VixShield Proprietary — From SPX Mastery by Russell Clark
This term is part of the proprietary VixShield methodology developed by Russell Clark, FNP-C — author of the SPX Mastery series.
Definition
The core daily income strategy of the SPX Mastery system. A neutral four-leg options setup (bull put spread + bear call spread) on SPX, placed in the 15-minute post-close window using EDR-guided strike selection. Designed for 1DTE (one day to expiration) trades that profit from SPX staying within a defined range, with three risk tiers (High/Medium/Low) producing 78–85% win rates in 2015–2025 backtests.
Formula / Rules
Upper Breakeven = Upper Inner Strike + Net Credit
Lower Breakeven = Lower Inner Strike − Net Credit
Credit tiers: High $1.30–$2.85 | Medium $0.75–$1.30 | Low $0.55–$0.95
How It Works
Iron Condor Command places 1DTE iron condors on SPX each trading day in the 15-minute post-close window (after 4:00 PM ET). The pre-close scan (5–15 min before close) checks VIX level, EDR output, Expected Move, news headlines, and VWAP position. Based on this scan, the appropriate tier is selected: High for calm/wide markets (VIX < 15), Medium for normal conditions, Low for elevated VIX (15–20) or uncertain setups. Positions are sized at 1 contract per $25,000 of account value, with a maximum of 20 contracts. The strategy uses $2.00 stops to cap losses at $200/contract. Combined with ALVH hedging and Theta Time Shift recovery, the effective win rate rises to 82–84%.
