Turning percentages into orders
Deciding "I'll cut it at 5%" is not a plan until it is a price. Converting the percentage into the number you will actually type into an order removes the moment of hesitation when the level arrives.
target price = entry × (1 + target %)
risk/reward = (target − entry) ÷ (entry − stop)
break-even win rate = 1 ÷ (1 + R)
What each ratio demands of you
| Risk / reward | Win rate needed to break even |
|---|---|
| 1 : 0.5 | 66.7% |
| 1 : 1 | 50.0% |
| 1 : 2 | 33.3% |
| 1 : 3 | 25.0% |
| 1 : 5 | 16.7% |
This is the table that settles most arguments about trading style. A high win rate with small targets and a low win rate with large ones can be equally profitable. What cannot work is a low win rate paired with small targets, which is where most losing accounts sit.
A worked example
0.25 coins entered at $42,000, with a 5% stop and a 15% target:
| Stop price | $39,900 |
|---|---|
| Target price | $48,300 |
| Loss if stopped | −$525.00 |
| Profit at target | $1,575.00 |
| Risk / reward | 1 : 3 |
This setup can be wrong three times out of four and still not lose money.
Where to actually put the stop
A round percentage is convenient but arbitrary. A stop belongs at the price that would prove the idea wrong — below the structure you entered on, outside the range of ordinary noise for that asset. Then let that distance size the trade rather than the other way round, using the position size calculator.
- Avoid the obvious level. Stops cluster just under round numbers and recent lows, and clusters attract the moves that trigger them.
- Scale the distance to volatility. A 2% stop on a large-cap is reasonable. The same stop on a small-cap that routinely swings 8% in a day is a donation.
- Do not widen it mid-trade. Moving a stop further away converts a defined loss into an open-ended one, which is the single most reliable way to damage an account.
- Trail with a rule, not a feeling. Moving the stop to break-even after a defined gain is a plan. Moving it because you are nervous is not.
Common questions
How do I set a stop loss in crypto?
Decide the price that would prove your reason for entering wrong, place the stop just beyond it, and then size the position so that being stopped out costs only what you can accept.
What is a good risk-reward ratio?
1:2 or better is a common benchmark, because it lets you be wrong more often than right and still profit. The ratio only matters alongside a realistic estimate of your win rate.
What win rate do I need to be profitable?
Divide one by one plus your risk-reward ratio. At 1:3 you need to win a quarter of your trades to break even, before fees.
Should I use a percentage-based stop?
It is a reasonable starting point but arbitrary. Stops placed at structural levels and scaled to the asset's volatility survive ordinary noise better.
Can I move my stop loss?
Moving it in your favour as a trade works is a legitimate technique. Moving it further away to avoid being stopped out turns a planned loss into an unplanned one.
