Momentum indicators measure the speed of price, which often slows before a turn.
- RSI ranges from 0 to 100; Wilder recommended 14 periods. Above 70 is generally read as overbought, below 30 as oversold — zones, not orders.
- MACD = 12-period EMA minus 26-period EMA, with a 9-period signal line. Crossovers and the zero line describe momentum.
- Divergence (price makes a higher high, RSI a lower high) may warn of a trend change — “may”, not “will”.
- Indicators can stay overbought for a long time in strong trends. Use them as an extra witness, not a judge.
