Trailing Stop Loss Strategy: Point, Percentage and ATR Trails Explained

A trailing stop loss strategy deals with a question every trader hits eventually: once a trade starts working, what do you do with the stop? A fixed stop guards you on the way in, but it does nothing for the profit you build after that. A trailing stop climbs behind a long position as price rises and holds still when price falls, so a winner gradually becomes a trade that can’t turn into a big loss. We’ll go through the three usual ways to trail (fixed points, a percentage, and volatility-based ATR trails), how the new trailing stoploss for GTT orders on Zerodha’s Kite works, and the mistakes that leave a trail too tight or too loose.

Still working out where your first stop goes? Our guide to stop loss in trading covers that, and the risk management in trading pillar shows how stops tie in with position size and risk per trade.

What a trailing stop loss strategy actually does

An ordinary stop loss sits wherever you put it. Zerodha’s announcement of trailing stoploss on Kite web gives a neat example. You buy at ₹100 with a stop at ₹90, and the stock runs to ₹140. The stop is still at ₹90, so one sharp reversal could take back a big chunk of the move. The answer is to keep lifting the stop as price climbs, but doing that by hand means watching the screen and editing orders over and over.

A trailing stop does exactly that one job for you. On a long position, where the exit is a sell order, the stop trigger goes up as price goes up and stays at its last level when price drops. On a short position, where the exit is a buy order, it’s reversed: the trigger comes down as price falls and holds when price rises. Either way, the stop only ever moves in the direction that tightens your protection.

That one-way movement is really the whole point. You can still get stopped out, but after a decent run the exit sits nearer your entry, or above it. What’s left to decide is how far behind price the stop should trail, and that’s where the three methods split.

A trailing stop does not predict where a trend ends. It decides in advance how much of an open profit you are willing to give back before you admit the move is over.

Method 1: Fixed-point trailing stop

The simplest version keeps a fixed rupee gap between the highest price since entry and your stop. Kite uses this model. In Zerodha’s example the stock is at ₹100 and you place a sell GTT with a stop-loss trigger at ₹90 and a trailing point of ₹1. The gap starts at ₹10, and each time the stock moves ₹1 your way, the trigger moves up ₹1:

• The stock goes to ₹105, so the trigger moves to ₹95.
• The stock goes to ₹130, so the trigger moves to ₹120.
• The stock then drops to ₹125, and the trigger stays at ₹120.

The stop has gone from ₹90 to ₹120 while the trade ran your way. Zerodha makes two points here. The trigger moves in fixed steps, not tick by tick. And hitting ₹120 doesn’t guarantee you get out at ₹120: once the trigger fires, an order goes in, and the fill depends on market conditions, liquidity and price movement.

Fixed points are easy to grasp and easy to set. The problem is that a rupee gap means very different things on different stocks. ₹10 is a wide cushion on a ₹100 stock and barely anything on a ₹3,000 one, so you can’t copy one number across your whole watchlist.

Method 2: Percentage trailing stop

A percentage trail solves the scaling issue by keeping the stop a set percentage under the highest price reached. Take an illustrative case (made-up numbers, just to show the arithmetic, not a real trade). You buy at ₹500 with an 8% trail, so the first stop is ₹460. If the stock later peaks at ₹600, the stop goes up to ₹552, which is 8% below ₹600. If it then slips to ₹570, the stop stays at ₹552.

Positional traders and investors who hold for weeks like percentage trails. The catch is that they don’t care how volatile a stock is. An 8% trail could be loose on a sleepy large-cap and much too tight on a small-cap that moves 5% on a normal day. Kite’s trailing stoploss works in points, so if you’d rather use a percentage, you have to convert it to rupees yourself when you place the order. A number of commenters on Zerodha’s announcement asked for percentage and ATR-based trails, and the company said it had noted the feedback. Treat those as requests, not features.

Method 3: Volatility-based trail with ATR and the Chandelier Exit

The third approach sets the gap from the stock’s own volatility. The standard yardstick is the Average True Range (ATR), developed by Welles Wilder, which averages each bar’s true range using the prior close, current high and current low. Our guide to the average true range indicator walks through the calculation.

The best-known ATR trail is the Chandelier Exit. StockCharts ChartSchool says Charles Le Beau developed it and Alexander Elder featured it in his books. On a daily chart with default settings, it takes the highest high of the last 22 days and subtracts three times the 22-day ATR:

• Chandelier Exit for longs = 22-day high minus ATR(22) × 3
• Chandelier Exit for shorts = 22-day low plus ATR(22) × 3

ChartSchool explains that 22 is used because a month has roughly 22 trading days, and that the long exit “hangs” three ATRs under the period high, giving the trade a cushion of three times its usual volatility. An illustrative example: if a stock’s 22-day high is ₹600 and its 22-day ATR is ₹20, the long exit sits at ₹600 minus ₹60, which is ₹540. When volatility picks up and ATR widens, the exit drifts further away. When the stock grinds up quietly, the exit follows it.

ChartSchool also says volatile stocks may need a bigger multiplier to cut down whipsaws, and quieter ones a smaller multiplier to make the exit more responsive. In its own example the multiplier went up to 5 for a volatile technology stock that kept poking through the standard setting during a downtrend. The real advantage of an ATR trail is that the gap fits the stock, and that’s why plenty of swing traders pick it over a fixed number.

The right trailing distance is the one that sits outside a stock’s normal daily noise. Inside that noise, the stop gets hit by randomness rather than by a real change in trend.

