What is the best approach to trading Christmas Tree spreads for moderate bullish moves, and how should traders select the appropriate strikes?

Christmas Tree spreads are a multi-legged options strategy typically constructed with calls to express a moderate bullish outlook while benefiting from limited risk and defined reward. The structure generally involves buying one lower-strike call, selling two middle-strike calls, and buying one higher-strike call, all with the same expiration. This creates a payoff that peaks at the middle strikes and tapers off beyond the wings. Selection of strikes is critical and relies on expected price movement, implied volatility, and time to expiration. Generally, traders choose the body of the tree near or slightly above the current underlying price to align with a moderate bullish bias, with wings spaced to balance premium received against maximum potential gain. At VixShield, we approach all options strategies through the lens of Russell Clark's SPX Mastery methodology, which emphasizes 1DTE SPX Iron Condor Command trades placed daily at 3:05 PM CST after the cash close. This Set and Forget approach avoids active management, stop losses, or discretionary adjustments in favor of systematic rules based on EDR, RSAi, and VIX Risk Scaling. While Christmas Tree spreads fall outside our core daily income system, the same disciplined strike selection principles apply. Our proprietary EDR indicator forecasts the Expected Daily Range by blending short-term implied volatility from VIX9D with historical volatility, generating High, Medium, and Low strike recommendations that align with Conservative, Balanced, or Aggressive credit targets of approximately 0.70, 1.15, and 1.60 respectively. RSAi then refines these by analyzing real-time skew and VWAP to ensure the position captures the precise premium the market offers. For a moderate bullish Christmas Tree on SPX, one might anchor the long lower call near the lower EDR boundary, center the short calls around the expected moderate upside target, and place the highest wing at roughly 1.5 to 2 times the EDR projection to cap risk. With current VIX at 17.95 and SPX near 7138.80, an EDR around 1.16 percent suggests roughly 83-point daily moves, guiding strike spacing in five- or ten-point increments typical for SPX. The ALVH hedge remains our primary volatility protection across all positions, layering short, medium, and long-dated VIX calls in a 4/4/2 ratio to cut drawdowns during spikes without exceeding 1-2 percent annual cost. Theta Time Shift provides zero-loss recovery by rolling threatened positions forward on elevated EDR or VIX above 16, then rolling back on pullbacks below VWAP to harvest additional premium. This temporal martingale has shown strong recovery characteristics in backtests. Position sizing stays conservative at no more than 10 percent of account balance per trade. All trading involves substantial risk of loss and is not suitable for all investors.
