The TDI (Traders Dynamic Index) is a technical analysis tool that combines several indicators to provide insights into market trends and potential trading signals. It integrates the Relative Strength Index (RSI), moving averages, and volatility bands, allowing traders to assess market momentum as well as overbought or oversold conditions. The TDI typically includes three main lines: the RSI line, a signal line, and a volatility band (or market baseline), making it effective for identifying entry and exit points in various trading strategies.
