What is the Super Trend Indicator & How Does It Work?

If you’ve ever opened a trading chart, you must have noticed those lines moving along with the price candles. They flip positions, change colours, and seem to react every time the price shifts. One of those lines is the Supertrend indicator. It indicates whether a stock is generally moving up or down at a given time. In this blog, discover everything that you need to know about the Supertrend indicator.

What is the Supertrend Indicator?

The Supertrend indicator, created by Oliver V. Seban in 2009, helps spot entry and exit points for trading. The line below the price signals an uptrend, while the line above the price signals a downtrend.

Here are its features:

A green line appears when the market is in an uptrend. It indicates a potential buying opportunity.
A red line appears when the market is in a downtrend. It signals a potential sell or exit.
Commonly used in stocks, commodities, forex, and cryptocurrencies.
It can be customised by adjusting its period and multiplier settings.

How Does the Supertrend Indicator Work?

Now that we know what a supertrend indicator does, let’s understand how it works through simple steps.

Step 1: It Measures Market Volatility

The supertrend indicator uses Average True Range (ATR) to measure market volatility. Bigger swings mean more volatility; smaller moves mean less.

Step 2: It Calculates a Dynamic Line

Along with ATR, the indicator uses a multiplier.

A multiplier, usually 2 or 3, sets how far the line is from the price. The indicator adjusts the line as the price moves above or below accordingly.

Step 3: It Follows the Price Direction

Using the ATR value and the multiplier, the indicator calculates a dynamic line that adjusts as the price moves. When the price starts to fall, the line moves above the price and turns red. When the price is rising, the line appears below and turns green.

Step 4: Signals Trend Reversal

When the price crosses the supertrend line, its position and colour flip, showing a trend reversal.

Supertrend Indicator Formula

Before diving into the supertrend indicator formula, let’s understand the two main components: ATR and the multiplier.

ATR tracks daily price moves using the high, low, and close for the past 14 days. It gauges market volatility.

ATR Formula = (Current High – Current Low) + (Current High – Previous Close) + (Previous Close – Current Low) ÷ 3

Now, let’s understand the calculation through a single formula. Let’s assume that the prices for a stock are as follows over the duration of three days:

Day	High (INR)	Low (INR)	Close (INR)
Day 1	120	110	115
Day 2	125	115	120
Day 3	130	118	125

Let’s calculate the ATR:

Range for Day 1 = INR 120 – INR 110 = INR 10

Range for Day 2 = INR 125 – INR 115 = INR 10

Range for Day 3 = INR 130 – INR 118 = INR 12

Now, we’ll add these ranges and then divide them by 3, the number of days.

So, ATR = (10 + 10 + 12) ÷ 3 = INR 10.67

The ATR that we’ve calculated here signals the average price movement. Using this, the supertrend determines the following two important lines:

Upper Band = Closing Price + (Multiplier × ATR)

Lower Band = Closing Price – (Multiplier × ATR)

Generally, the multiplier is 2. However, traders can change it. Now, let’s assume that the closing price of gold for today is INR 40,000. On the other hand, ATR is INR 200. We’ll calculate the upper and lower bands using a multiplier of 2.

Upper Band = INR 40,000 + (2 × 200) = INR 40,400

Lower Band = INR 40,000 – (2 × 200) = INR 39,600

Buy when the gold price rises above INR 40,400, as signalled by a green line. Sell or exercise caution if the price falls below INR 39,600, and the indicator shows red.

Supertrend Indicator Buy Sell Signals

The supertrend indicator shows easy-to-interpret buy and sell signals. These are mainly based on where the line appears in relation to the price and whether it changes colour. Here are two important aspects of the supertrend indicator buy-sell signals:

Buy Signal (Green Signal)

A buy signal appears when the price moves above the supertrend line, and it turns green. This indicates a possible uptrend.

Sell Signal (Red Signal)

A sell signal occurs when the price drops below the line and the indicator turns red, suggesting a possible downtrend.

How to Use the Supertrend Indicator in Trading

Supertrend is beginner-friendly. For best results, use it with confirmation tools. First, open a demat account and follow these steps:

Step 1: Add Supertrend and EMA to Your Chart

Add the Supertrend indicator to your platform. Beginners can set ATR to 10 and multiplier to 3.

Add the EMA indicator with periods like 9, 21, or 50. Remember:

A shorter EMA (9 or 21) reacts more quickly to price changes and provides faster signals.
A longer EMA (like 50) moves more smoothly and shows the bigger trend direction.

