The Hi Lo Range Oscillator Indicator for MT4 is a powerful non-repainting oscillator designed to identify overbought and oversold market conditions with precision. By calculating previous high and low prices, the indicator generates a normalized oscillator value between 0 and 100, helping traders spot potential trend reversals early.
This makes it an excellent tool for entering trades at better prices during the beginning of a new trend.

How the Hi Lo Range Oscillator Works
The indicator appears in a separate window on your MT4 chart and includes:
- Red Signal Line – Main oscillator line
- 80 Level – Overbought zone
- 20 Level – Oversold zone
Interpretation:
- Values above 80 → Market is overbought
- Values below 20 → Market is oversold
The strategy focuses on reversals from these extreme levels.
Sell Strategy (Overbought Reversal)
- The indicator moves above the 80 level (overbought).
- The red line reverses and crosses back below 80.
- Open a Sell trade.
- Place stop loss above the previous swing high.
- Target profits near the oversold 20 level or based on your risk-reward ratio.
This setup is ideal for catching bearish reversals after extended bullish moves.
Buy Strategy (Oversold Reversal)
- The indicator moves below the 20 level (oversold).
- The red line reverses and crosses back above 20.
- Open a Buy trade.
- Place stop loss below the previous swing low.
