In technical analysis in finance, a technical indicator is a mathematical calculation based on historic price, volume, or (in the case of futures contracts) open interest information that aims to forecast financial market direction.[1] Technical indicators are a fundamental part of technical analysis and are typically plotted as a chart pattern to try to predict the market trend.[2] Indicators generally overlay on price chart data to indicate where the price is going, or whether the price is in an "overbought" condition or an "oversold" condition.
