Stop loss vs take profit — when to use which?

A stop loss is the foundation, because a single position left without one can wipe out an entire account. Picture a trader who opens a long position on EUR/USD at 1.0850, is sure it will rise, and sets no loss boundary. The market falls, she waits for it to "come back", adds more contracts, and two days later the rate is 200 pips lower and the broker closes what is left through a margin call. Half the account gone on one decision. A stop loss (a protective exit order) and a take profit (a profit-taking order) exist precisely so this does not happen — below I explain where to place them, in what ratio, and why missing the first empties more accounts than any other mistake.

What exactly is a stop loss

A stop loss (a protective order that automatically closes a position at a loss) is a price level parked on the broker's server. When the rate touches it, the position closes by itself, without you sitting at the screen. For a long position you place it below the entry price; for a short position, above. That is the difference between a controlled loss and a loss whose size you don't know until you sit down at the monitor.

Take a concrete case. Anna opens a long position on EUR/USD at 1.0850 and sets a stop loss at 1.0820. That is a 30-pip distance. If she trades a single mini lot (0.1 lot), each pip is worth about 1 USD, so the maximum loss is roughly 30 USD — whether she is asleep, at work, or having lunch. Without that order, the same position during a sudden 150-pip drop would mean a loss five times larger, and during a 400-pip drop, a disaster, especially at high leverage.

This is the heart of it: a stop loss is not there to make you right. It is there to make a mistake cost a small, known amount decided in advance. A trader who knows the maximum loss before opening a position makes decisions with a cool head. A trader without a stop loss improvises under pressure — and pressure is the worst adviser on the market.

What exactly is a take profit

A take profit (a profit-taking order that automatically closes a position at a gain) works as a mirror image. It is the level at which the broker closes the position with a profit once the market reaches your target. For a long position you set it above entry; for a short position, below. Anna from the earlier example, opening at 1.0850, can set a take profit at 1.0910 — that is 60 pips of profit. It is worth knowing that a stop-loss fills at the bid price and a take-profit at the ask (reversed for a short position) — this mechanism, crucial for accurate planning, is explained in the article on which price fills your stop-loss and take-profit.

Why hand the decision to a machine when you can close manually? For two reasons. The first is discipline. Without a defined target it is easy to stay in a position because "I'll earn just a bit more" — and the market very often retraces, so what was a 60-pip gain turns into 10 pips or zero. The second reason is practical: a take profit fires at night, during a meeting, while you sleep. You don't have to stare at the chart for eight hours so as not to miss the moment.

It is worth remembering one asymmetry, though. A stop loss is mandatory — it protects against a loss whose scale you don't control. A take profit is very useful but not as critical: at worst, its absence means giving back part of a profit rather than losing capital. So if you have to pick just one order to hold to with iron discipline, let it always be the stop loss.

Where to place a stop loss — beyond the level, not on a round number

The most common beginner mistake is setting a stop loss "by feel" — a flat 20 pips, a tidy 1.0800, a nice-looking number. The market does not know your round numbers. A stop loss should follow the structure of the chart, not its aesthetics. The best method for most traders is to place it just beyond the nearest support level (for a long position) or resistance level (for a short position).

The logic is simple. A support level is a place where the rate has already stalled and turned several times — that is where other market participants' buy orders sit. If price breaks through that level, your thesis about a rise stops being valid. A stop loss placed five to ten pips below support says: "as long as the market respects this level I stay; once it breaks it, I leave, because I was wrong about direction." That is a stop loss with a reason, not one drawn with a ruler.

A second important rule: do not place it exactly on a round number such as 1.0800 or 1.1000. A great many orders cluster around such levels, and brief "stop hunts" often happen there — price touches the round number, sweeps the protective orders, and turns back. It is better to set the stop loss a few pips farther, beyond the actual technical level, than precisely on a magnet that attracts violent moves. I cover the support-and-resistance mechanism that drives these levels in more depth in the section on technical analysis.

Risk-reward ratio — why it decides survival

A take profit is not chosen in isolation from the stop loss. It is chosen in proportion to it — what is called the risk-reward ratio. If you risk 30 pips on the stop loss and aim for 60 pips on the take profit, you have a reward-to-risk of 2:1. If you aim for 90 pips at the same risk, you have 3:1. This is one of the most important numbers in all of trading, more important than the win rate itself.

Why more important? Because it lets you make money even when most trades are losers. Let's count on a 1,000 USD account where you risk 1 percent, that is 10 USD, per trade. Over a hundred trades at a reward-to-risk of 2:1, you only need 40 of them to be winners — and you still come out ahead.

