Reverse Engineering RSI Thresholds into Price Bands

Article MQL5 code base

Summary

The document presents a chart indicator that algebraically reverses the Relative Strength Index calculation to estimate the price at which RSI would reach chosen overbought or oversold levels. Instead of waiting for the oscillator to reach a threshold in a separate panel, a trader can view corresponding price levels on the main chart. The stated applications include anticipating possible market extremes, placing limit orders, and treating the levels as dynamic support or resistance.

The described implementation accounts for Wilder’s recursive smoothing and uses the prior bar’s verified state to calculate the current bar’s required price. It claims to match MetaTrader 5’s standard RSI and to avoid repainting, but the document gives no derivation, parameter details, validation results, or trading evidence. RSI threshold projections remain indicator levels rather than forecasts of price direction or turning points. Their practical value depends on the selected RSI settings and market context, and the material does not explain how to manage false signals or evaluate a strategy built around the bands.

Key ideas

  • The indicator solves for the price corresponding to a selected RSI threshold and plots that level on the price chart.
  • Its calculation is described as using Wilder smoothing and the preceding bar’s RSI state.
  • The bands may inform limit-order placement or potential support and resistance analysis.
  • The document asserts alignment with standard MetaTrader 5 RSI behavior but supplies no independent validation or performance evidence.
  • A projected RSI level does not by itself establish that price will reverse or reach that level.
