Debit Spread Analyzer

How to Analyze Debit Spreads Before Entry

Debit spreads—whether call or put—require precise alignment between price movement, timing, and strike selection. Unlike naked options where you simply need the stock to move, spreads have a defined profit zone that must be reached before expiration for maximum gain.

Many traders misjudge breakeven feasibility. A call debit spread might cost $2.00 with $5 width, but if the stock needs to move 8% to breakeven and the expected move is only 5%, the trade is statistically unfavorable despite the "limited risk" structure. This analyzer quantifies whether your spread has real edge.

Why Expected Value Matters for Debit Spreads

Maximum profit potential is a misleading metric. A spread with $300 max profit sounds attractive, but if there's only a 15% probability of reaching it, your expected value may be negative. EV incorporates both the probability of each outcome and its payout, giving you the true mathematical edge.

A spread can look "safe" because of its defined risk structure yet still have weak or negative edge. The cost you pay reflects market expectations—if you're paying $2.50 for a spread that's statistically worth $2.00, you're buying at a premium with negative EV.

This tool separates what you hope will happen from what the probabilities actually suggest, using real implied volatility and price data to model outcomes.

How the OptionEV Technical EV Analyzer Works

This analyzer combines two powerful approaches:

• EV modeling across price paths: Simulates where the stock might be at expiration using implied volatility, then calculates expected payoff across the probability distribution.
• Expected move vs required move: Compares what the stock is statistically likely to do against what it needs to do for your spread to profit.
• Breakeven feasibility: Shows whether your breakeven price is within the expected move range or requires an unlikely move.
• Technical indicator integration: Blends EV analysis with RSI, trend direction, and support/resistance levels to identify confluence or divergence between technicals and probabilities.
