Stop loss is an order placed with your broker to automatically sell a security when it reaches a specified price level, limiting your potential loss on a trade. It’s the most fundamental risk management tool in trading and essential for preserving capital.
How Stop Loss Works
When you enter a trade, you simultaneously place a stop loss order at a price that represents your maximum acceptable loss:
Stop Loss Price (Long) = Entry Price - Risk Amount
Stop Loss Price (Short) = Entry Price + Risk Amount
Example Calculation
Let’s say you buy Reliance shares:
- Entry Price: ₹2,500
- Risk per share: ₹50 (2% of entry)
Stop Loss = ₹2,500 - ₹50 = ₹2,450
If Reliance drops to ₹2,450, your position automatically closes, limiting your loss to ₹50 per share.
Types of Stop Loss Orders
| Type | How It Works | Best For |
|---|---|---|
| Fixed Stop | Set at a specific price that doesn’t change | Swing trading, position trading |
| Trailing Stop | Moves with price to lock in profits | Trend-following strategies |
| Percentage Stop | Set at a fixed % below entry | Quick position sizing |
| Volatility Stop | Based on ATR or standard deviation | Adapting to market conditions |
| Time Stop | Exit if trade doesn’t work within timeframe | Day trading, momentum plays |
What is a Good Stop Loss Distance?
| Trading Style | Typical Stop Distance | Risk Per Trade |
|---|---|---|
| Scalping | 0.1-0.3% | 0.25-0.5% of capital |
| Day Trading | 0.5-1% | 0.5-1% of capital |
| Swing Trading | 2-5% | 1-2% of capital |
| Position Trading | 5-10% | 1-2% of capital |
The key is matching your stop loss distance to your risk-reward ratio. A wider stop requires a larger potential reward to maintain a favorable ratio.
Why Stop Losses Can Be Problematic
While stop losses are essential, traders should be aware of their limitations:
-
Stop hunting - Market makers and large players sometimes push prices to trigger clusters of stop losses before reversing direction. Placing stops at less obvious levels can help avoid this.
-
Slippage - In fast-moving or illiquid markets, your stop may execute at a worse price than intended. This is especially common during news events or market opens.
-
Premature exits - Stops placed too tight can get triggered by normal market noise, stopping you out of trades that would have been profitable.
-
Gap risk - If the market gaps past your stop (common with overnight positions), you may experience a larger loss than planned. Stop limits can prevent execution entirely in such scenarios.
Stop losses should be placed at technically significant levels where your trade thesis is invalidated—not at arbitrary percentages or round numbers.
How to Set Stop Loss Correctly
Step 1: Identify Technical Level
Place your stop beyond a level of support (for longs) or resistance (for shorts):
- Below recent swing low for long positions
- Above recent swing high for short positions
- Beyond key moving averages (20, 50, 200 EMA)
- Outside consolidation ranges
Step 2: Calculate Position Size
Once you know your stop distance, calculate how many shares/lots to trade:
Position Size = (Account Risk Amount) / (Entry Price - Stop Loss Price)
Example: ₹10,000 risk budget, buying at ₹500 with stop at ₹480: Position Size = ₹10,000 / (₹500 - ₹480) = 500 shares
Step 3: Use Brokers with GTT Orders
Indian brokers like Zerodha, Upstox, and Groww offer GTT (Good Till Triggered) orders that remain active until your stop is hit—even across multiple trading sessions.
How JournalPlus Tracks Stop Loss
JournalPlus automatically analyzes your stop loss execution across:
- Planned vs actual exits - Did you stick to your stops?
- Stop loss hit rate - What percentage of trades hit your stop?
- Slippage analysis - How much did actual exits differ from planned stops?
- Risk-reward achieved - Compare intended R:R with actual R:R
This helps you identify whether your stops are placed correctly and if you’re maintaining discipline in executing your risk management plan.
