BSS Scalping EA v1.4 MT4 works on based on HFT (high frequency trading) algorithm. Its mean trades average holding time remains in seconds. EA put two stop orders 1 buy stop and 1 sell top at near current price. And these two stop orders frequently keep modifying at predefined timer in seconds at predefined distance from current price. And during news events and sudden high volatility events EA took these orders into trades. And while a stop order becomes a trade after it second stop order deleted and trailing stop function started.
