Stop-loss placement: structure, volatility and time-based methods

A stop-loss is not a maximum acceptable loss; it is the price at which your reason for the trade is no longer valid. Placing it based on how much you are willing to lose guarantees that ordinary noise removes you from good positions.

Structural placement puts the stop just beyond the swing low, the range boundary or the level whose breach kills the idea. Position size then adapts to the distance — not the other way round.

Volatility-based placement scales the distance to current conditions, commonly a multiple of average true range. This automatically widens stops in volatile weeks and tightens them in quiet ones, which prevents the classic mistake of using the same distance in every environment.

Time stops are underused. If a trade has not worked within a defined number of sessions, exit. Capital and attention are finite, and dead positions consume both while offering nothing.
