Forex oscillators are a type of technical indicator that can help you identify when a currency pair is overbought or oversold. They can also signal when a trend is about to reverse. Oscillators work by comparing the current price with past prices. When the current price is higher than the past price, it indicates that the currency pair is overbought and may soon start to fall. Conversely, if the current price is lower than the past price, it indicates that the currency pair is oversold and may soon start to rise. Forex oscillators can be used on any time frame, but they are most commonly used on shorter time frames such as the 15-minute, 30-minute, and 1-hour chart.
