A forex stop order is an order given to a broker to liquidate a trade at a specified price. If the market price of a currency pair drops below the specified price, the trade would be immediately closed. Unfortunately, in certain circumstances, the stop order may disappear from the platform before it can be filled. This could be due to technical glitches, platform malfunctions, or other unpredictable market events. As such, it is important to understand the reasons why a stop order may not be executed in order to maximize profits and minimize risks when trading in the Forex market.
