Take absolute control of your portfolio's exit strategy with Peak-to-Valley Profit Preserver EA. Designed as a utility expert advisor, this tool continuously monitors your account's aggregate open positions and pending orders, executing an institutional-grade, mathematical exit sequence based on your strategy's historical MAE (Maximum Adverse Excursion) and MFE (Maximum Favorable Excursion) metrics, computed from "SQXHK Hourly PnL Analyser for VaR 及 CVaR 估算" offered during SQXHK StrategyQuant MasterClass lesson.

Whether you trade ranging market, breakout market, trending market or a combination of them, Profit Preserver EA acts as your ultimate automated circuit breaker—securing profits precisely when your statistical targets are reached and safely flatlining the account.

💎 Key Features

• Advanced MAE/MFE Exit Matrix: Calculates exact profit target using the historical performance (MAE/MFE) metrics of your strategies portfolio.

• Auto or Custom Equity Baselines: Automatically locks in your starting equity at launch, or allows you to specify a fixed dollar baseline.

• Smart Alert Throttling: Prompts real-time platform alerts if your running portfolio P/L breaches your specified MAE or MFE levels, using built-in timers to prevent alert flooding.

• Full Housekeeping Control: Configurable choices to close all active open positions, purge left-over pending orders, or both.

• Terminal Hard-Stop: Safely kills a global trading flag and shuts down the entire MetaTrader 5 terminal process after execution to prevent unwanted re-entries by other bots.

• Remarks: The Profit Preserver EA will ONLY hard-stop your MT5 terminal when the profit target is reached. It WILL NOT stop your MT5 terminal when account equity falls below designated MAE level but WILL only produce notification.

📐 The Execution Formula

The EA implements a strict statistical matrix. It treats both input metrics as absolute values to find your portfolio's expected volatility band, then applies an optional percentage buffer:

Target P/L = (1 + Percentage%) * (Portfolio MAE + Portfolio MFE)

Once your account's running open P/L matches or exceeds this target, the exit routine triggers instantly, terminating your MT5 terminal at the end.

⚙️ Input Parameters Explained

Core Settings & Housekeeping

• Enable Take Profit ( InpEnableMaeMfeTakeProfit ): Activates the automated formula-based mathematical exit loop.

• Additional Percentage ( InpAdditionalPercent ): Add a padding percentage on top of the calculated MAE+MFE baseline target.

Timing & Loop Thresholds

• Evaluation Interval ( InpCheckIntervalSeconds ): How frequently (in seconds) the EA recalculates the equity and profit math (Timer-based loop independent of tick volume).
