Most trend indicators tell you what direction the market is heading, but they leave you on your own when it comes to deciding where to place your stop loss. The Parabolic SAR indicator for MT4 handles both. It plots a series of dots above or below each candle that simultaneously show you the trend direction and provide a dynamic trailing stop level. When the dots flip from one side of price to the other, you’ve got a clear reversal signal.
J. Welles Wilder introduced the Parabolic SAR in his 1978 book New Concepts in Technical Trading Systems – the same book that gave us RSI and ATR. The “SAR” stands for “Stop and Reverse,” which describes exactly how Wilder intended it to be used: you’re always in the market, either long or short, and the dot flip is your signal to close one position and open the opposite. In practice, most traders today use it more selectively than that, but the underlying logic remains sound.
In this review, I’ll cover the best psar mt4 settings for different trading styles, show you a specific trailing stop strategy, and explain where this indicator shines and where it falls flat.
What is the Parabolic SAR Indicator?
The Parabolic SAR calculates a trailing price point that accelerates toward the current price as a trend matures. The formula uses two variables: the Step (also called acceleration factor) and the Maximum acceleration. With the default settings, the indicator starts with a Step of 0.02 and increases by 0.02 each time price makes a new extreme in the trend direction, capping out at the Maximum of 0.20.
What this creates visually is a trail of dots that gradually curves toward the price – hence “parabolic.” Early in a trend, the dots sit far from the candles, giving the trade room to breathe. As the trend continues and the acceleration factor increases, the dots tighten closer to price. Eventually, price touches the dot level, and the system flips – dots jump to the opposite side and the process starts fresh.
The beauty of this design is that it has a built-in exit mechanism. Unlike a Moving Average which can flatline during consolidation and leave you guessing, the Parabolic SAR is always moving toward price. Every trend eventually ends, and the SAR will catch it.
How Parabolic SAR Works on MT4
When you apply the parabolic sar indicator mt4 to your chart, you’ll see small dots appearing either above or below each price candle. The interpretation is straightforward:
- Dots below price = Uptrend (bullish bias)
- Dots above price = Downtrend (bearish bias)
- Dots flip position = Potential trend reversal
During a strong uptrend, you’ll see the dots forming a rising curve beneath the candles. The gap between the dots and price narrows as the trend ages. When a bearish candle finally pushes down far enough to touch or breach the dot level, the indicator reverses – the next dot appears above the candle, signalling the start of a potential downtrend.
One thing I want to be upfront about: the SAR flips often in choppy markets. If price is grinding sideways in a 40-pip range, you’ll see the dots whipsawing above and below like a broken traffic light. This is the indicator’s biggest weakness, and it’s why I never trade PSAR signals without a trend filter – something like the ADX Indicator MT4 set above 20 does the job well.
Key Features
- Non-repainting: Once a candle closes, the SAR dot position for that bar is permanent
- Built into MT4 by default – no custom file or download required for the standard version
- Visual simplicity: dots above or below price make the signal instantly readable
- Functions as both a trend direction indicator and a trailing stop level
- Only two parameters to configure (Step and Maximum), keeping optimization simple
- Works on all timeframes and currency pairs available in MT4
Best Settings for Parabolic SAR Indicator
The default settings Wilder recommended work well as a starting point, but different trading styles benefit from adjustments:
| Parameter | Scalping (M5-M15) | Day Trading (M30-H1) | Swing Trading (H4-D1) |
|---|---|---|---|
| Step | 0.03 | 0.02 | 0.01 |
| Maximum | 0.30 | 0.20 | 0.10 |
| Effect | Tighter dots, faster flips | Balanced sensitivity | Wider stops, fewer reversals |
Higher Step values make the dots accelerate faster toward price. This means tighter trailing stops and quicker reversal signals – useful for scalpers who need fast exits, but generates more whipsaws.
Lower Step values keep the dots further from price for longer. The trailing stop is wider, which means you stay in winning trades longer but also give back more profit when the trend does reverse.
Recommended starting point: Stick with the defaults (0.02/0.2) on the H1 chart. Trade it for a few weeks, then adjust. If you’re getting stopped out of good trades too early, drop the Step to 0.015. If you’re giving back too much profit before the flip, bump it to 0.025.
Pros and Cons
| Pros | Cons |
|---|---|
| Provides a clear, visual trailing stop level at every candle | Generates excessive false signals in ranging/sideways markets |
| Extremely simple to read – no ambiguity in signal direction | Always in the market by design, which doesn’t suit most trading plans |
| Non-repainting and consistent across all timeframes | Only two parameters means limited fine-tuning compared to other indicators |
| Excellent exit tool even if you use a different indicator for entries | The acceleration function can tighten stops too aggressively in volatile conditions |
How to Install Parabolic SAR Indicator on MT4
The Parabolic SAR is built into MetaTrader 4 out of the box. No file download needed for the standard version.
