The Seatbelt Analogy
You don't wear a seatbelt because you expect to crash today — you wear it because if you do crash, the damage is contained instead of catastrophic. A stop-loss (SL) works exactly the same way: it doesn't predict the trade will fail, it simply ensures that if it does, the loss is small and defined rather than open-ended.
What Is a Stop-Loss?
A stop-loss is a pre-decided price at which you exit a losing trade automatically, cutting further losses. It should be decided before entering the trade — not adjusted emotionally while the trade is running against you ("just a little more room, it'll bounce back").
Where to Place a Stop-Loss
- Below a recent swing low (for a long/buy trade) or above a recent swing high (for a short/sell trade) — using the support/resistance memory from Level 4.
- Beyond the expected normal "noise" of the instrument, so the stop isn't triggered by ordinary volatility.
- Never so wide that a single stop-out breaks your 2% risk cap (Chapter 1) — if the "correct" technical stop is too far away, the fix is a smaller position size, not a wider risk budget.
