Trailing stop strategies to lock in profits on NSE/BSE equity positions. Covers ATR trail, structure trail, MA trail, chandelier exit, and the recommended hybrid approach.

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 3 are distinctive, and 0 are very specific to this project.

  1. Distinctive:

    No dependencies required. Provide entry, current price, and ATR manually.

  2. Distinctive:

    Use closing price vs MA — if daily close is below the MA, exit next day.

    line 66
  3. Distinctive:

    Don't overtighten: If you're trailing too tight, you'll get stopped out on normal pullbacks.

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Trailing Stops

Once a trade is profitable, trailing stops protect your gains while letting winners run.

Prerequisites

No dependencies required. Provide entry, current price, and ATR manually. Enhanced with Groww MCP (live ATR, candles, MAs) or yfinance.

Data Needed

  1. Entry price and current price: Known or from get_quotes_and_depth
  2. ATR(14): get_historical_technical_indicators from Groww, or user-provided
  3. Recent swing lows/highs: fetch_historical_candle_data (daily)
  4. Moving averages: SMA20, EMA50 from indicators
  5. Initial risk (1R): Entry - original stop-loss

The Hybrid Approach (Recommended)

This progressive system adapts as the trade matures:

Trade StageProfit LevelTrailing Method
Just entered0 to 1RFixed stop — don't trail yet, use initial stop-loss
Early profit1R gainedMove to breakeven — stop at entry price (eliminates risk)
Building profit2R gainedATR trail — highest close minus ATR(14) × 1.5
Strong runner3R+ gainedStructure trail — below most recent swing low

This works because:

  • Below 1R: Moving stop too early gets you shaken out on noise
  • At 1R: Breakeven means you can't lose money — psychological freedom to hold
  • At 2R: ATR trail gives the stock room to breathe while protecting most profit
  • At 3R+: Structure trail is tighter, appropriate when you have a large cushion

Individual Methods

ATR Trail

Trailing stop = Highest close since entry - ATR(14) × multiplier
Multiplier: 1.5 (tight), 2.0 (standard), 3.0 (loose)

Recalculate daily at market close. Only move stop up, never down.

Structure Trail

Trailing stop = Below the most recent higher low

Identify swing lows on the daily chart. Each new higher low becomes the new stop reference. Best for stocks making clear stair-step patterns.

Moving Average Trail

Aggressive: Trail below SMA20 (for fast trends)
Moderate: Trail below EMA50 (for steady trends)
Conservative: Trail below SMA200 (for long-term holds)

Use closing price vs MA — if daily close is below the MA, exit next day.

Chandelier Exit

Trailing stop = Highest high since entry - ATR(14) × 3.0

More aggressive than standard ATR trail. Good for volatile runners where you want to ride big swings.

Trailing Stop Rules

  1. Only move up, never down — a trailing stop is a ratchet
  2. Check daily at market close — don't adjust intraday (noise)
  3. Use closing prices for triggers — ignore intraday wicks
  4. When stop is hit: exit at next day's open, no exceptions
  5. Don't overtighten: If you're trailing too tight, you'll get stopped out on normal pullbacks. Give the stock room proportional to its ATR.
