What does the term 'oscillator crossover' refer to?

The term 'oscillator crossover' refers to a situation when the oscillator crosses over a defined level, typically a threshold that signifies a change in trend or momentum. In technical analysis, oscillators are tools used to measure the speed and momentum of price movements. Examples include the Relative Strength Index (RSI) and Moving Average Convergence Divergence (MACD).

A crossover often occurs when the oscillator moves from a zone indicating overbought conditions to one indicating oversold conditions, or vice versa, suggesting potential buying or selling opportunities. This can alert traders to a possible shift in momentum.

Understanding the mechanics of crossover indicates that it is not simply a movement through the midpoint or an increase in volume, but rather a significant interaction with a particular predetermined level that carries trading implications.
