The Chaikin Oscillator was developed by Marc Chaikin in the 1980s and is based on the observation that volume tends to precede price movements in financial markets. The Chaikin Oscillator value oscillates above and below a zero line. Positive values indicate that the accumulation of the asset's price is increasing, while negative values indicate that distribution is increasing. The Chaikin Oscillator is often used to identify potential buy or sell signals based on divergences between the oscillator and the asset price.
