Stop loss

An order that closes a trade at a set price to cap the loss. It marks the point where the trade idea is proven wrong.

Set it with the order, size the position from its distance, and never move it further away once you are in.

In practice

A signal buys GBP/USD at 1.2700 with a stop at 1.2660, 40 pips away. A trader risking $80 sizes the trade at 0.20 lots (40 × $10 × 0.20 = $80), so a stop-out costs exactly the planned amount.

Common mistake

Moving the stop further away as price approaches it. That turns a planned, small loss into an unplanned, large one.
