The RSX Pro Oscillator Indicator MT4 is a refined version of the classic Relative Strength Index (RSI) that applies advanced RSX smoothing to minimize noise and enhance signal precision.
This version introduces adaptive smoothing, overbought/oversold alerts, and arrow plotting, helping traders time market reversals and trends with exceptional accuracy.
Key Features
- Adaptive Smoothing Engine

- Dynamic Overbought/Oversold Zones
- Levels are set by default at 80 (overbought) and 20 (oversold).
- Alerts you when price exits or enters these regions.
- Trend and Slope Detection
- Detects the direction of RSX slope to identify potential trend shifts.
- Provides early warnings of bullish or bearish momentum changes.
- Visual Arrow Signals
- Displays up and down arrows when entering or exiting OB/OS zones.
- Separate color and code customization for each arrow event.
- Comprehensive Alert System
- Supports alerts by message, sound, notification, or email.

alert2.wav. - Prevents duplicate alerts within the same bar.

How RSX Pro Oscillator Works
This indicator measures momentum strength and trend exhaustion using a modified RSX algorithm.
- Core Calculation:
The RSX value is derived from the selected price type (PRICE_TYPICALby default) and smoothed adaptively to filter random noise. - Slope & Trend Logic:
- Slope > 0: RSX rising → bullish pressure
- Slope < 0: RSX falling → bearish pressure
- Overbought/Oversold Logic:
- RSX > 80 → Overbought (SELL zone)
- RSX < 20 → Oversold (BUY zone)
- Zone exits trigger opposite directional signals with visual arrows.
- Arrow Plotting:
- Blue Arrow: Entering overbought/oversold zone.
- Red Arrow: Exiting zone (potential reversal).
- Arrow gap and size adjustable (
arrowsDisplaceUp,arrowsDisplaceDn).
- Alert Triggers:
- Slope change or zone crossing events trigger alerts.
- Real-time or closed-bar alert mode configurable (
alertsOnCurrent).

FAQ
Q1: What is the difference between RSI and RSX?
RSX uses a smoother calculation, reducing false spikes and lag while keeping sensitivity to momentum.
Q2: Does the RSX Pro repaint?
No. It uses confirmed bar data for plotting; once a candle closes, signals remain fixed.
Q3: Can I use it for scalping?
Yes, but lower timeframes may require adjusting Length to 5 or 6 for responsiveness.
Q4: How do I change alert sounds?
Replace alert2.wav with your own .wav file in the sounds folder and update the soundFile input.
Q5: Is it compatible with all brokers and assets?
Yes, it works with any MT4 instrument — forex, commodities, indices, or crypto.
