Where to Place Your Stop-Loss (Structure, Not Guesswork)
Set the stop first — at the price where your idea is proven wrong — then size the trade to it.
Yesterday: risk small and fixed. Today: where that risk actually lives — your stop-loss. Most traders pick a size first and jam a stop wherever the loss feels tolerable. That's backwards, and it's expensive.
Stops belong at structure, not round numbers
A good stop sits at the price where your reason for the trade is gone — not at an arbitrary dollar amount or a round number everyone else is watching.
For a long idea, that's usually below the swing low that has to hold. For a short, above the swing high. Place it far enough that normal market noise won't tag it, but no further — every extra bit of stop distance shrinks your position size for the same risk.
The discipline that matters most
Once the stop is set, you don't move it wider. Widening a stop to avoid a small loss is exactly how small losses become account-enders.
If price hits your stop, your idea was wrong — take the small, pre-defined loss and move on. Being willing to be wrong cheaply is the entire game. You set the stop before entry, when you're calm, precisely so you don't have to make that decision emotionally mid-trade.
