How IOC futures work

A IOC futures contract is an agreement to buy or sell 4,875 IOC shares at a set price on a future date. You don't pay the full contract value — only a margin (the exchange's VaR + ELM), which is what gives futures their leverage. Work out the exact figure with the equity margin calculator.

Two ideas matter most: basis (futures minus spot, which converges to zero by expiry) and rollover (moving a position to the next series as expiry nears — heavy rollover with rising OI signals continued interest). Positions are marked-to-market daily, so profit and loss settle into your account each session.

Futures vs options on IOC

Futures give linear, leveraged exposure with unlimited profit and loss; options let you define risk (a buyer's loss is capped at the premium) and express views on volatility. Many traders use the IOC option chain for the OI walls and sentiment, then trade futures or options around those levels. Size any trade with the position size calculator.
