The definition above is the short version. A full explanation — how it works, a worked example and the exam traps — is still being written. In the meantime the chapter below covers it in context.

Written up from the same chapter

• Algorithmic tradingAny order generated by automated execution logic rather than typed in by a person — software that pushes buy and sell orders into the exchange once its parameters are met.
• Authorised personTwo different entities share this name: under SEBI, an agent appointed by a stock broker to give clients access to the trading platform; under FEMA, a dealer authorised by RBI to deal in foreign exchange.
• Base priceThe reference price a contract starts each trading day from — the theoretical futures price on the day it is introduced, and the previous day's daily settlement price on every day after.
• Clearing corporationThe entity that steps between every buyer and seller in the derivatives segment by novation, becoming the counterparty to both sides and guaranteeing that the trade settles.
• Commodity Transaction TaxA transaction tax on non-agricultural commodity derivatives — 0.01% on the sale of a futures contract, paid by the seller, with separate rates for options.
• Compulsory deliveryA delivery logic under which every position still open at expiry must give or take physical delivery — neither side can elect to settle in cash.
