Guaranteed Stop Loss

What Guaranteed Stop Loss means

An ordinary stop loss becomes a market order when triggered, so a gap can produce a fill far worse than the level. A guaranteed stop loss order removes that risk: the broker undertakes to close the position at precisely the specified price regardless of where the market actually traded, absorbing the difference itself. This turns the maximum loss on a trade into a genuinely known number, which is why guaranteed stops are used around scheduled events, over weekends, and on instruments prone to gapping.

Brokers charge for the protection. The usual structures are a premium added to the spread when the order is placed, a separate per-trade charge proportional to the notional, or a wider spread on a dedicated limited-risk account. Many brokers refund the premium if the guaranteed stop is never triggered, but this is a commercial choice rather than a standard, so the terms should be read. There is normally a minimum distance from the current price, often expressed in points or as a percentage, and guaranteed stops are typically unavailable on the most volatile instruments or immediately before major data.

Availability is also jurisdictional. Guaranteed stops are common among brokers serving the United Kingdom, Europe and Australia, where limited-risk accounts are a familiar retail product, and they are far less common elsewhere. They should not be confused with negative balance protection, which caps total losses at the account balance across all positions rather than fixing the exit price on any single one. The two solve different problems, and a trader can have the second without the first. Traders should also verify whether the guarantee survives a trading halt or a suspended instrument, since some terms exclude those cases explicitly.
