About the Relative Strength Oscillator RSO Indicator
The Relative Strength Oscillator RSO Indicator for MT4 is an advanced momentum tool that reimagines the traditional RSI by centering its values around a zero line.
This structural change creates a symmetrical view of market strength, making it easier to compare bullish and bearish intensity.
The indicator utilizes specific levels at plus/minus 20 and plus/minus 50 to define overbought and oversold thresholds.
While the 20 levels mark standard exhaustion points, the 50 levels highlight extreme market extensions.
The RSO includes colored histograms where lime bars represent rising momentum and red bars indicate a decline.
By focusing on how the dodger blue curve interacts with these boundaries, traders can identify high-probability reversal points.
This oscillator is particularly effective for those who find standard indices difficult to read, as it provides a clearer visual representation of when a trend is likely to shift direction.

RSO Indicator + Forex Trend Filter MT4 Day Trading Strategy
This day trading method uses the Relative Strength Oscillator (RSO) together with the Forex Trend Filter MT4 Indicator.
The RSO histogram gives simple directional signals.
When the histogram is above zero, it suggests buyers are in control. When it drops below zero, it signals selling pressure.
The Trend Filter shows broader trend direction using blue bars for buy trend and red bars for sell trend.
When both indicators share the same direction, day traders get clear and structured setups that avoid unnecessary noise.
This strategy works well on M15, M30, and H1 charts.
It suits day traders who prefer stable setups rather than constant scalping.
It works best on liquid currency pairs such as CADJPY, NZDUSD, EURGBP, and AUDCAD.
These pairs provide steady intraday movement and enough volatility for clean signals while maintaining manageable spreads.
Buy Entry Rules
- The Trend Filter must show blue bars to confirm a bullish environment.
- The RSO histogram must move above the zero line to confirm upward momentum.
- Open a buy position when both conditions align.
- Place a stop loss below the most recent swing low. On M15 and M30, this is usually 8 to 15 pips. On H1, this can be 15 to 25 pips.
- Take profit at a two to one or three to one reward to risk ratio or exit when RSO begins to weaken toward the zero line.
Sell Entry Rules
- The Trend Filter must show red bars, which confirms a bearish trend.
- The RSO histogram must fall below the zero line, which confirms downward momentum.
- Open a short trade when both conditions match.
- Place a stop loss above the nearest swing high. On M15 and M30, this is typically 8 to 15 pips. On H1, this can be 15 to 25 pips.
- Target a two to one or three to one reward to risk ratio or close when RSO begins moving upward toward zero.
Advantages
- Clear directional structure because trend and momentum must agree.
- Suitable for day trading without overwhelming signal frequency.
- Reduces false signals by filtering out trades that go against the main trend.
- Works well on multiple timeframes, giving flexibility to traders.
Drawbacks
- In sideways markets, the RSO may give weak signals.
- It may require patience because good alignment does not happen constantly.
- Stop loss placement depends on volatility and may be large on H1 charts.
- May miss early reversals because confirmation requires both indicators to agree.
Case Study 1: CADJPY H1
During the Tokyo to London transition, the Trend Filter displayed steady blue bars.
The RSO histogram crossed above zero shortly after a small pullback. A long entry was triggered.
A stop loss was placed 18 pips below the swing low.
Over the next few hours, CADJPY advanced with consistent momentum.
The trade reached a 42 pip target, which was slightly more than a two-to-one reward to risk.
The position was closed when RSO began flattening, and the price slowed near resistance.
Case Study 2: NZDUSD M30
Later in the day, the Trend Filter turned red, showing bearish pressure.
The RSO histogram followed by dropping below zero, which confirmed a momentum shift.
A short entry was executed with a stop loss 12 pips above the previous swing high.
NZDUSD moved downward in a clean wave during the US morning session.
The take profit at 30 pips was reached comfortably.
The RSO began rising again afterward, so the exit was timed well.
The trade delivered close to a two and a half to one reward to risk.
Strategy Tips
- Wait for both indicators to line up in the same direction before entering a trade. This reduces noise and keeps you aligned with the dominant trend.
- Avoid trading when the RSO histogram hovers around the zero line. This often signals choppy price action with no clear direction.
- Focus on sessions with higher liquidity, such as London and New York, to get stronger and cleaner intraday swings.
- Use a fixed risk per trade to keep your day trading consistent. Position sizing is as important as the entry setup.
- When the Forex Trend Filter changes color, always reassess open trades. A color switch often warns of a weakening trend.
- On news-heavy days, wait for volatility to settle before taking new signals. Day trading works best in stable conditions.
- Look for price rejection zones, such as previous highs and lows, to validate the direction shown by the indicators.
- Use a trailing stop once the trade moves into profit to capture extended trend moves without guessing the final target.

FAQ
What do the lime and red bars signify?
Lime bars indicate that the oscillator value is increasing, showing growing momentum.
Red bars show the oscillator value is decreasing, signaling a potential slowdown or reversal.
How do I use the extreme 50 levels?
The plus/minus 50 levels represent extreme overbought or oversold conditions.
When price hits these levels, a significant correction is often imminent, making them ideal for profit-taking.
Why is the zero line important?
The zero line acts as the balance point.
Histograms staying above zero suggest a bullish market bias, while histograms staying below zero confirm a bearish sentiment.
What if the curve doesn’t reach the 20 level?
If the market is weak, the curve may not reach the 20 level.
In these cases, use a crossover of the zero center line as your secondary exit signal.
Summary
The Relative Strength Oscillator RSO Indicator provides a clear and symmetrical way to track price momentum.
Its level-based system makes identifying overextended markets straightforward for any trader.
By combining histogram colors with a central curve, it offers a high degree of clarity for entry and exit timing.
