Relative Strength Comparison (RSC) Indicator Signals
Jun 11, 2019

The Relative Strength Comparison (RSC) Indicator Signals tool measures the performance of a financial instrument relative to a benchmark symbol to identify periods of outperformance and underperformance. By comparing price changes over a specific period and smoothing the results with a moving average, it provides clear bullish and bearish signals based on trend momentum.
Usage
The indicator can be used to identify trend shifts in relative strength. When the RSC line crosses above its simple moving average (SMA), it signals a bullish shift, suggesting the primary symbol is gaining strength relative to the benchmark. Conversely, a cross below the SMA indicates a bearish shift.
Examples of use cases include:
- Trend Confirmation: Using the zero-line crossovers to confirm if a symbol is currently performing better (above 0) or worse (below 0) than the selected index.
- Momentum Shifts: Monitoring the relationship between the RSC line and the SMA to anticipate early changes in relative momentum before they are reflected in the price action alone.
Details
The script calculates the Comparative Relative Strength (CRS) by dividing the price change of the current symbol by the price change of a comparison symbol (e.g., SPX500) over a user-defined period. The formula subtracts 1 to center the baseline around zero.
- CRS Calculation:
((Symbol Close / Symbol Close [n]) / (Benchmark Close / Benchmark Close [n]) - 1.0) - Smoothing: A Simple Moving Average (SMA) is applied to the CRS values to filter out minor fluctuations and provide a signal line for trend identification.
- Visuals: The indicator features dynamic coloring where the plots and fills change based on whether the current relative strength is above or below the moving average.
Settings
- Comparison Index: The symbol used as the benchmark for the relative strength calculation (e.g., SPY, BTC, or Gold).
- Comparison Period: The lookback period used to calculate the percentage change for both the main symbol and the benchmark.
- Moving Average Period: The length of the SMA applied to the RSC line used for generating signal crossovers.
FAQ
How do I interpret the zero line?
The zero line represents parity with the benchmark. When the RSC line is above zero, the asset is outperforming the benchmark over the selected period; when below zero, it is underperforming.
What are the primary signals provided?
The primary signals are crossovers between the RSC line and its Moving Average. A crossover up is typically viewed as a buy/bullish signal, while a crossunder is viewed as a sell/bearish signal.
