Mouse calculation: Quick P/L previews and break-even insights for MT5 traders

In this Mouse calculation review for 2025 the performance analysis focuses on decision support rather than automated order generation. Mouse calculation equips traders with instant per-order and aggregated P/L previews and highlights the basket break-even price so outcomes are visible before executing closes. The indicator is not an entry system; it is a management overlay that speeds up judgment calls when dozens of orders are active. What makes Mouse calculation unique is its simple, mouse-driven interface and inclusion of swap in P/L previews, giving realistic net figures. The underlying algorithm reads visible orders and calculates profit and loss for each trade and for the entire basket at the pointed price level. Time_Sync_Lines and break-even visualization help compare identical times across recent days, useful for pattern recognition. Shi Jie He designed the tool specifically for MT5, prioritizing low-latency calculations and chart overlay clarity. Mouse calculation performs best in environments where traders run multiple simultaneous entries, such as grid strategies or phased scaling. Risk management remains manual: the indicator informs where break-even sits and how much closing subsets of orders changes exposure. Expected performance characteristics center on improved execution timing and reduced decision errors rather than increased win rate; traders typically reduce unnecessary closures and improve capital efficiency when using Mouse calculation as part of a broader strategy.
