PropFirm Equity Protector - Institutional Risk Manager (Open Source) - Asesor Experto para MetaTrader 5

🛡️ PropFirm Equity Protector (Institutional Risk Manager)

1. Recommended Symbol & Timeframe

• Symbol: Any (Highly recommended for volatile assets like XAUUSD, GBPUSD, or Indices such as US30).

• Timeframe: Any. This Utility EA is timeframe-independent because it relies on the OnTimer() event (1-second intervals) rather than OnTick() , ensuring constant risk monitoring even if the market freezes.

2. Core Ideas Deposited in the Code The primary idea behind this code is to provide an institutional-grade risk management framework for Prop Firm traders. Traditional Stop Losses are vulnerable to extreme slippage during news events. This EA mitigates that by introducing a Dual-Tier Risk Mitigation System:

• Tier 1 (Soft Limit): When the account reaches a warning drawdown level, the EA identifies the worst-performing open position and executes a partial close (e.g., 50% of the volume) to inject free margin back into the account and avoid a total breach.

• Tier 2 (Hard Limit): If extreme volatility pushes the equity to the absolute daily Prop Firm limit, the EA triggers an aggressive panic-close loop, bypassing broker requotes to secure the account.

3. External Variables Description

• InpMaxDailyLossPercent : The absolute maximum daily loss allowed by your Prop Firm (e.g., 4.5%). Triggers Tier 2.

• InpAutoCloseOnLimit : Enables the Tier 2 absolute panic close.

• InpRemoveEAOnLimit : If true, the EA detaches itself from the chart after a Tier 2 breach to block further automated trading.

• InpMitigationLossPercent : The warning threshold (e.g., 3.5%). Triggers Tier 1.

• InpEnableMitigation : Activates the Tier 1 partial closing module.

• InpPartialClosePercent : The percentage of the worst position's volume to close during Tier 1 mitigation (Default: 50.0).

• InpSlippagePoints : Allowed deviation to enforce closure in fast markets.

• InpSendPushNotification : Sends a mobile push alert upon limit breaches.

• InpMaxRetries : How many times the EA will force-send the close command if the broker server returns an error.

4. Brief Explanation of the Code Structure To help other users understand the implementation, this EA was developed using strict Object-Oriented Programming (OOP) principles.

• CPropFirmProtector Class: Encapsulates all risk logic, preventing global variable conflicts.

• CalculateDailyStartBalance() Method: Instead of relying on static variables, it scans the HistorySelect() from 00:00 server time to mathematically calculate the exact daily starting balance, accounting for swaps, commissions, and closed profits.

• Self-Healing GUI: The on-chart dashboard utilizes a Z-order locked background and a self-repairing loop ( ObjectFind ). If another indicator accidentally deletes the risk dashboard, the EA reconstructs it in a millisecond.
