FinTracker is a technical indicator that enhances the Traders Dynamic Index (TDI) by integrating advanced pattern recognition to identify rapid market reversals. It applies custom Bollinger-style volatility bands to a 10-period RSI, detecting key signals such as "Shark Fin" spikes—where the RSI breaks out of and quickly re-enters volatility bands—and "Extreme Cross" events, which are RSI crossovers occurring at overbought or oversold levels (above 68 or below 32). The indicator includes multi-layer filtering options, such as band slope and Market Base Line (MBL) crosses, to reduce noise and improve signal quality. Real-time alerts are provided via chart arrows, console logs, and optional pop-up notifications. For effective use, it is recommended to align signals with higher time frame trends, use the MBL as a momentum confirmation tool, consider volatility band expansion for reliability, and validate signals with divergence analysis. Risk management guidelines suggest placing stop losses beyond recent swing highs or lows and targeting a minimum risk-to-reward ratio of 1:2. FinTracker supports spotting key reversal points through momentum and volatility analysis, aiding traders in timing entries within the context of market structure.
