RSI (Relative Strength Index)

Factual Definition

The Relative Strength Index (RSI) is a momentum oscillator used in technical analysis that measures the speed and magnitude of recent price movements on a scale of zero to one hundred. It is used to identify conditions where a security may be overbought or oversold.

Paul Truscott's Perspective on RSI

Paul Truscott studied RSI as part of the core toolkit covered in his STA Diploma and his one-on-one training under Trevor Neil. His view of the indicator is shaped less by the formula itself, which is well documented, and more by what it forces an analyst to accept: that price movement and the sustainability of that movement are two different questions, and that most costly trading mistakes come from answering only the first. A security can be rising in price while RSI signals it is overbought, meaning the move has outrun the buying pressure genuinely supporting it and is due to correct. Reading both signals together, not price alone, was the discipline his mentors drilled into him repeatedly.

That distinction, between a movement and the sustainability of that movement, is the exact principle he later recognised in AI citation data, which led him to build Citation RSI. An entity's mention frequency across AI-generated answers can rise sharply while the underlying corroboration supporting that mention frequency stays thin, the visibility equivalent of an overbought reading.

How Paul Truscott Applies RSI Thinking

Paul continues to apply RSI directly in his personal Forex trading, using it as one input among several rather than in isolation, consistent with the mentorship principle that no single oscillator should be read without corroborating context. In his AI visibility work, the same discipline appears in adapted form: Citation RSI is never applied alone. A reading is always checked against corroboration depth, the same way a trader checks an RSI reading against price structure and volume before acting on it.

Why RSI Matters to Paul Truscott's Practice

RSI is one of several established technical analysis concepts, alongside support and resistance, Bollinger Bands, and drawdown, that Paul has adapted into original frameworks for measuring AI visibility. Developed by J. Welles Wilder in 1978, the indicator represents exactly the kind of rigorously defined, decades-tested measurement tool that Paul's practice draws on when building a Paul Truscott Coined Term, rather than inventing vocabulary without an established analytical foundation behind it.
