Apirine Slow RSI
Jun 8, 2015

The Apirine Slow RSI indicator is a momentum price oscillator designed to provide smoother trend signals and identify potential reversal points through overbought and oversold conditions. By utilizing a smoothed average of price relative to its exponential moving average, it aims to reduce noise compared to the traditional RSI, making it easier to identify sustainable momentum shifts and divergences.
Usage
The Usage section describes how the script can be used to identify market conditions and potential trade setups:
- Overbought/Oversold (OB/OS) Levels: Historically, levels above 70 indicate an overbought condition, while levels below 30 indicate an oversold condition. Traders often look for the indicator to cross back inside these levels as a potential reversal signal.
- Midline Crossovers: The 50 level acts as a momentum filter. Staying above 50 suggests bullish momentum, while staying below 50 suggests bearish momentum.
- Divergences: Bullish or bearish divergences between the price action and the Slow RSI can signal weakening momentum. Users should note that these are often more effective when confirmed by a trend tool like ADX to avoid trading against strong established trends.
Details
The Apirine Slow RSI was introduced by Vitali Apirine in the July 2015 issue of Technical Analysis of Stocks & Commodities (TASC). Unlike the standard RSI which uses price change from bar to bar, the Slow RSI calculates relative strength based on the difference between the current price and its Exponential Moving Average (EMA). This difference is then smoothed using a Wilder's Smoothing Average (Wima) to create a less volatile oscillator that remains bounded between 0 and 100.
Settings
- Smoothing: Sets the length for the EMA used in the initial price calculation. This determines the baseline from which price deviations are measured.
- RSI Length: The period used for the Wilder's Smoothing of the gains and losses. Higher values result in a smoother line with more lag.
- Source: The price data point used for calculations (default is Close).
- OB Level: Defines the upper threshold for overbought market conditions (default is 70).
- OS Level: Defines the lower threshold for oversold market conditions (default is 30).
FAQ
How do I interpret the Apirine Slow RSI?
The indicator is interpreted similarly to a standard RSI; readings above 70 suggest overbought conditions, while readings below 30 suggest oversold conditions. Crossovers of the 50 midline indicate shifts in medium-term momentum.
How does this differ from the standard RSI?
The Slow RSI uses the distance between price and an EMA rather than simple price changes. This typically results in a smoother oscillator that is less reactive to minor price fluctuations.
