Column guide — EV & Greeks

DTE: Days to expiration as of when this report was generated. Highlighted in amber when ≤ 21 — the target window to close or roll positions to avoid gamma risk and assignment complications near expiry.
Loss/Risk: Current loss expressed as a percentage of maximum possible loss (i.e. the capital at risk). Only shown for losing positions — blank for positions currently at a gain. Formula: (current P&L / max loss) × 100. Highlighted in red when ≤ −25%, which is the stop-loss close-out threshold. Unlike Return (which is % of max profit), this metric uses the same denominator as the actual risk taken.
Return: Current mark-to-market return on the position as a percentage of max profit. 100% means the spread has expired worthless and you kept all the premium. Negative means the position is currently at a loss relative to entry. Highlighted in green when ≥ 50%, the take-profit close-out threshold. Colour is diverging: green for positive return, red for negative.
EV: Binary-outcome expected value: Chance × Max Profit − (1 − Chance) × Max Loss. Treats the trade as either expiring fully worthless (max profit) or reaching max loss — nothing in between. Negative EV is normal and expected for credit spreads: max loss is typically 4–10× max profit, so even an 80% winner produces a negative number. Use EV as a relative ranking across positions, not as an absolute signal. A less-negative EV means the risk/reward ratio is better for a given probability.
Θ Theta: Daily time decay in dollars. Positive means the position earns money each day that passes with everything else held constant. Credit spreads are short premium, so theta is always positive — you are the one collecting the decay. The Theta Concentration section at the top of this page shows how this is distributed across underlyings and expirations.
Vega: Dollar change in position value per 1% rise in implied volatility (IV). Negative for all credit spreads — you sold premium, so a spike in IV increases the value of what you owe and hurts you. The magnitude tells you how exposed a position is to a volatility event. The Vega Concentration section shows this aggregated across the book.
Γ Gamma: Rate of change of delta per $1 move in the underlying. Negative for credit spreads — a large move in either direction increases your directional exposure in the wrong direction (losses accelerate as the underlying moves against you). Near-expiry, at-the-money positions carry the most gamma risk.
IV: Implied volatility of the underlying at the time the position was entered. Higher IV at entry means you collected more premium relative to the width of the spread — generally a more favourable entry environment for credit strategies. Not updated in real time; it reflects the entry conditions.
Θ / |Γ|: Quality ratio: how much daily theta you earn per unit of gamma risk. Higher is better — the position is well compensated for the convexity exposure it carries. Useful for comparing two positions with similar probability profiles but different risk/reward dynamics. Positions with gamma = 0 (deep in- or out-of-the-money, no convexity) are excluded from ranking.
Θ / |V|: How much daily theta you earn per dollar lost if implied volatility rises by 1%. Higher is better — the position is well compensated for its volatility exposure. Low values identify positions that are cheapest to close into a vol spike: you are earning little time decay relative to how much a sustained IV expansion would hurt you. Complements Θ/|Γ| — gamma risk is acute and move-driven, vega risk is broader and regime-driven. A position can score well on one and poorly on the other.
