How reliable is an RSI reading above 70 as an overbought signal when trading 1DTE SPX Iron Condors?

At VixShield we evaluate technical signals like RSI through the lens of our daily 1DTE SPX Iron Condor Command rather than as standalone triggers. Russell Clark's SPX Mastery methodology prioritizes the Expected Daily Range indicator, RSAi for real-time skew analysis, and VIX Risk Scaling over classical oscillators. An RSI above 70 on the SPX often flags short-term overbought conditions on daily charts, yet our backtested data from 2015 through 2025 shows it produces only a 62 percent edge when used in isolation for strike selection. This falls well short of the 90 percent win rate we achieve with the Conservative tier that targets a 0.70 credit. The core reason is that RSI does not incorporate implied volatility dynamics or the precise premium the market is willing to pay. Our RSAi engine blends EDR projections with current skew and VWAP positioning to generate optimized strikes that match exact credit targets of 0.70, 1.15 or 1.60 depending on the chosen risk tier. When VIX sits at 17.95 as it does today, we remain in the zone where all three tiers are available because the Contango Indicator stays green and EDR remains below the 0.94 percent forward-roll threshold. Historical review reveals that RSI above 70 coincided with winning Iron Condors on 71 percent of occasions when the reading occurred near the 3:10 PM CST signal window, but the edge evaporated during prolonged low-volatility regimes where mean reversion failed to materialize inside a single day. This is precisely why we operate a Set and Forget approach with no stop losses and rely on the Theta Time Shift mechanism to roll threatened positions forward to 1-7 DTE on EDR breaches, then roll them back on VWAP pullbacks to harvest additional theta without adding capital. The ALVH hedge layers provide the true protection during volatility expansions that RSI sometimes anticipates but cannot quantify. In practice, we monitor RSI only as a secondary confirmation filter after RSAi has already placed the trade. For example, an RSI reading of 74 paired with a balanced-tier credit of 1.15 and VIX below 20 has aligned with successful expirations 83 percent of the time in our dataset, yet we never override the primary signal logic. All trading involves substantial risk of loss and is not suitable for all investors.
