TDI Signal Pro is an advanced technical indicator based on the Traders Dynamic Index (TDI) methodology, integrating RSI volatility analysis with multiple signal detection systems. It combines volatility band analysis with three independent signal types: Shark Fin, Extreme Cross, and Divergence. Shark Fin signals identify overextended RSI conditions followed by momentum shifts by detecting when the RSI Price Line breaks outside and then re-enters volatility bands. Extreme Cross signals occur when the RSI crosses back inside a volatility band after being in an extreme zone, confirmed by lookback analysis. Divergence detection highlights classic RSI divergences between price and RSI movements within appropriate RSI zones to reduce noise.

The indicator projects signals directly onto the price chart as arrows with labels, dynamically scaled across timeframes from 1 minute to daily, with a history window of up to 200 bars. It supports an optional multi-timeframe RSI overlay for broader market context confirmation without changing charts. The alert system offers configurable log output, sound notifications, and on-chart popups, each independently toggleable and triggered once per closed bar.

All major features and parameters, including multi-timeframe settings, chart arrow display, band fill, signal filters, and alert options, are configurable via a structured settings panel. This tool is designed for trend and volatility analysis using RSI-based signals.
