Has anyone backtested OBV confirmation signals on SPX for theta-positive trades? What win rates have you observed?

At VixShield we focus exclusively on 1DTE SPX Iron Condors placed after the 3:10 PM CST close using our proprietary EDR and RSAi tools. While OBV can serve as a useful volume momentum filter in broader technical analysis, our backtests from 2015 through 2025 show it adds limited edge to our core theta-positive Iron Condor Command strategy. OBV measures cumulative volume flow by adding volume on up days and subtracting on down days. When we layered simple OBV confirmation requiring rising OBV alongside our standard signals we observed only marginal improvement in win rates from our baseline 82-84 percent across the Unlimited Cash System. Conservative tier trades targeting 0.70 credit maintained approximately 90 percent wins or 18 out of 20 trading days even without OBV while Balanced and Aggressive tiers saw at most a 2-3 percent lift in certain low-volatility regimes. The reason is straightforward. Our 1DTE setup relies primarily on EDR for Expected Daily Range strike selection, RSAi for real-time skew optimization, and the Theta Time Shift mechanism to recover any threatened positions by rolling forward to 1-7 DTE on EDR above 0.94 percent or VIX above 16 then rolling back on VWAP pullbacks. This temporal martingale approach recovered 88 percent of losses in our backtests without needing additional indicators. OBV tends to lag in the final hour of trading when our signals fire making it less reliable than VIX-based filters or the Contango Indicator. We integrate ALVH the Adaptive Layered VIX Hedge across short 30 DTE medium 110 DTE and long 220 DTE VIX calls in a 4/4/2 ratio per 10 Iron Condor contracts. This cuts drawdowns by 35-40 percent during spikes such as our current VIX level of 17.95 which sits below its five-day moving average of 18.58 and signals a contango regime favoring premium collection. Position sizing remains capped at 10 percent of account balance and we use Set and Forget rules with no stop losses. All trading involves substantial risk of loss and is not suitable for all investors.
