TrendTrend-following overlay with trailing stop

Supertrend

An ATR-based trend line that flips sides and trails as a stop-loss.

Quick answer: Supertrend is a trend-following overlay by Olivier Seban that plots a single line, based on price and the Average True Range, which sits below price in an uptrend and above it in a downtrend, flipping sides to signal trend changes and acting as a trailing stop.

In simple words

Supertrend draws one clear line on your chart that does two jobs at once. It tells you the trend direction — the line sits below price and is green in an uptrend, above price and red in a downtrend — and it acts as a trailing stop, because when price closes through the line, the trend has flipped and the line jumps to the other side. Its distance from price is set by the ATR, so it automatically gives more room in volatile markets and less in calm ones. Its simplicity and clear buy/sell flips make it hugely popular with Indian intraday traders.

Supertrend — visual

How Supertrend looks on a chart

Supertrend flips from below price (uptrend) to above price (downtrend) when price closes through it. Its ATR-based distance widens in volatility and tightens in calm.

Professional explanation

How the line is built

Supertrend starts from the median price (high+low)/2 and adds or subtracts a multiple of the ATR to form an upper and a lower band. In an uptrend it plots the lower band as a rising support line; in a downtrend it plots the upper band as a falling resistance line. The line only ever ratchets in the trend's favour — it never loosens — so it behaves as a trailing stop that locks in as price advances.

The flip and the ATR distance

The signal is the flip: when price closes below the rising lower band, Supertrend flips above price and turns bearish; when price closes above the falling upper band, it flips below and turns bullish. Because the band distance is ATR × a multiplier, the stop sits farther from price when volatility is high and closer when it is low — an adaptive buffer that a fixed-point stop cannot match.

Two settings that change everything

Supertrend has just two inputs: the ATR period (commonly 10) and the multiplier (commonly 3). A smaller multiplier keeps the line close to price, giving early, frequent flips and more whipsaw; a larger multiplier keeps it far away, giving fewer, later, more reliable flips. Tuning the multiplier to the instrument's volatility and your timeframe is the whole art of using Supertrend.

Strength in trends, weakness in ranges

In a sustained trend Supertrend is superb — it keeps you in the move and trails a sensible stop with almost no effort. Its weakness is the range: when price oscillates sideways, Supertrend flips back and forth, generating a string of losing whipsaw signals. That is why experienced traders pair it with a trend-strength filter and avoid trading its flips in choppy conditions.

Formula

Supertrend formula

Upper/Lower Band = (High+Low)/2 ± Multiplier × ATR; Supertrend follows the band in the trend's direction

The line uses the ATR (default period 10) times a multiplier (default 3). In an uptrend it tracks the lower band; in a downtrend the upper band. A close through the line flips the trend.

(High+Low)/2 — The median price, the basis of the bands
ATR — Average True Range — the volatility measure setting the band distance
Multiplier — Factor applied to ATR (default 3) that sets how far the line sits from price
Band — Upper or lower line; Supertrend plots whichever matches the current trend

How it is calculated

Compute the ATR over the chosen period (default 10).
Form the basic upper band = (High+Low)/2 + Multiplier × ATR and lower band = (High+Low)/2 − Multiplier × ATR.
Ratchet the bands so they only tighten in the trend's favour, never loosen.
In an uptrend plot the lower band; in a downtrend plot the upper band.
When price closes through the plotted line, flip the trend and switch to the opposite band.

Interpretation & signals

Traders read Supertrend's colour and side for trend direction, its flips as buy/sell signals, and the line itself as a trailing stop-loss that adapts to volatility.

Buy / bullish signals

Supertrend flips from above price to below it (turns green) — a buy signal.
Price closes above the falling upper band, triggering the bullish flip.
In an uptrend, price pulls back toward the green line and holds.
The flip aligns with a higher-timeframe uptrend (filtered entry).

Sell / bearish signals

Supertrend flips from below price to above it (turns red) — a sell signal.
Price closes below the rising lower band, triggering the bearish flip.
In a downtrend, price rallies toward the red line and fails.
The flip aligns with a higher-timeframe downtrend (filtered entry).

False signals to beware

In a sideways range, Supertrend flips repeatedly, producing whipsaw losses.
A small multiplier flips too easily on noise.
A flip against the higher-timeframe trend often fails.

Settings, timeframe & conditions

Best settings

ATR period 10, multiplier 3 (common default)

Avoid

Small multiplier in a choppy market (constant whipsaw)

Works best in

Sustained, trending markets

Struggles in

Sideways ranges (repeated flips)

Advantages & limitations

Advantages

One line gives both trend direction and a trailing stop.
ATR-based distance adapts the stop to volatility.
Clear, unambiguous buy/sell flips.
Simple to use and extremely popular for intraday.

