Calculate delta in shares before choosing a hedge
Delta hedging offsets the local sensitivity of a position to its underlying price. For equity options quoted per share, portfolio delta in equivalent shares is signed stock shares + Σ(signed contracts × contract multiplier × option delta). A short position has a negative quantity. Keep the quoted long-option delta positive for calls and negative for puts.
A long put with delta -0.40 and multiplier 100 contributes -40 shares per contract. Selling that put reverses the exposure to +40 shares. Read the multiplier from the contract specification; a deliverable altered by a corporate action may not fit a simple shares-only calculation. Cash-settled index options and mixed-underlying portfolios need a different hedge model.
A reproducible delta-neutral strategy example
Use hypothetical XYZ at $100, with +100 stock shares and -2 call contracts. Each call has delta 0.60, gamma 0.03 per $1 and multiplier 100. Current delta is 100 + (-2 × 100 × 0.60) = -20 shares. Enter a target range of -5 to +5 shares. Buying 15 shares reaches -5; buying 20 reaches zero but trades five more shares.
| Step | Calculation | Exposure or cost |
|---|---|---|
| Initial range hedge | -20 + 15 | -5 shares |
| Stock rises $2 | Call delta ≈ 0.60 + 0.03 × 2 | 0.66 per share |
| Hedge held unchanged | 115 - 2 × 100 × 0.66 | -17 shares |
| Rebalance to range | -17 + 12 | -5 shares |
| Rebalancing cost | 12 × $0.02 + $1 ticket fee | $1.24 |
| Rebalancing notional | 12 × $102 | $1,224 cash exchanged |
The initial 15-share trade costs $1.30 under the same assumptions; total modeled transaction costs are $2.54. These are invented inputs for arithmetic, not a market quote or observed trading result. The example measures exposure and costs, not the profit from gamma scalping.
Transfer TradingView contract inputs without changing their meaning
- Open the TradingView options chain for the underlying. Record call or put, strike, expiration, delta and gamma, and check the quote time. TradingView describes these Greeks as theoretical sensitivities.
- Confirm whether a displayed Greek is for one option unit or an entire position. This form expects per-share long-option Greeks; enter contract quantity and multiplier separately. Do not multiply a position Greek again.
- Match the actual contract deliverable and stock symbol. Use manual inputs when the exact contract snapshot is missing; the calculator does not substitute a nearby strike or expiration.
- Choose a target measured in shares and inspect each signed position contribution. After a price move, compare a fresh delta with the local gamma estimate and review the additional shares and costs.
TradingView strategy charts can display combined Greeks and scenario curves. Their displayed totals can be useful cross-checks only after quantity, multiplier, reference price and units agree. This page does not connect to TradingView or import its positions.
Where the hedge calculation stops being useful
Zero delta removes only the first-order price sensitivity at a point. Gamma, volatility, time decay, dividends, exercise, assignment and gaps remain. A fixed-gamma estimate can become inaccurate before it violates the mathematical delta bounds, especially near expiration or after a large move. Refresh the actual Greeks before treating the result as a tradable quantity.
A tighter band may require more trades; a wider band leaves more residual exposure. Whole-share rounding can make a narrow band impossible to reach, which the calculator reports. No default band is suitable for every account. Short selling may require permission, margin and stock borrow; estimated transaction costs here exclude those obligations.
The historical-price chart applies today's positions and Greeks to past stock prices. It is a sensitivity illustration, not historical option Greeks, executed hedges or strategy performance. Invalid linear estimates are omitted. Only the first returned page of up to 250 contracts is inspected; a missing match may exist beyond that page. Data can be delayed, incomplete or unavailable, and manual inputs remain the user's responsibility.
