Compare the contract.
Different rights. Different cash flows. A research framework for futures, perpetuals, options, currency contracts, and rate exposures.
Different contracts. Different mechanics.
Structural comparison · Not live prices or a venue ranking
| Contract family | Time horizon | Cash-flow questions | Risk to investigate |
|---|---|---|---|
| Dated futures ↗ | Specified maturity | Margin, fees, settlement, and any roll | Losses and cash calls can exceed initial expectations. |
| Perpetuals ↗ | Usually no scheduled expiry | Funding, collateral, liquidation, and termination | No standard expiry does not mean no forced closure. |
| Options ↗ | Defined exercise and expiry terms | Premium, multiplier, exercise, and assignment | Holder and writer risk profiles differ substantially. |
| Currency forwards ↗ | Agreed future date | Exchange terms, credit, collateral, and unwind | Amount or date mismatches can leave exposure. |
| Rate-linked contracts ↗ | Contract-specific | Reference rate, sensitivity, collateral, and settlement | Equal notional does not mean equal rate risk. |

Define the comparison before comparing providers
Start with a specific research objective: understanding a short-lived exposure, studying a dated payment, or examining a portfolio risk. Then set the underlying, approximate exposure, reporting currency, and holding period. A universal ranking can conceal those differences. This website compares mechanics and questions, not live broker offers or execution quality.
Use equal exposure, not equal contract counts
One large contract and several smaller ones can represent similar notional, while an equal number of two different contracts can represent very different exposures. For options, even equal notional does not imply equal price sensitivity. Record the unit, payoff formula, and relevant assumptions. The notional and margin lesson explains the initial arithmetic.
Follow all the cash flows
Opening cash does not tell the whole story. Margin changes, option premiums, funding, rolling transactions, fees, spreads, and currency conversion may matter. A comparison should use a clearly defined holding period and identify uncertain components. A number missing from a provider’s summary is an open question, not a zero in the cost calculation.
Read the end of the contract
Identify last trading time, expiry, settlement method, and any position created by exercise. An option delivering a future needs a different operational explanation from a purely cash-settled option. A conventional perpetual can lack scheduled expiry while still having termination or liquidation provisions. Read the settlement guide before using maturity as a single comparison field.
Map the operating arrangement
Identify the entity or protocol governing the product, account eligibility, collateral custody, reference-price methodology, and dispute or incident procedures. A familiar brand does not prove that every product is offered by the same entity under the same protections. Verify the current arrangement in official documents. The source library supplies educational starting points, not endorsements.
Write one loss scenario and one access scenario
A price stress scenario explains what could happen to the exposure. An operational scenario explains what happens when normal access or transfers are unavailable. The two should not be collapsed into one optimistic closing-price assumption. Record what is known and what remains unresolved. A complete research outcome can be a decision that there is not enough information to make a sound comparison.