Step 2: Identify the Main Trend Using EMA

If the price is above the EMA, the trend is likely upward; below means downward. This avoids trading against the trend.

Step 3: Wait for Supertrend Confirmation

Buy when the price is above the EMA, and the Supertrend turns green. Sell when the price is below the EMA and the supertrend turns red.

Step 4: Enter and Set Stop-Loss

Enter after the candle closes. Set stop-loss near the supertrend line to manage risk.

Step 5: Exit When Trend Changes

Exit when the supertrend flips, or price crosses EMA. This helps reduce false signals.

Best Supertrend Indicator Settings

As a beginner, you should try the following combinations:

Default Setting (Best for Beginners)

ATR Period: 10

Multiplier: 3

This common combination works for most stocks and timeframes. It balances sensitivity and reliability.

For Intraday Trading

ATR Period: 7 to 10

Multiplier: 2

A lower multiplier increases sensitivity, producing quicker but potentially more false, signals for short-term trades.

For Swing or Positional Trading

ATR Period: 10 to 14

Multiplier: 3 to 4

A higher multiplier keeps the line further from the price, reducing false flips for longer trends.

Advantages of the Supertrend Indicator

Supertrend keeps trading decisions simple with clear visual signals. Benefits include:

Simple and Beginner-Friendly: One of the biggest advantages of Supertrend is its clarity. The colour change, such as green for an uptrend and red for a downtrend, helps you understand the market direction without advanced technical knowledge.

Clear Entry and Exit Signals: Supertrend gives direct buy or sell signals when the line and colour flip, indicating trend shifts.

Automatically Adjusts to Volatility: ATR-based, the indicator shifts with market conditions, reacting quickly to volatility changes.

Useful Across Timeframes and Markets: Supertrend works on all timeframes and markets, including stocks, forex, and cryptocurrencies.

Limitations of the Supertrend Indicator

While the Supertrend indicator is simple and effective, it has its limitations, such as:

Not Reliable in Sideways Markets: Supertrend works best in trending markets, not sideways ones. Frequent line crossings in sideways markets can lead to false signals.

Lagging Indicator: Supertrend lags, so trades may start slightly after a trend begins.

Sensitive Settings Can Increase False Signals: Lower multipliers make Supertrend more sensitive, but they also increase the risk of false breakouts.

Supertrend Indicator vs Moving Average

The Supertrend and the Moving Average both indicate trend direction, but use different methods.

A Moving Average smooths price moves to show the overall direction, but doesn’t give direct buy or sell signals.

Supertrend shows trend direction and gives clear signals via colour changes, reacting to price speed.

In simple terms, moving averages help you see the trend, while the supertrend helps you decide when to enter or exit.

Best Indicators to Combine with Supertrend

The supertrend indicator works well on its own. But you can combine it with the following technical indicators to reduce false signals and improve accuracy.

Exponential Moving Average (EMA)

EMA defines the trend direction. If the price is above the EMA and the supertrend turns green, it signals a buy. If the price is below the EMA and the supertrend turns red, it confirms the downtrend.

Relative Strength Index (RSI)

RSI measures whether a stock is overbought or oversold. If the supertrend gives a buy signal and RSI is not in the overbought zone, the signal becomes stronger.

Moving Average Convergence Divergence (MACD)

MACD helps confirm trend momentum. If the supertrend turns green and MACD shows a bullish crossover, it adds more confidence to the trade.

Volume Indicator

Volume shows how strong a price move is. If the supertrend signals and trading volume increase, it usually indicates strong participation.

Is the Supertrend Indicator Reliable for Intraday Trading?

Yes, the supertrend indicator can work well for intraday trading strategies if used properly. It performs best when the market is clearly moving in one direction during the day. Since it follows price movements, it can provide quick buy and sell signals on shorter timeframes. However, if the market is moving sideways, it may give wrong signals. To make it more reliable, use it with EMA or volume, and always keep a stop-loss.

Common Mistakes While Using the Supertrend Indicator

Many beginners make the following mistakes, which can reduce the effectiveness of the Supertrend indicator.

Relying solely on the supertrend, without confirming with other indicators like EMA or RSI, can lead to poor decisions.
Don’t blindly follow every signal, as the supertrend doesn’t perform well in sideways markets.
Frequent adjustments to ATR or multiplier settings can create inconsistencies.
You should always use a stop-loss, as risk management is crucial, even with strong signals.
Entering too early can result in false signals. You should always wait for the candle to close.
