Slow RSI: EMA-Based Momentum and Overbought Signals
Summary
The Slow Relative Strength Index (SRSI), attributed to Vitali Apirine, modifies the familiar RSI approach by first smoothing closing prices with an exponential moving average. It compares the smoothed price change with its smoothed absolute change, then maps the resulting ratio to a bounded oscillator. The document gives example settings and reference levels, and describes using the oscillator both to follow momentum and to identify potentially overbought or oversold conditions.
Its main claimed distinction is that SRSI may remain in the overbought region longer than a standard RSI during an uptrend, which can help reflect persistent momentum. The material offers a conceptual comparison but no chart evidence, systematic test, or performance statistics. It also cautions implicitly through its emphasis on trending instruments: oscillator readings can behave differently in other market conditions, and the stated levels are not established as universal trading rules.
Key ideas
- SRSI applies an exponential moving average to price before measuring directional movement.
- It normalizes net change by total absolute change and bounds the result from zero to one hundred.
- The oscillator is presented for momentum following and overbought or oversold assessment.
- In an uptrend, SRSI may stay overbought longer than conventional RSI.
- The document provides no backtest demonstrating the indicator’s effectiveness.
