Managing Stop Loss

A standard stop loss becomes a market order once the trigger price is reached, meaning it then fills at the next available price, which can be worse than your trigger level in fast or thin markets. This difference between the trigger and the fill is often called slippage. Price gaps, for example when a market opens far from its previous close, can also cause a stop to execute well beyond the level you set. Some brokers offer variations such as stop-limit orders, which convert to a limit order instead and may not fill at all, or guaranteed stops, which typically carry an extra cost and specific conditions. Whether these variants exist, how they behave and what they cost differs by broker and product, so confirm the details in your broker's current order execution documents rather than assuming.

There is no single correct stop placement, but common approaches share a theme: the stop should reflect a level at which your original reason for holding the position no longer holds, rather than an arbitrary round number. Some investors size the stop distance from recent price ranges or volatility so that normal fluctuations are less likely to trigger it; others place stops beyond technical levels they consider meaningful. Position sizing works alongside placement: a wider stop generally implies a smaller position if you want to cap the potential loss at a fixed portion of your account. Trailing stops, where available, move the trigger level as the price moves in your favour, which can help protect gains but can also be triggered by ordinary pullbacks. Whatever method you choose, decide it before entering the trade and avoid widening a stop after the fact simply to avoid taking a loss.

Because execution behaviour differs between brokers and instruments, read your broker's order execution policy and product terms before treating a stop loss as your safety mechanism. Confirm which stop order types are actually available on the instruments you trade, whether stops remain active outside regular trading hours, how the broker handles gaps and fast markets, and whether any guaranteed-stop facility exists, along with its costs and conditions. For leveraged products such as CFDs, also understand how stops interact with margin requirements and forced position closures, since leverage magnifies both gains and losses.
