Stop-Loss and Take-Profit Strategy
Decide where you'll exit (win or lose) before you enter, so emotion never picks for you.
A 3.0 : 1 plan only needs to win 25% of the time to break even. Set both exits before you enter. Never move the stop to give a loser "room".
Play with the planner above first. Set an entry, a stop, and a target, and watch your risk and reward update. Notice one thing: you're picking both exits before you have any money on the line. That's the whole module in one gesture.
The decision you must make before you click Buy
Here's the trap. You open a position, price moves against you, and now you decide where to get out. Except you can't decide clearly anymore, because fear is holding the pen. You'll widen the stop "just a little," tell yourself it'll come back, and turn a small planned loss into a big unplanned one.
The fix is boring and it works: decide both exits before you enter. When the trade is still hypothetical, you're calm and honest. That's the only version of you who should be allowed to set these levels.
Stop-loss: the price that caps the damage
A stop-loss is a pre-set exit price on the losing side. If price hits it, you're out. The damage stops there. You set it before you enter, not after you're hurting.
Your stop is not a suggestion. It's the single line that answers "how much can this trade cost me?" Everything downstream depends on it.
Take-profit: the price that locks the win
A take-profit is a pre-set exit price on the winning side. Price reaches it, you get paid, done. Beginners skip this because "what if it keeps going?" And then they watch a green trade round-trip back to zero because greed had no exit plan. Set the target up front so the win is real, not a screenshot you almost had.
Your stop is your risk: the same number from Module 2
This is the connection people miss. Back in position sizing, you decided how many dollars you'd risk on a trade, say 1% of your account. That number wasn't abstract. The distance from your entry to your stop is exactly what turns that dollar risk into a position size.
Wider stop → smaller position. Tighter stop → bigger position. Same dollars at risk either way. So the stop isn't a thing you bolt on after sizing. It's the input to sizing. Pick the stop where it makes sense on the chart, then let the size follow.
Move stops to protect, never to "give it room"
One rule to tattoo on your brain: you may only ever move a stop in the direction that reduces your risk.
- Trade goes your way? Fine to trail the stop up behind price to protect gains.
- Trade goes against you and you're tempted to move the stop further away to avoid getting hit? That's not risk management. That's you re-deciding the trade in the exact panicked state you set the stop to protect you from. "Giving it room" is how a 1% loss becomes a 10% loss.
The pre-set stop only works if it's non-negotiable in the losing direction. Widen it once and you've thrown away the whole system.
Risk-reward ratio and the win rate you actually need
Risk-reward (R:R) compares what you risk to what you're targeting. Risk 100 to make 300 = a 3:1 trade. Your stop distance is the "1"; your target distance is the "3".
The point of R:R: you don't need to be right often to be profitable. Break-even win rate depends only on your R:R:
break-even win rate = (1) / (1 + R:R)
| Reward : Risk | Win rate needed to break even |
|---|---|
| 1 : 1 | 50% |
| 2 : 1 | 33% |
| 3 : 1 | 25% |
| 5 : 1 | 17% |
At 3:1 you can be wrong three times out of four and still not lose money. This is why pros obsess over target-to-stop distance instead of trying to be right every time. Fees and slippage nudge the real number up a little, so give yourself margin above the table.
Where to actually place the stop (structure, ATR, time)
Three common, defensible methods:
- Structure-based: put the stop just beyond a level the market respects: below a recent swing low (for longs), above a swing high (for shorts). Logic: if price breaks that level, your trade idea is simply wrong, so you want to be out.
- Volatility-based (ATR): ATR (Average True Range) measures how much an asset typically moves per candle. Place the stop something like 1.5-2× ATR away from entry so normal wiggle doesn't stop you out, but a real move does. Great for volatile crypto where a fixed dollar stop is too tight one week and too loose the next.
- Time-based: if the trade hasn't done what you expected within a set window, you exit regardless of price. Dead money is still risk (funding, opportunity cost).
Avoid the rookie move: placing the stop at a round dollar amount you're "comfortable" losing, ignoring the chart. The market doesn't know or care about your comfort level. It reacts to structure.
Trailing stops, break-even stops, and scaling out
Ways to manage a winner without abandoning the plan:
- Break-even stop: once price has moved a decent distance in your favour, move the stop up to your entry price. Now the worst case is a scratch, not a loss. This is a protective move, so it's allowed.
- Trailing stop: the stop follows price at a fixed distance (or a set number of ATRs), locking in more as the trade runs, and never moving backward. It rides trends while capping the give-back.
- Scaling out: close part of the position at the first target, let the rest run with a trailed stop. You bank a guaranteed win and keep upside. Costs you nothing but max theoretical profit, and it's much easier to hold a runner when you've already been paid.
All three only ever tighten risk. None of them ever widens a stop.
A stop is a trigger, not a guarantee: slippage and gaps
Your stop-loss doesn't promise you that exit price. It promises that when price touches your level, an order fires. What fills is up to the market.
- Slippage: in fast moves, the next available price can be worse than your stop. A market-stop guarantees you get out but not at what price; a stop-limit guarantees the price but may not fill at all (leaving you in a losing trade). Know which one you're using.
- Gaps: price can jump straight past your level without trading there (over a weekend, on a news shock, or in a thin crypto pair at 3 a.m.). Your stop fills on the other side of the gap.
- High leverage makes this lethal. At 100x, a small adverse gap past your stop can push the position into liquidation before your exit fills. The higher the leverage, the more a "guaranteed" stop is really just a hopeful trigger. Size so that a bad fill still survives.
Quick knowledge check
When are you allowed to move a stop-loss? Only to reduce risk: trailing it in your favour or moving to break-even. Never further away.
At 3:1 reward-to-risk, what win rate do you need just to break even? 25%. You can lose three of four trades and still not be down.
Does a stop-loss guarantee you exit at that exact price? No. It's a trigger. Slippage and gaps mean the actual fill can be worse, especially at high leverage.
