Across all of them runs a shared reading grammar of overbought and oversold zones, centerline behavior, and divergence.
