How a Stop Loss Works
When you open a trade you also place a stop order at a price beyond your entry — below it for a long, above it for a short. If price never touches that level, nothing happens. If it does, the stop triggers and your position closes at (or near) that price. You're out, the loss is booked, and your capital is free for the next setup.
There are two flavors worth knowing. A stop-market order closes you at the next available price once triggered — guaranteed fill, but in a fast crypto wick you can get a worse price than the level you set (slippage). A stop-limit order only fills at your specified price or better, which protects you from slippage but risks not filling at all if price gaps straight through. On thin alt pairs and during liquidation cascades, that distinction costs real money.
| Stop-Market | Stop-Limit | |
|---|---|---|
| Fill guaranteed? | ✅ Yes — fills at next price | ❌ No — may not fill at all |
| Slippage risk | ⚠️ Yes — worse price on a fast wick | ✅ None — fills at your price or better |
| Gaps straight through? | ✅ Still closes you | ❌ Can leave you in the trade |
| Best for | Getting out no matter what | Liquid pairs, price control |
| Risk on thin alts | Worse fill, but you are out | You may stay stuck in the loss |
Why Traders Skip It — and Pay
The stop loss isn't a technical problem. It's an emotional one. Placing the order is easy. Watching price approach it and not canceling it is where accounts die.
The classic sequence: you're long, price drops toward your stop, and a voice says "it'll bounce, I'll just give it a little more room." You drag the stop lower. Price keeps falling. You drag it again. What was a planned 1% loss is now 8%, and you're holding a position you no longer believe in purely because closing it means admitting you were wrong. This is how a disciplined trader becomes a bag-holder in the space of one afternoon.
The cost compounds. One un-stopped loss can erase the profit from your last ten clean trades. A 50% drawdown needs a 100% gain just to recover — the math is brutally asymmetric, and a violated stop is the fastest way into it.
How to Set One Properly
Place your stop where the trade idea is invalidated — below the structure, the swing low, the level that, if broken, means your read was wrong. Then size the position so that distance equals a fixed, small share of your account. Don't pick the stop to fit the size you want; pick the size to fit the stop the chart demands. That's the link between this and position sizing: the stop sets the risk per unit, the position size sets how many units, and together they cap your dollar loss.
The one rule that matters: a stop only moves in your favor. You can trail it up to lock in profit. You never move it away to avoid a loss.
Account is $10,000, you risk 1% ($100) per trade. You go long at $100 with a stop at $96 — a $4 risk per coin. $100 ÷ $4 = 25 coins.
If the stop hits, you lose $100, exactly as planned, regardless of how violent the move was. Run the numbers with a position size calculator before you enter.
Pick the size to fit the stop, never the stop to fit the size. The chart decides where the stop goes; your risk budget decides how many units you can hold behind it.

How a Journal Exposes Stop-Loss Leaks
You can believe you respect your stops while your fills tell a different story. A journal settles the argument. Tradermake.money imports every trade from your exchange automatically, so it sees the exits you actually took — not the ones you meant to take.
When your average loss runs bigger than your planned risk, that gap is visible, trade by trade. The AI coach flags the pattern directly: the trades where you widened a stop, the days your losses cluster, the difference between your intended 1% and the real number bleeding off your equity. You can't fix a leak you can't see.
