Pimp Your Indicators – A Smoothed Take on RSI

94
You don’t need to reinvent the wheel to find new and effective trading tools. Often, enhancing classic indicators with a few thoughtful modifications can yield surprisingly powerful results. Here’s a simple yet effective way to upgrade the RSI and turn it into a more actionable entry signal.

The Relative Strength Index (RSI) is a widely used oscillator that ranges from 0 to 100, providing a measure of upside momentum within a given timeframe. For example, an RSI reading of 60 implies a 60% upside dominance based on recent price action. Traditionally, traders interpret levels above 70 as overbought and below 30 as oversold. However, RSI on its own isn’t reliable as a standalone entry trigger. An overbought reading doesn’t necessarily mean the market is losing strength—it simply indicates recent data reflects a strong upward move.

Smoothed RSI Approaches

To extract more useful signals, we can enhance the RSI in a couple of simple but effective ways:

1. RSI vs. RSIMA (RSI Moving Average):
One approach is to smooth the RSI itself by calculating a moving average of the RSI (call it RSIMA), and then observe the difference between the RSI and its moving average. A positive difference suggests bullish momentum; a negative one, bearish. This approach reduces some noise but can still result in a choppy indicator, as seen in the subplot of the reference chart.

2. RSI on Smoothed Price (RSI5M):
A more refined method involves smoothing the price before calculating RSI. Specifically, apply a 5-period EMA (Exponential Moving Average) to the price series, then compute the RSI on this smoothed series—let’s call it RSI5M. The key insight is to then analyze the difference between RSI5M and the standard RSI. This difference creates a smoother, more robust signal that better captures market bias.

Why It Works
In uptrends, the EMA(5) smooths out short-term fluctuations and highlights the prevailing trend more clearly than raw price data. As a result, RSI5M tends to rise faster and higher than the standard RSI. The difference between the two becomes positive in uptrends and negative in downtrends, making it a useful gauge of directional momentum. This effect is illustrated in the lower subplot of the reference chart, where the smoothed signal offers a clearer view of market regimes.
