Does the bid-ask spread on SPX options consume enough of the edge that carry-style strategies cease to be effective?

At VixShield, we trade 1DTE SPX Iron Condors exclusively using the Iron Condor Command placed after the 3:09 PM CST SPX close. The bid-ask spread on SPX options is a legitimate concern for any carry-style approach, yet our methodology accounts for it directly through disciplined strike selection and premium targets that preserve a positive edge. SPX options are among the most liquid in the world, with tight spreads typically ranging from $0.10 to $0.30 on the wings we target. Our Conservative tier seeks a $0.70 net credit, Balanced targets $1.15, and Aggressive aims for $1.60. After subtracting average slippage of roughly $0.15 to $0.25 per contract on a four-leg iron condor, the net credit remains sufficient to support our documented win rates. The Conservative tier, for example, has achieved approximately 90 percent wins, or 18 out of 20 trading days, precisely because RSAi™ rapidly analyzes skew and pairs it with the EDR indicator to place strikes where the market is actually paying the desired premium. This precision minimizes the impact of the spread compared with discretionary entries. Our Set and Forget methodology reinforces this edge by eliminating intraday management and stop losses. We define risk at entry, size positions to a maximum of 10 percent of account balance, and rely on the Theta Time Shift recovery mechanism to handle the infrequent losers without adding capital. When volatility expands, the ALVH Adaptive Layered VIX Hedge provides protection across three timeframes in a 4/4/2 ratio, cutting drawdowns by 35 to 40 percent at an annual cost of only 1 to 2 percent of account value. The After-Close PDT Shield timing further protects retail accounts from pattern day trader restrictions while allowing us to harvest the overnight theta decay that forms the core of our carry. In backtested results from 2015 through 2025, the Unlimited Cash System combining these elements delivered 82 to 84 percent win rates and 25 to 28 percent CAGR with maximum drawdowns of 10 to 12 percent. The bid-ask spread does reduce gross edge, but our systematic process using EDR, RSAi™, and VIX Risk Scaling ensures the net edge remains intact and repeatable. All trading involves substantial risk of loss and is not suitable for all investors.
