OPEN-SOURCE SCRIPT
Updated EvilAI | Survival Sizer
Position sizing that adapts to market conditions. Define how many losses you can survive — the indicator calculates optimal size using ATR and volatility regime detection.
█ FEATURES
- Survival-based sizing — set losses to endure, not arbitrary risk %
- Volatility-adjusted positions:
└─ LOW vol: Size ↑ (be aggressive when markets are calm)
└─ NORMAL: Baseline sizing
└─ HIGH vol: Size ↓ (get defensive when chaos rises)
└─ EXTREME: Size ↓↓ (protect capital at all costs)
- ATR + Historical Volatility combined for regime detection
- Auto contract selection (GC/MGC, NQ/MNQ)
- Color-coded risk warnings
█ DESIGNED FOR
Prop firm traders (FundedNext, Topstep, Apex) who need adaptive risk management. When volatility spikes, you automatically size down. When markets are calm, you can push harder. All while respecting your survival floor.
█ HOW IT WORKS
1. Set your daily drawdown limit ($2,000)
2. Set target survivable losses (10)
3. Indicator calculates: $2,000 ÷ 10 = $200 max risk per trade
4. ATR determines stop distance → position size
5. Volatility regime adjusts final size up or down
6. Auto mode selects micro vs full contracts
█ DISPLAY
- Compact mode: Contracts, risk, survival count, vol regime
- Full mode: Complete breakdown with percentiles
- Survival shows actual vs target (e.g., "12L / 10L")
█ COLOR CODES
- Green: Meeting or exceeding survival target
- Yellow: Close to target / capped at max
- Cyan: Boosted (low volatility)
- Purple: Reduced (high volatility)
- Red: Below target — reconsider your sizing
Stop blowing accounts. Size positions properly.