How trailing stoploss works on Zerodha Kite GTT

Zerodha rolled out trailing stoploss for GTT (Good Till Triggered) orders on Kite web on June 23, 2026. Its support page on trailing stoploss now has the steps for both the Kite app and Kite web. Here are the rules that matter, from Zerodha’s pages:

• Where it works: NSE, BSE, NFO, BFO and MCX, on CNC, MTF and NRML product types.
• Which side: in equity, trailing is only on the sell side, to protect a long holding. In NFO it works on both buy and sell GTTs.
• Order types: you can add trailing to Single and OCO (One Cancels the Other) GTTs. For an OCO, Zerodha staff replied on the announcement that the target stays fixed and only the stoploss moves.
• What moves: each time the stop trails, Kite shifts both the stop-loss trigger and the limit price by the same trailing point.
• Editing resets it: edit the trigger price after placing the GTT and the trailing reference resets to the last traded price at the moment of the edit.
• Watermark price: on a sell GTT, Kite tracks the highest price since the GTT was created or last changed, and uses that to decide when the next adjustment kicks in.

There’s also a minimum trailing point, and it depends on price. For stocks and futures, Zerodha’s table puts it at ₹1 for prices from ₹500 to ₹1,000, ₹2 from ₹1,000 to ₹2,500, and ₹5 from ₹2,500 to ₹10,000. For options it’s ₹5 for premiums from ₹100 to ₹500. Which slab applies is decided by the lower of the last traded price and the trigger price.

The wider GTT rules matter just as much. A GTT stays live for up to 365 days, and triggers only fire during market hours: until 3:15 PM for F&O stocks, 3:30 PM for non-F&O stocks and 3:40 PM for F&O contracts. Each trigger is good for one use, so if it fires and the order doesn’t execute, you need a fresh GTT. GTTs get cancelled when a corporate action like a bonus, split, rights issue or amalgamation has an impact of more than 2% of market value. Sell GTTs on equity holdings need CDSL TPIN authorisation unless you’ve submitted a POA or DDPI. And since GTT is offered for CNC, NRML and MTF, intraday MIS positions aren’t covered. For regular stop orders on intraday trades, see our walkthrough on how to set stop loss in Zerodha.

Gaps: the risk no trailing stop removes

A trailing stop is a trigger, not a guarantee. Zerodha’s GTT page says a GTT fires even if a stock opens with a gap past the trigger price, and the order goes in at your limit price. If price has already blown through that limit, a limit order may not fill at all, and Zerodha says an unexecuted order is cancelled at the end of the day like any normal order. A market order with market protection gives you a better chance of a fill, but after a nasty overnight gap, say on weak quarterly results, the price you get can still be well under your trigger.

So the trail has to go with sensible position size. If a gap through your stop overnight would really hurt, the position is too big for the stock’s risk, no matter what the trailing setting says.

How far behind price should the stop sit?

No single gap is right for everyone, but a few practical rules go a long way:

• Match the trail to your timeframe. Someone swing trading over several days or weeks needs a wider trail than an intraday trader. A gap set off a 5-minute chart will usually be far too tight for a positional trade.
• Start with volatility. Look at the stock’s ATR first. A trail narrower than its typical daily range will probably get tripped by ordinary movement. For trend trades, the Chandelier default of three ATRs on a daily chart is a common place to start.
• Use structure where it fits. A lot of traders move the stop up to just below the latest higher swing low on the daily chart rather than trailing every rupee. It’s a manual trail, but it follows how the trend is actually building. Our swing trading strategies for beginners guide shows where those swing lows come from.
• Don’t start trailing too soon. If the trail kicks in the moment you enter, it effectively tightens your initial stop. One way around this is to leave the initial stop fixed until the trade has moved your way by at least the distance to that stop, and only then start trailing.
• Write the rule down before you enter. Changing the trailing distance mid-trade out of fear or greed defeats the purpose. On Kite, editing the trigger resets the trailing reference too.

Sizing the position around the stop

The trailing stop decides how much profit you hand back. Your initial stop and position size decide how much you can lose. Illustrative example: with a ₹5,00,000 account and a 1% risk rule, you can lose ₹5,000 on the trade. If the initial stop is ₹40 below entry, that works out to 125 shares (₹5,000 divided by ₹40). A wider ATR-based stop means fewer shares and a tighter stop means more, but the rupee risk doesn’t change. Our guide on the risk reward ratio in trading helps you judge whether the possible move is worth that risk.

Trailing stop mistakes that cost traders money

• Trailing too tight. By far the most common one. The stock has a normal pullback, the stop gets hit, and the trend keeps going without you.
• One rupee gap for every stock. A fixed-point trail has to be reworked for each price level and each stock’s volatility.
• Forgetting the order type. Put the limit price too close to the trigger and it may never fill in a fast fall.
• Assuming it covers everything. On Kite, GTT trailing doesn’t cover MIS intraday positions, and corporate actions can cancel GTTs, so check your protection is still live.
• Moving the stop down. A trailing stop only goes one way. Dropping a long stop to “give the trade room” turns a plan into hope.

The bottom line

A trailing stop loss strategy isn’t about nailing the top of a move. It banks part of a winning trade without you having to stare at the screen all day. Fixed-point trails are simple, and they’re what Kite’s GTT trailing offers today. Percentage trails scale with price, while ATR-based trails like the Chandelier Exit scale with volatility. Whichever one you use, set the distance outside the stock’s normal noise, size the position so a gap through the stop won’t sink you, and fix the rule before you enter.