Step 1: Open your MT4 terminal and navigate to the chart you want to trade.
Step 2: Click Insert in the top menu bar, then go to Indicators > Trend > Parabolic SAR.
Step 3: In the parameters window, set your Step (default 0.02) and Maximum (default 0.2). Under the “Colors” tab, choose a dot style and color that contrasts well against your chart – I use lime green dots on a black background.
Step 4: Click OK. Dots will immediately appear above or below each candle on your chart.
Step 5: To modify the settings later, double-click any dot on the chart, or right-click the indicator name in the data window and select “Properties.”
Tip: Save your configured chart as a template (right-click chart > Template > Save Template) so you can apply your PSAR setup to other pairs instantly.

Trading Strategy Using Parabolic SAR Indicator
Here’s a trend-following strategy that uses PSAR as a trailing stop tool with an EMA filter for direction. This works best on H1 and H4 charts.
Setup: Apply Parabolic SAR (Step 0.02, Maximum 0.2) and a 50 EMA to your chart.
Buy Signal:
1. Price is trading above the 50 EMA (confirming bullish bias)
2. PSAR dots flip from above price to below price
3. Enter long at the close of the candle that triggered the flip
4. Place your stop loss at the current SAR dot level
Sell Signal:
1. Price is trading below the 50 EMA (confirming bearish bias)
2. PSAR dots flip from below price to above price
3. Enter short at the close of the candle that triggered the flip
4. Place your stop loss at the current SAR dot level
Trailing Stop Management:
– At each candle close, move your stop loss to the current SAR dot level
– The SAR naturally tightens as the trend matures, locking in progressively more profit
– Exit when price finally hits the trailing SAR level, or when dots flip against your position
Take Profit: Let the SAR trail handle the exit. Alternatively, target a fixed 1:2 risk-reward ratio based on your initial stop distance.
The 50 EMA filter eliminates roughly half the false signals you’d get trading every SAR flip. You’re only taking long signals when the broader trend is up and short signals when it’s down. It’s a simple filter, but it makes a measurable difference in your win rate.
Parabolic SAR vs Moving Average
Both are trend-following tools, but they solve different problems:
| Feature | Parabolic SAR | Moving Average |
|---|---|---|
| Primary Use | Trailing stops and reversal signals | Trend direction and dynamic support/resistance |
| Signal Type | Dot flip (above/below price) | Price crossover or MA crossover |
| Exit Mechanism | Built-in via dot level | Requires separate exit rules |
| Best Market | Strong trending markets | Trending markets (smoother signals) |
| Ranging Performance | Poor – frequent whipsaws | Poor – flat line, false crossovers |
| Visual Clarity | High – dots are unambiguous | Moderate – crossover timing can be subjective |
Verdict: Use the Moving Average when you need a directional bias filter and dynamic support/resistance levels. Use the Parabolic SAR when you need a mechanical trailing stop and clear reversal signals. The strongest setup combines both – MA for trend direction, PSAR for entries and stop management. That’s essentially what the strategy above does, and it’s one of the most reliable setups I’ve traded over the years.
Frequently Asked Questions
Is the Parabolic SAR indicator free on MT4?
Yes. The Parabolic SAR is built into every installation of MetaTrader 4 as a default trend indicator. You’ll find it under Insert > Indicators > Trend. If you want enhanced features like multi-timeframe PSAR display and reversal alerts via push notification, we offer a free custom version here on ForexOBroker.
Does the Parabolic SAR indicator repaint?
No. Once a candle closes, the SAR dot for that bar is locked in permanently. On the current unclosed candle, the dot position may update in real-time as price moves, but that’s standard behavior for any indicator working with live data. All closed-bar dots are fixed and safe for backtesting.
What are the best Parabolic SAR settings for MT4?
The defaults of Step 0.02 and Maximum 0.2 are solid for most traders on H1 and H4 charts. For faster signals on M5-M15, increase the Step to 0.03. For wider trailing stops on daily charts, drop the Step to 0.01 and the Maximum to 0.1. Avoid going below Step 0.005 or above 0.05 – the extremes produce either painfully slow signals or constant whipsaws.
Can Parabolic SAR be used as a trailing stop?
This is actually one of its strongest applications. The SAR dot value at each candle close gives you a concrete price level for your stop loss. As the trend progresses, the acceleration factor pushes the dot closer to price, automatically tightening your stop. Many professional traders use the SAR purely for stop management, even when they rely on other indicators for entries.
Why does Parabolic SAR fail in ranging markets?
The indicator assumes the market is always trending. In a sideways range, price repeatedly crosses the SAR dot level, causing the dots to flip back and forth with each minor swing. Every flip looks like a reversal signal but is actually noise. The fix is straightforward: pair PSAR with a trend strength indicator like the ADX. Only trade SAR flips when ADX reads above 20-25, which confirms a real trend is in play.
