An in-depth guide

Futures: margin, ticks and expiry

Understand the contract specifications before calculating trade size. Low margin requirements do not mean a small contract and do not limit the loss.

Start with the contract specifications

A futures contract trades on an exchange under standardised specifications that include the asset, quantity and date, among other details. A similar name does not mean the same contract size. Check the full symbol, contract month, multiplier and minimum price increment. Obtain these details from the exchange’s specifications, not from memory or a screenshot of another trade. Without them, there is no reliable basis for translating a price movement into profit or loss.

Convert ticks into a monetary amount

A tick is the minimum price increment specified for a contract. Its monetary value depends on the specifications and multiplier. In an educational example that is not the specification of a particular contract, a tick of 0.25 points and a multiplier of 20 dollars per point give 5 dollars per tick for one contract. Four ticks against the position amount to 20 dollars before fees. Doubling the number of contracts also doubles the monetary impact of the same price movement.

Understand what margin covers

Futures margin is not a down payment on the purchase of the underlying asset. There are initial and maintenance margin requirements, and a broker may require more than the clearing requirement. Falling below the threshold may result in a demand for additional funds or closure of the position. A reduced intraday requirement does not guarantee the same requirement overnight; check the hours, changes around events and forced-liquidation terms in advance.

Also check exit and expiry conditions

Check the last trading date, first notice day where applicable, settlement method and the broker’s restrictions before expiry. Alongside these, calculate per-side commissions, exchange and clearing charges, and market-data costs. A calculator based on a stop price does not guarantee execution at that exact price. Before using the result, verify that the multiplier and units are correct, and remember that costs and execution conditions may also change the outcome.
