The indicators are a set of rules that traders can use to predict the price movements of a financial instrument. There are many different types of indicators, but there is no one indicator that is best for all scenarios.
There are three main types of indicators: trend following, oscillator, and volume.
Trend following indicators measure the strength and direction of the trend in order to provide signals about future price movements. They include moving averages, MACD and RSI. Oscillator indicators measure the current price relative to past prices in order to identify overbought or oversold conditions. Volume-based indicators look at trading volume in order to identify changes in market sentiment or investor interest.