Limitations & disadvantages

Whipsaws badly in ranging markets.
Lagging — the flip comes after the turn.
Only two settings, so limited flexibility.
No sense of momentum or overbought/oversold.

Combining Supertrend with other indicators

Average Directional Index — ADX filters Supertrend: take flips only when ADX shows a strong enough trend, avoiding range whipsaws.
Exponential Moving Average — A higher-timeframe EMA sets the trend so you take only the Supertrend flips that align with it.
Average True Range — Supertrend is built on ATR; understanding ATR clarifies why the line's distance changes with volatility.

Practical examples (Nifty & Bank Nifty)

NIFTY example

On the 15-minute Nifty chart, Supertrend(10,3) flips green as price closes above the upper band near 24,300 and then trails below the rally as a rising stop up to 24,650, keeping the trader in the whole intraday move. The exit comes cleanly when price closes back below the line and it flips red — a single tool handling both entry and trailing exit.

BANKNIFTY example

Bank Nifty's larger swings mean the same (10,3) Supertrend sits farther from price because its ATR is bigger — the adaptive distance in action. In a trending session it trails a wide, sensible stop; but on a choppy, range-bound day the line flips red and green repeatedly, so an experienced trader adds an ADX filter and sits out the whipsaws when Bank Nifty is not trending.

Common mistakes

Trading every flip in a sideways market.
Using too small a multiplier and getting whipsawed on noise.
Ignoring the higher-timeframe trend when taking flips.
Treating Supertrend as a momentum tool — it only reads trend and stop.

Professional usage

Professionals and active Indian intraday traders use Supertrend mainly as a trailing-stop and trend-direction engine rather than a blind flip system. They take flips only in the direction of a higher-timeframe trend or a strong ADX reading, and they lean on the line as an adaptive, volatility-scaled stop that trails winners without constant adjustment. In ranges they simply stand aside, because they know the flips there are the tool's Achilles heel.

Key takeaway

Supertrend is a single ATR-based line that shows trend direction by which side of price it sits on and doubles as a volatility-scaled trailing stop, flipping to signal trend changes. It excels in trends and whipsaws in ranges, so filter its flips and avoid choppy markets.

Frequently asked questions

What is the Supertrend indicator?

Supertrend is a trend-following overlay, created by Olivier Seban, that plots a single ATR-based line sitting below price in an uptrend and above it in a downtrend. It signals trend changes when price closes through the line and doubles as a trailing stop.

What are the best Supertrend settings?

The common default is an ATR period of 10 with a multiplier of 3. A smaller multiplier gives earlier but noisier flips; a larger one gives fewer, more reliable flips.

How does Supertrend work?

It builds bands a multiple of the ATR away from the median price, plots the lower band in uptrends and the upper band in downtrends, and flips sides when price closes through the line. The line only ratchets in the trend's favour, acting as a trailing stop.

Is Supertrend good for intraday trading?

Yes, it is one of the most popular intraday tools in India, especially on 5- and 15-minute charts, because it gives clear flips and an adaptive trailing stop. It works best in trending sessions and whipsaws in ranges.

Why does Supertrend give false signals?

In sideways, range-bound markets price oscillates across the line, so Supertrend flips back and forth, producing whipsaw losses. This is its main weakness, mitigated by a trend-strength filter.

What is the multiplier in Supertrend?

The multiplier scales the ATR to set how far the line sits from price. A larger multiplier keeps the line farther away for fewer, later flips; a smaller one keeps it close for earlier, noisier flips.

Is Supertrend a leading or lagging indicator?

Supertrend is a lagging indicator — the flip comes after the trend has already begun to turn. Its value is in clearly defining direction and trailing a stop, not predicting turns.

Can Supertrend be used as a stop-loss?

Yes, the line itself is a natural trailing stop because it ratchets in the trend's favour and its ATR basis adapts the distance to volatility. Many traders exit when price closes through it.

How is Supertrend different from a moving average?

A moving average smooths price, while Supertrend is an ATR-band overlay that flips sides and trails as a stop. Supertrend gives a discrete direction and stop rather than a smoothed price line.

Does Supertrend work on Bank Nifty?

Yes, and because it is ATR-based, it automatically sits farther from Bank Nifty's more volatile price, giving a wider adaptive stop. It still whipsaws in ranges, so a filter helps.

Who created the Supertrend indicator?

Supertrend was developed by French trader Olivier Seban. It has become especially popular among Indian retail and intraday traders.

Voice search & related questions

What is Supertrend in simple words?

Supertrend is a line on your chart that sits below price and turns green in an uptrend, and sits above price and turns red in a downtrend, flipping over to signal when the trend changes.

What are the best Supertrend settings?

The most common setting is an ATR period of 10 and a multiplier of 3, which balances early signals against whipsaw.

Is Supertrend good for day trading?
