There's a fundamental difference between a trade and a bet: a trade has a plan. Before opening the position, you know where to exit if it goes bad (stop loss) and where to exit if it goes well (take profit). These two numbers aren't guesses — they're the result of a coherent method. This article shows you how to build this plan systematically.
Why a stop loss is non-negotiable
A stop loss is an automated order that closes your position if price reaches a certain adverse level. It's your safety net. Without it:
- You let losses run because "it'll come back";
- You take emotional positions that get worse over time;
- Your capital can disappear on a single mismanaged trade.
The rule is simple: no stop, no trade. Ever. No exceptions. Not for "just a tiny test trade", not for "a coin I believe in", not for anything. The stop is what separates a trader from a degen.
Where to place your stop loss
There are two approaches, to be combined.
Approach 1: the technical stop
Place your stop at a logical technical level — a place where your trade thesis would be invalidated if price reached it. Examples:
- Below the major support you entered on.
- Below the recent low (for a long).
- Below a trendline carrying the trend.
- Below a key Fibonacci level (e.g., 78.6%).
- Below an EMA acting as dynamic support.
The principle: if price breaks this level, your initial thesis is wrong. You exit and wait for a better setup.
Approach 2: the volatility stop (ATR)
Place your stop at 1.5 to 2 × ATR below your entry (for a long). This approach is statistical: it prevents normal market noise from exiting you. See ATR.
Combine both
Best practice: take the farther of the two.
- If technical stop is 2.5% and ATR stop is 1.8%, take 2.5% (respect technical level).
- If technical stop is 1.2% and ATR stop is 2%, take 2% (noise protection).
This rule avoids both stops that are too tight (exit on noise) and too wide (leave too much risk).
Stop loss pitfalls
Pitfall #1: stop at exact high/low. Never place a stop right at the pixel of recent low/high. Stop hunts (collective stop trigger on obvious level) are frequent in crypto. Place it just below/above the level, with small buffer (0.3-0.5%).
Pitfall #2: moving stop against you. You enter with 2% stop, price goes to -1.5%, you move stop to -3% "to give room". You just tripled your risk with no technical reason. Never do this. A stop moves only in your direction (trailing stop), never against.
Pitfall #3: forgetting the stop. In crypto, with 24/7, a stop must be placed on the exchange (stop order), not "mental". Otherwise you sleep and your position tanks. Put the real order.
Pitfall #4: stop invisible on obvious level. Everyone places stop below recent visible low. Market makers know this, and "stop hunt" moves are frequent. A stop slightly farther, or manual exit on confirmation, protects better than the "obvious" solution.
Take profit: the other half of the plan
Less discussed, often less respected, but equally important. A target defined before entry prevents you from:
- Letting gains run until they turn to losses;
- Taking profits too early from fear;
- Trading without horizon, making your stats useless.
Where to place your target?
A few approaches:
1. Technical target: the next significant resistance level. For example: you buy at $50,000 with stop at $48,500, your target is resistance at $54,000.
2. Pattern-projected target: if you have a pattern (head-shoulders, flag, triangle), the standard projection gives a theoretical target.
3. Risk/reward ratio target: you decide your minimum target is 2:1 or 3:1 against your risk. Stop at 1.5%, minimum target at 3% for 2:1, at 4.5% for 3:1.
4. ATR target: 3 to 5 × ATR above your entry (for a long). Statistically coherent with volatility.
Combine these approaches: your final target is the minimum between the nearest technical target and your minimum R/R target. If no technical level is reachable at a correct R/R ratio, maybe the trade isn't worth taking.
Partial exit vs full exit
A powerful practice: exit in tranches. Example:
- 50% of position at first target (profit "secured");
- 30% at second target;
- 20% on trailing stop to let it run.
This balances "taking gains" and "letting winners run". The remaining position after first exit costs zero — you only risk unrealized gains now, not initial capital. It's mentally far more comfortable, and lets you capture big moves without missing them.
The risk/reward ratio
This is the central metric. Before each trade, calculate:
R/R = (Target - Entry) / (Entry - Stop)
For a long. Inverted for a short.
Rule: don't take trades with R/R below 1.5:1, ideally 2:1 or higher. Why? Because with 2:1 ratio, you can lose 60% of trades and still break even. With 1:1 ratio, you need > 50% win rate to break even — far harder to sustain long-term.
R/R is your safety margin against recurring losses. Never compromise on it.
A complete trade plan
Before each trade, write (or mentally calculate) these 6 elements:
- Thesis: why enter? ("Bounce off 1D support + RSI divergence 4h + engulfing 1h.")
- Entry: exact entry price.
- Stop: exact stop price + distance in %.
- Target 1: exact price of first exit.
- Size: calculated from risk % and distance to stop.
- R/R: calculated and verified ≥ 2:1.
If any of these 6 is unclear, don't take the trade. It's not a trade, it's a bet.
In DYOR
DYOR includes a position sizer and displays auto-detected support/resistance levels, helping you:
- Instantly calculate position size for given risk;
- Identify technical levels for stops and targets;
- Track potential R/R before entering.
Use these tools instead of doing math in your head — they're more reliable and faster.
