Short-term market fluctuation in a stock's price can activate a Stop Limit Order, so trigger price and limit order price should be selected carefully.

For Stop Market orders, once the stop price is reached, the Stop order will be activated and becomes a Market order and the transacted price may be quite different from the stop price, especially in a fast-moving market or in a cascading price scenario where stock prices can change rapidly.

There will be no guarantee that the order will be filled in the event the price gaps through the limit price. In such an event, the order will not be filled.

Investors must take note that once the market-if-touched order is triggered, the order will be injected into the order book as a market order which comes with the associated risk of a market order. The use of a limit-if-touched order may reduce the risk of being filled at a too unfavourable price when the order is triggered.
