Penetrate multi-terminal execution barriers and use integrated hardware ecology to reconstruct micro-management efficiency! This article provides in-depth science knowledge on the underlying technical support of global mainstream MT4/MT5 terminals in quantitative EA intelligent algorithms and strategy backtesting. Comprehensively dismantle the risk control model that synchronizes real-time quotes of multiple categories on the mobile terminal, and automatically locks floating profits with trailing stops. It also takes a cold-eye view of the historical performance lag and slippage risks of cross-account copying in social copying, helping you to establish an institutional-level full-link risk control mechanism.
