A trailing stop sounds simple: let the market move in your favor, then trigger an exit only after price reverses by a chosen distance. Kraken describes trailing stop sell orders as following the market upward and triggering after a decline from the highest price after entry. Interactive Brokers presents the same idea across stocks, options, futures and forex.
The risk is that the trigger is not the fill. Once the stop activates, the order still meets the live order book. In fast crypto markets, a small callback can trigger during noise. In stocks or futures, overnight gaps can skip past the intended exit area. In perpetual contracts, mark-price versus last-price rules can change when the order wakes up.
A practical framework is to match the trail to volatility. Very tight trails fit scalps but can be shaken out. Wider trails fit swing trades but give back more open profit. Traders should also decide whether the triggered order becomes a market order or a limit order, because that choice trades fill certainty against price control.
Trailing stops work best as part of a position plan: entry reason, invalidation level, position size, liquidity check and maximum account loss. They should not be used as a substitute for sizing discipline.

Risk notice: Stop and trailing orders do not guarantee exit price. Gaps, liquidity shortages and platform settings can produce losses larger than expected.
