RSI

Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of price movements, often used to identify overbought or oversold conditions in markets.

RSI is typically applied over a 14-day period and is scaled from 0 to 100. It does not capture fundamental market factors such as supply and demand dynamics.

How RSI Works

RSI is calculated using average gains and losses over a specified period.

  1. Average Gain: Calculate the average of upward price movements over the period.
  2. Average Loss: Calculate the average of downward price movements over the period.
  3. RSI Calculation: Use the formula RSI = 100 - (100 / (1 + RS)), where RS is the relative strength, the ratio of average gain to average loss.

Strengths and Limitations

RSI is informative for identifying potential reversal points when values cross certain thresholds, such as 30 or 70. However, it can be misleading in trending markets where prices may remain overbought or oversold for extended periods. Complementary metrics like Moving Average Convergence Divergence (MACD) can provide additional context.

RSI in Commodity Forecasting

In commodity markets, RSI is used to assess momentum in assets like oil and gold. For instance, a rising RSI in oil may indicate strengthening bullish momentum, while a declining RSI in gold could suggest weakening demand. Traders use RSI to time entry and exit points based on perceived market conditions.
