SPX 2-4-4 Put Ratio Strategy Official Rules & Playbook
Authoritative strategy guide for scanning, sizing, stress testing, and managing SPX 2-4-4 put ratio structures.
1. Strategy Structure & Leg Mechanics
+2 Leg 1 Puts (~30Δ) / -4 Leg 2 Puts (~18Δ) / +4 Leg 3 Puts (~3Δ)
Decomposed into 2 Upper Put Debit Spreads (+2 K1 / -2 K2) plus 2 Lower Put Ratio Credit Spreads (-2 K2 / +4 K3). Target DTE: 52 DTE (Window: 45 to 60 DTE).
2. Core Governance Criteria & Filter Limits
| Parameter | Target / Rule Boundary | Action on Breach |
|---|---|---|
| Entry DTE Window | 52 DTE Target (Allowed: 45 – 60 DTE) | Reject if DTE < 45 or DTE > 60 |
| Leg 1 Delta ($K_1$) | Target: -0.30 (Range: -0.24 to -0.36) | Skip strikes outside window |
| Leg 2 Delta ($K_2$) | Target: -0.18 (Range: -0.14 to -0.24) | Skip strikes outside window |
| Leg 3 Delta ($K_3$) | Target: -0.03 (Range: -0.01 to -0.04) | Skip strikes outside window |
| Net Position Delta (Δ) | -2.0 ≤ Δ ≤ +2.0 | Hard Reject if |Δ| > 2.0 |
| Net Position Theta (Θ) | Θ > 0.0 / day (Positive Decay) | Hard Reject if Θ ≤ 0 |
| Entry Premium Capping | ≤ 10.0 SPX Points (≤ $1,000 net price) | Hard Reject if |Net Price| > 10.0 pts |
| Down 1% / IV +2 Stress | Loss < 1.5% of Buying Power | Hard Reject if Stress Loss > 1.5% BP |
3. Mechanical Position Management & Exit Rules
Take Profit Target (+2.0% Buying Power)
Submit limit order to close all 3 legs (+2 K1, -4 K2, +4 K3) as soon as position net profit reaches +2.0% of position Buying Power.
Stop Loss (-3.0% Buying Power)
Close entire trade immediately if mark-to-market loss reaches -3.0% of position Buying Power to prevent short leg gamma expansion.
Soft Exit Window (~23 DTE)
Evaluate daily at 23 DTE. If profit target is close or market volatility expands, close position early.
Mandatory Time Exit (20 DTE)
MANDATORY: Close all 3 legs at 20 DTE regardless of P/L. Never hold past 20 DTE due to accelerating short gamma.
4. Multi-Index Parameter Calibration (SPX, RUT & NDX)
| Parameter | SPX (S&P 500) | RUT (Russell 2000) | NDX (Nasdaq-100) | Rationale |
|---|---|---|---|---|
| Index Spot Scale | ~7,400 pts | ~2,940 pts | ~20,150 pts | Underlying spot benchmark across indices. |
| Max Entry Premium | ≤ 10.0 pts | ≤ 6.0 pts | ≤ 35.0 pts | Scaled proportionally to ensure low capital outlay on entry. |
| Est. Buying Power Requirement | ~$25,000 | ~$15,000 | ~$85,000 | Standard portfolio margin requirement for ratio structure. |
| Strike Grid Step | 5.0 pts | 5.0 pts | 25.0 pts | Liquid option chain intervals. |
| Volatility Index | VIX | RVX | VXN | Index-specific benchmark for market environment filters. |
| Option Roots | SPX / SPXW | RUT / RUTW | NDX / NDXP | European cash-settled contracts with zero assignment risk. |
