When the price touches the stop-loss or take-profit price set by the client, the system will then send a close-out order and match the relevant close-out orders according to the engine’s price instantly. PGM prices are executed at the best available price. If there is a shortfall due to price fluctuations or if the expected matching price cannot be found in the market, the system will execute at the next available price in the market, so there is a chance that the transaction price will break through the Stop Loss or Take Profit price.
