Key points at a glance
- A conventional CFD may reference a share, index or another underlying asset.
- An options CFD adds another price layer between the underlying asset and your CFD: the price of an option.
- Time to expiry and implied volatility can change the option price even when the share barely moves.
- Contract size, margin, settlement and availability depend on the specific provider terms.
Which price moves your contract?
Share CFD
One reference: the share
Options CFD
Additional influences: time, strike and volatility
Two CFDs, two different reference prices
CFD stands for contract for difference. You agree with a provider to settle the change in a quoted price between opening and closing a position. A long position generally benefits if that CFD price rises; a short position if it falls. Long and short describe the direction of your CFD position.
For a share CFD, the difference is derived from a price linked to the share. The share is the underlying asset, but you do not become a shareholder. An index CFD similarly refers to an index without giving you ownership of its constituent shares.
For the options CFD in this article, the reference is an option price. That option price in turn depends on an underlying asset. The CFD therefore adds a second pricing layer. The exact arrangement may differ by provider, so the product name alone does not tell you enough.
Compare the contracts side by side
We compare a CFD on a share with a CFD on the price of an ordinary call or put option. Special structures may add further rules.
| Feature | Share CFD | CFD on an option price |
|---|---|---|
| Counterparty | CFD provider; over-the-counter contract | CFD provider; over-the-counter contract |
| Reference price | Share price | Price of an option on an underlying asset |
| Call or put | No call/put feature; the CFD can be long or short | A feature of the referenced option; the CFD can also be long or short |
| Strike | No option strike | Strike of the referenced option |
| Expiry | Cash share CFDs often have no fixed expiry; other CFDs may | Reference expiry and CFD settlement follow the terms |
| Barrier | No product knock-out barrier in an ordinary share CFD; margin closure remains possible | Not automatically a barrier; inspect the structure and terms |
| Leverage / margin | Collateral for the position | Option-price sensitivity plus any CFD margin arrangements |
| Financing | Cash CFDs often have ongoing financing adjustments | Do not assume the same rule; check charges and product terms |
| What you own | No share | No exchange-traded option or its exercise right |

The share rises, yet the options CFD falls
Consider a hypothetical example without fees, financing or spread. A share rises from €100 to €102. A long share CFD representing ten share equivalents gains €2 × 10 = €20. In this example, one euro of share movement changes the position value by ten euros.
Now consider a call option on that share with a €100 strike. Its assumed price falls from €5 to €4.50 during the same period, perhaps because less volatility is priced in and time has passed. This is a possible teaching scenario, not a forecast or an option-pricing calculation.
Assume an options CFD represents ten option-price units. The long CFD then changes by (€4.50 − €5) × 10 = −€5. Ten units are chosen solely for this example; they are neither an exchange multiplier nor a standard provider contract size. The example compares price mechanics, not equal capital or equal leverage.
- Share CFD: its reference rises by €2.
- Options CFD: its reference falls by €0.50.
- Before calculating: find out how much one quoted price unit is worth in your actual contract.
Why call, put, strike and expiry still matter
An ordinary call option is a right to buy at the strike; a put is a right to sell. A CFD on the option price trades the change in that price. The CFD does not transfer the option exercise right to you. A long CFD on a put is therefore different from a long CFD on the share.
Before expiry, an option price often includes time value: the part paid for possibilities that remain. Implied volatility describes the amount of future movement reflected in the price. Less time or lower implied volatility can reduce that part of the option price.
At expiry, valuation and settlement of the CFD follow its own contract terms. The valuation time, reference quote and final dealing time may differ. An options CFD does not automatically give you a claim to delivery of the underlying asset.
Margin, charges and access depend on the terms
Margin is collateral for a contract. It does not, by itself, define your maximum loss. A provider may close a position after losses or higher margin requirements. A tight spread—the gap between buy and sell quotes—does not remove price risk or other possible charges.
Availability is product-specific too. In its German product information, IG describes access to options CFDs only for professional CFD accounts. That describes one provider offer, not every provider and not a reason to change your client classification. The offer was checked on 9 October 2026.
A CFD on an underlying asset may reflect that asset more directly. A CFD on an option price also reflects strike, time and volatility. It therefore needs an extra check: exactly which option is referenced, and what are the settlement rules?
- Identify the exact reference and contract size.
- Check the call or put, strike, expiry and valuation time.
- Examine margin, possible closure and financing separately.
- Read the product and account terms for the relevant provider entity and client category.
Further detail: Understanding price sensitivity
An option price does not respond to the underlying at a constant rate. Delta approximates its change for a small move in the underlying if other inputs stay equal. Delta itself changes. A fixed CFD multiplier does not turn this into a constant share leverage factor.
Time decay is not a fixed daily fee. Financing on a CFD and a change in the time value of its option reference are separate effects. Even without a separately stated overnight charge, the referenced option may lose time value.
