Stop-loss and take-profit orders are essential risk management tools. Without them, you’re gambling, not trading.
Types of Stop-Loss Orders
| Type | How It Works | Best For |
|---|---|---|
| Market stop-loss | Triggers a market sell at current price | Fast exits |
| Limit stop-loss | Triggers a limit order at specified price | Avoiding slippage |
| Trailing stop-loss | Moves up as price rises | Trend following |
| Time-based stop | Exits after set time period | Day trading |
Where to Place Stop-Loss
| Method | Description |
|---|---|
| Below support | Place just below a known support level |
| Below recent low | Place below the most recent swing low |
| Technical level | Below moving average, trendline, or Fib level |
| Fixed percentage | 2-5% below entry (simple but less precise) |
| ATR-based | Below entry minus 1.5-2× ATR |
The 1% Rule
Never risk more than 1% of your trading capital on a single trade.
| Account Size | Max Risk per Trade |
|---|---|
| £1,000 | £10 |
| £5,000 | £50 |
| £10,000 | £100 |
| £50,000 | £500 |
Position Sizing with Stop-Loss
Calculate your position size:
Position size = (Account × Risk %) / (Entry - Stop loss)
Example:
- Account: £10,000
- Risk: 1% = £100
- Entry: £50
- Stop loss: £48
- Position size = £100 / (£50 - £48) = 50 units = £2,500
Take-Profit Strategies
| Strategy | Description |
|---|---|
| Fixed risk/reward | 1:2 or 1:3 reward-to-risk ratio |
| Resistance level | Take profit at known resistance |
| Fibonacci extension | Take profit at 161.8% extension |
| Trailing take-profit | Let profit run until trend reverses |
| Partial takes | Take 50% at target, let 50% run |
Risk/Reward Ratio
| Ratio | Win Rate Needed | Verdict |
|---|---|---|
| 1:1 | 50% | Break even (before fees) |
| 1:2 | 33.3% | Profitable |
| 1:3 | 25% | Profitable |
| 1:5 | 16.7% | Profitable |
A 1:2 risk/reward with a 40% win rate is highly profitable.
Common Mistakes
| Mistake | Why It’s Bad |
|---|---|
| No stop-loss | One bad trade wipes out gains |
| Stop too tight | Gets stopped out by normal volatility |
| Moving stop wider | Defeats the purpose |
| Not adjusting in profit | Lets winners become losers |
| Too many partial takes | Caps upside |
Trailing Stop Example
- Buy at $100
- Set trailing stop at 5%
- Price rises to $120 — stop moves to $114
- Price rises to $130 — stop moves to $123.50
- Price drops to $123.50 — stop triggers
- Profit locked: $23.50/share (23.5% gain)
Bottom Line
A stop-loss is non-negotiable. Determine your stop placement before entering a trade, calculate position size based on risk, and set a take-profit at a level with a favorable risk/reward ratio. The best traders focus on risk management first, profits second.
Developing your stop-loss discipline
The hardest part of using stop-losses is not placing them — it is leaving them in place. The temptation to move a stop wider “just a little” to give the trade more room is overwhelming, especially when price is approaching your stop level. But every time you widen a stop, you are increasing your risk beyond what you originally planned, and you are turning a controlled loss into an uncontrolled one. Write your stop level down before you enter the trade and commit to it.
Equally important is the habit of moving your stop to breakeven or into profit once the trade has moved in your favour. If you enter at £50 with a stop at £48 and price moves to £54, moving your stop to £50 or £51 eliminates the risk of the trade turning into a loss. This psychological shift — from “hoping it works out” to “the worst case is I break even” — transforms your trading. Partial take-profits and trailing stops are extensions of this same principle: once a trade is working, your job shifts from managing risk to protecting gains.
Integrating stops and targets into a complete trading plan
A stop-loss and a take-profit are not afterthoughts — they are the core of your trade plan, and they should be determined before you enter the position. The sequence matters: first identify your entry signal, then place your stop at a logical technical level, then calculate your position size to keep risk at 1%, and only then set your take-profit target based on a favourable risk/reward ratio. If the target does not offer at least 1:2 reward-to-risk, the trade is not worth taking regardless of how compelling the setup looks.
Keep a log of every trade with entry, stop, target, position size, and actual result. After fifty trades, you will have enough data to see which stop-placement methods work best for your style and which take-profit strategies capture the most value. Some traders find that trailing stops outperform fixed targets; others do better with partial exits at predetermined levels. The data will tell you — trust it over gut feeling.
