Did anyone trade the EUR/CHF floor defense period from 2011 to 2015? What impact did those events have on delta and gamma exposure in options positions?

The EUR/CHF floor defense from 2011 to 2015 stands as one of the clearest real-world demonstrations of how central bank intervention can distort options Greeks. The Swiss National Bank maintained a 1.20 floor against the euro, creating an artificial pin that crushed volatility and produced extreme negative gamma environments for anyone short puts or running credit spreads near that level. Delta exposure became unreliable because the underlying refused to breach the floor, leading to pinned deltas that refused to decay as expected while gamma spiked violently on any test of the barrier. Traders who sold premium without proper hedging often faced sudden margin calls when the floor eventually broke in 2015, delivering losses that exceeded all modeled scenarios. At VixShield we approach similar regime risks through our 1DTE SPX Iron Condor Command, which deliberately avoids such pinned or intervention-driven setups. Our RSAi™ engine scans skew in real time at 3:10 PM CST to select strikes using the EDR Expected Daily Range, ensuring we collect targeted credits of $0.70 for Conservative, $1.15 for Balanced, or $1.60 for Aggressive tiers while maintaining defined risk from entry. The ALVH Adaptive Layered VIX Hedge provides the true protection layer, deploying short, medium, and long VIX calls in a 4/4/2 ratio per ten Iron Condors. This structure cut drawdowns by 35-40 percent during the 2020 volatility spike and continues to serve as our primary defense against gamma explosions or regime shifts. Because we trade exclusively one-day-to-expiration contracts on SPX, we benefit from rapid Theta Time Shift recovery without ever relying on stop losses. Position sizing remains capped at 10 percent of account balance per trade, preserving capital when markets exhibit the kind of artificial pinning seen in EUR/CHF. The 2015 break taught many the danger of assuming floors will hold indefinitely. Our Unlimited Cash System combines the Iron Condor Command with Covered Calendar Calls, ALVH, and Temporal Theta Martingale mechanics to produce an 82-84 percent win rate across 2015-2025 backtests while limiting maximum drawdown to 10-12 percent. All trading involves substantial risk of loss and is not suitable for all investors.