Look at the first row. At a 1:1 ratio with half the trades winning you are exactly at zero — and once you add the spread and commission, even below the line. That is why experienced traders usually do not open a position whose potential profit is not at least twice the risk. What counts is not how often you are right, but how much you earn when you are, compared with how much you lose when you are wrong. I develop the same idea in the section on risk management.

„The Holy Grail of trading is position sizing and risk control — not a brilliant entry system. How much you risk per trade decides your survival far more than where you enter the market." — Van K. Tharp, *Trade Your Way to Financial Freedom*, McGraw-Hill, 1998.

Trailing stop — when the profit should grow and the loss should not

A trailing stop is a variant of the ordinary stop loss that follows price as the market moves in your favour — but never moves back the other way. You set it, say, 30 pips behind the current rate. When price rises 50 pips, the trailing stop climbs with it and stays 30 pips below the new, higher level. When the market turns, the order closes the position with part of the profit you built up.

What is it good for? It solves the eternal dilemma: close now at a sure profit, or let the position breathe in the hope of more. A trailing stop lets the profit grow while the trend lasts and automatically protects the result when the trend breaks. It works best in trend-following strategies, in a calm one-directional move. It works worse in a ranging market, where the rate swings both ways and the trailing level gets hit prematurely. I break the mechanism down step by step in a separate article on how a trailing stop works.

A related and safe technique is moving an ordinary stop loss to the entry level once the market has moved in your favour by a set number of pips. This is the so-called break-even stop loss — I walk through it step by step in the piece on what break-even is and how to move your stop-loss to BE. From that point on, at worst you close the position at zero rather than at a loss. It is the only acceptable direction for moving a stop loss — closer to price, never farther. It is also worth knowing that stop-loss and take-profit orders work even when the computer is off — that common question gets a dedicated answer in the article on whether SL and TP work with MT4 closed.

Three mistakes that cost the most

Over years of watching the market these three errors have been the most frequent — and each can undo an otherwise sound strategy.

1. A stop loss placed too close to price. A protective boundary at five to ten pips looks cautious, but in practice every random noise spike hits it. You exit at a loss only to watch the rate return to your entry point and continue in the direction you predicted. That is not caution, it is giving money away for market noise. A stop loss needs a distance matched to the pair's volatility — on EUR/USD that is usually 30–60 pips for an intraday position.
2. A take profit beyond the reach of the time horizon. If you close positions the same day, a 200-pip target on EUR/USD will most often not be reached — major pairs rarely cover that distance in a single day. Match the take profit to the pair's typical volatility within your horizon, ideally using the ATR indicator (Average True Range).
3. Moving the stop loss farther mid-trade. This is the most dangerous of the three. Price nears the protective boundary, the trader panics and pushes the stop loss away "to give the market more room". The result: a planned 30-pip loss turns into 80, and sometimes into a margin call. A stop loss may only be moved closer to price, toward securing profit — never toward enlarging the loss.

The common denominator of all three mistakes is deciding on the exit after opening the position, under the influence of emotion. A good exit plan is made earlier, with a cool head — before real money and real stress are in play.

What to do tomorrow — a stop-loss and take-profit checklist

You can run through the steps below today, on a demo account or on your next live position. Each takes a few minutes and requires buying no tool at all.

1. Mark the stop loss beyond a technical level before you open the position. Open the EUR/USD chart on the hourly timeframe, find the nearest local low (for a long position) and set the stop loss five to ten pips below it. If that comes out below 15 pips, the level is too close; if above 100 pips, it is too far for intraday trading.
2. Size the position from the risk, not the other way round. Decide that you risk no more than 1 percent of the account per trade, then choose the number of lots so that the stop-loss distance in pips fits within that amount. I explain the conversion step by step in the article on pip value per pair.
3. Set the take profit at a ratio of at least 2:1 to the stop loss. If you risk 30 pips, place the target at a minimum of 60 pips — and check on the chart whether there is a strong resistance level on the way that would stall the rate before the target. If there is, shorten the target to that level or look for another position.
4. After a move in your favour, shift the stop loss to break-even. Once the profit reaches roughly the distance of your original risk, move the stop loss to the entry level. From that moment the trade closes at zero in the worst case — you free your mind and stop staring at the chart.
5. Record every trade in a journal with the stop-loss distance and the risk-reward ratio. After a month, count how many positions you opened at a ratio worse than 2:1 — those are the trades you probably should not have taken. If their share exceeds 30 percent, you have concrete work to do on entry selection.
