Stochastic Oscillator. Used to compare a stock's closing price to its price range over a set period of time, often 14 days. It's best used to identify short-term price movements in choppy or sideways markets.
Moving Average Convergence Divergence (MACD). Although prone to false signals in flat markets, it can be a strong indicator of bearish and bullish momentum. It uses two moving averages and the difference between them to accomplish this.
Commodity Channel Index (CCI). CCI looks at the current price and the average price over a period to show how far the price has deviated from the mean. It can signal both reversals and breakouts.
Rate of Change (ROC). ROC measures the percentage change in price over hours, days, or weeks. This oscillator is effective at spotting momentum shifts and divergences.
Money Flow Index (MFI). This oscillator looks at stock prices and volume together to determine the trading pressure by comparing buying to selling. It's useful during volume spikes or before a breakout. MFI moving opposite to price can be an early warning sign of divergence.
