Vega Risk Shield — User Guide
1. Overview
Vega Risk Shield EA is a risk-focused Expert Advisor for MetaTrader 5.
Its core purpose is to protect trading equity by combining:
• ATR-based SL/TP management
• Dynamic Position Sizing (risk % or fixed lot)
• Equity Guard (daily loss limit, max drawdown, minimum equity)
It can run in Risk Manager mode only (default) or trade automatically using a simple ATR
Channel Breakout strategy.

ATR Channel Breakout Mode

• If price > upper channel → Buy.
• If price < lower channel → Sell.
• Lot size, SL, and TP calculated dynamically based on risk settings.
4. Equity Guard Rules

o Equity < MinEquityToTradeo Daily loss ≥ MaxDailyLossPct
o Drawdown ≥ MaxDrawdownPct
• Panel shows status: OK or BLOCKED.
