How do triggers work when activating pending orders?

Triggers execute pending orders once the market reaches a specified price. Sudden price movements may activate them differently than expected. The mechanism itself is straightforward. The platform continuously compares real-time market prices against the trigger levels set by the trader, and the moment the market reaches or crosses the specified price, the pending order is activated and sent for immediate execution at the best available price.

The activation process differs slightly depending on the order type. For buy stop and sell stop orders, the trigger activates when the market moves through the specified level in the direction of the anticipated trade — signalling a breakout or continuation that the trader wants to capture. For buy limit and sell limit orders, activation occurs when the market retraces to a more favourable price level that the trader has identified as a desirable entry point. In each case, the trigger serves as the precise mechanism that converts a passive pending instruction into an active market order, ensuring the trader's strategy is executed at the intended level without manual intervention.

However, it is important to understand that real market conditions can affect how triggers behave in practice. During periods of extreme volatility — such as around major economic data releases, unexpected geopolitical events, or at market open after a weekend — prices can move very rapidly or gap from one level to another without trading at intermediate prices. In these situations, a trigger may be activated at a price different from the originally specified one, resulting in slippage between the intended and the actual execution price. This is a normal aspect of live market trading and applies across all platforms and instruments. To manage this risk, traders should avoid placing triggers at levels extremely close to the current market price during volatile periods, consider using limit-based orders where appropriate to set the maximum acceptable execution price, and regularly review their pending orders ahead of scheduled high-impact events.
