When trading SPX European-style options in an iron condor, how do you decide which in-the-money strikes to avoid at entry given the cash settlement feature?

At VixShield we approach every 1DTE SPX Iron Condor with precision because SPX options are European-style and cash-settled at expiration. This means there is no early assignment risk yet the final settlement value is determined by a special opening quotation calculated from the opening prices of the S&P 500 component stocks on expiration day. That reality shapes exactly how we select strikes each afternoon at our 3:10 PM CST signal. Our core methodology relies on the Expected Daily Range indicator, RSAi skew analysis, and three fixed credit tiers: Conservative targeting $0.70, Balanced targeting $1.15, and Aggressive targeting $1.60. These credits are collected by selling an out-of-the-money call spread and an out-of-the-money put spread that remain outside the projected settlement range. We deliberately avoid any short put strike that sits inside the current SPX price or within roughly 0.3 percent of it because cash settlement can produce unexpected pin risk near the money. For example with SPX at 7138.80 and VIX at 17.95 our EDR might project a daily range of plus or minus 83 points. We therefore place the short put leg at least 90 to 110 points below the close depending on the tier and the RSAi output. This keeps the short put out-of-the-money at entry and reduces the chance that an overnight gap or opening auction settles the position against us. The long put wing is then set another 50 to 75 points lower to define our maximum risk. On the call side we mirror the process above the expected upside. Because we use the Adaptive Layered VIX Hedge on every position the portfolio remains protected even if volatility expands and pushes price toward our wings. Our Set and Forget rules mean we never adjust or stop out an individual trade. Instead the Theta Time Shift mechanism allows any challenged position to be rolled forward temporarily during elevated VIX readings above 16 and then rolled back once EDR drops below 0.94 percent and price trades under VWAP. This temporal recovery has historically turned the majority of apparent losers into net winners without adding capital. Cash settlement therefore does not change our entry discipline it simply reinforces the need for disciplined distance from the spot price and reliance on EDR and RSAi rather than arbitrary round numbers. Traders who chase higher credits by moving short strikes too close to the money often discover on expiration that the cash-settled index prints inside their short strike even though intraday price action looked safe. We avoid that entirely by letting the proprietary indicators choose the exact wings that match our chosen credit tier while maintaining at least a 1.0 percent buffer from spot on both sides in normal contango environments. All trading involves substantial risk of loss and is not suitable for all investors.
