So now you know what stop losses are and how they're executed where do you place them, ie at what price levels? Sadly, there's no one size fits all answers but here are some ideas.
Money Stop Losses
The simplest stop losses are money stops where a fixed amount of cash is at risk. For example -
- You go long £5 of the FTSE at 4230
- You decide to risk £100 on the trade
- So enter a stop loss order to sell £5 FTSE at 4210 (4230 - 20 = 4210)
Percentage Stop Losses
Percentage stop losses can either be a percent of where the market is currently trading or a percent of your trading capital . For example, if using a percent of where the market currently is -
- If you go long the FTSE at 4200 and enter a 1% stop loss - that would be at 4158 (4200 x 0.99)
- If you went short the FTSE at 4200 a 3% stop loss would be at 4326 (4200 x 1.03)
However, as spread bets use leverage even a 1% or 2% move against your current position can result in significant losses. This is an important point.
So when using leverage many traders will prefer to use a percentage of their trading capital, usually in the 1% - 5% range. Assume you're risking 3% for this example -
- Your account has a balance of £5,000, 3% of that is £150
- You buy £2 of the FTSE at 4200 and so the stop loss order is placed at 4125 (75 x £2 = £150)
Technical Stops
Personally I like technical stop losses the best. This is where the stop level is placed above or below a certain chart point. Now, you may or may not like charts, but they are useful for gauging market behaviour.
Daily Vodafone Chart

The daily chart above is of Vodafone. The low of the recent move was 112p. The theory is that as 112p found support before probability states the level should find support again.
But the stop loss level shouldn't be at 112p, rather somewhere below this level to give the market some room to move. If it was me placing the stop loss I'd probably put it at 108p-109p.
Basically technical stops have some price relevancy built in, ie they're based on what the market has been doing. This in contrast to pure monetary stops which are placed at arbitrary price levels.
The recent high/low stop loss
As the name suggests these stop losses are placed above or below the recent high or low, perhaps for example yesterday's low or even today's low if you're day trading.
The reasoning behind these stops is similar to Technical Stops above. If a market has found support, ie excess buying at a certain point, then probabilities state it will do so again.
Again, how many points above or below the recent high/low should the stop be placed at?
This depends on many factors such as what the market is, how volatile it's been and possibly any forthcoming news. If it was the FTSE and in normal market conditions then a practical level would be 5-10 points above or below the high/low.
The dangers however of both technical stops and using the recent high/low is that these levels are also where many traders place their stops. This is why sometimes you'll see a market go crazy around one of these price points as many stop losses orders get hit at the same time. In such a case your stop loss might be filled with more slippage than normal.
Longer-term traders can also use recent highs and lows for guidance in stop placement. But instead of using the previous daily low, why not use the low of the previous week or month? This is normally a far better place to put your stop than a fixed percentage or monetary amount because again you're letting the market guide you.
Trailing Stop Losses
A trailing buy stop loss is where the stop level moves higher as the underlying market moves higher. Conversely a trailing sell stop will move lower as the underlying moves lower. For example -
- If you go long the FTSE at 4200 with a 25 point trailing stop loss, the stop level is 4175
- If/when the FTSE moves to 4201, the trailing stop also moves up by a point to 4176
- If/when the FTSE moves to 4210 the trailing stop level moves to 4185 and so on
Trailing stop losses are normally used to protect a profitable position and are hardly ever used to take out a new position.
Breakeven Stop Losses
A breakeven stop is a stop loss order that is placed at the same level as where the original trade was transacted. For example -
- You buy the FTSE at 4230 and it shoots up to 4250
- So far it looks like a good trade and you fully expect the market to continue to rise
- But you don't want a good winning trade to end up losing so you place a stop loss to sell the position at 4230, your original entry price
But you want to try to get some balance on how far the market should move in your favour versus placing a breakeven stop loss. For example, if you buy at 4230 and the market moves to 4235 a breakeven stop of 4230 would have a high chance of being executed. Traders therefore use them when the market has made a reasonable move in their favour, in the FTSE probably at least 20 points if not more.
Tight stop losses versus wide stop losses
This is an argument that has been going on for as long as stop losses have been around, and unfortunately it will never end as there's no right or wrong answer.
The question is this - is it better to use a tight stop loss (one that's near to where the position was opened) or a wide stop loss (one that is far away). An example, assume you bought the FTSE at 4200
- Tight stop loss level - 4190 (10 points)
- Wide stop loss level - 4150 (50 points)
Both have good and bad points.
The tight stop loss, at 4190, will lose you the least money but at the same time has a high chance of being hit as it's only 10 points away. The markets obviously never move in a straight line so it's possible you buy the FTSE at 4200, the market drifts lower to 4188 activating your stop loss, before rallying sharply to close at 4275.
The wide stop, at 4150 has far less of a chance of being hit. But if it is, the loss of 50 points will be relatively large. However, if the market sells off (after you've gone long at 4200) to 4185 before rallying sharply to close at 4275 clearly the wide stop was better, with hindsight of course.
Timing has to be considered
So which stop is better, tight or wide? It's hard to answer but on the whole I would think that wider stop losses are better because most traders struggle with their timing. We might for example forecast the FTSE 100 points higher over the next 2 days but in fact it takes 5 days. So with a wider stop loss we give the market more room and time to move.
Clearly though there has to be some balance struck towards how you trade the market.
If you're shooting for small and quick profits then tighter stops are normally better. But if trading weekly or even monthly moves wider stops are generally better. Yes, you'll lose more when wrong but then longer term positions should provide more profit as well.
Summary - When many people start trading spread bets the temptation is to use stop loss levels that are too near to where the current market is trading because they believe the risk is smaller. But they often forget the percentage chance of the stop loss level being hit is high.
One way to confront this problem is to initially use a wide stop when you first enter the market and then move the level as the trade evolves. For example -
- You go long the FTSE at 4200 with a view to holding the position for a few days thinking there's at least 100 points of profit available
- Place your initial stop loss at 4150
- Then, later in the day as you get a better feel for how the market is trading move the stop level higher
- And with online trading this is as simple as a few mouse clicks
Experience is Important when Placing Stops
This guide has shown there is no exact science when figuring out the level to place a stop loss. Sometimes many factors come into play and experience is often the key when deciding the right level to place them. Perversely you will find that you learn a fair amount by putting your stops in the wrong place.
While this is not good news in the short term it's often good news over the long run. Learning from your mistakes, assuming you do learn from them, is the best education a trader can receive.
The main error people make when first using stops is to place them too near to where the market is trading. If you want to cut down on the number of errors that you make when you start out, then try to place your stops far away from the current market price, giving the market plenty of room to naturally move around without stopping you out.
