SEMI HFT EA v2.0 MT4 is likely a custom Expert Advisor designed for semi-high-frequency trading (HFT). This EA aims to execute trades at a much faster rate than regular trading strategies but typically does not operate at the ultra-fast pace that true HFT systems do, which often require sophisticated technology and low-latency connections. The "semi" part likely indicates that the EA operates with a moderate frequency of trades, as opposed to the lightning-fast, millisecond-based decisions of traditional HFT systems.
