Futures in One Paragraph

A futures contract is an agreement to buy or sell an underlying (index, stock, commodity, etc.) at a future date at a price agreed today. Traders often use futures for directional exposure with margin—meaning a smaller upfront amount controls a larger notional. That amplifies both gains and losses.

Options in One Paragraph

An option gives the buyer the right (not the obligation) to buy (call) or sell (put) at a strike by/at expiry, in exchange for a premium. The seller takes on obligation in return for that premium—and can face larger risk depending on the structure.

Options prices move with the underlying, time left (theta), volatility expectations and other factors. “Directionally right” is not always enough if time or volatility works against you.

Vocabulary Worth Knowing

  • Underlying — the index/stock the contract references
  • Expiry — when the contract ends
  • Strike — the option’s agreed exercise price
  • Premium — price paid for the option
  • Margin — collateral required to hold certain positions
  • Lot size — contract multiplier / quantity unit
  • ITM / ATM / OTM — in / at / out of the money
  • Mark-to-market — daily P&L settlement on futures-style products

Risks Beginners Underestimate

  • Leverage can empty an account faster than cash equity mistakes
  • Expiry and time decay can hurt even when the thesis “feels” right
  • Selling options can look like easy premium until a large move hits
  • Gaps, liquidity and assignment/settlement mechanics matter near expiry
  • Broker, exchange and SEBI rules evolve—always read current product documents

Learn the Mechanics Before the Strategies

Master chart reading, risk sizing and process on simpler instruments first when possible. When you study F&O, use paper trading and structured review so the first expensive lessons are not paid with live capital.

Respect Leverage

Practise Decisions Before Size

Use BRBStox charting, replay and simulation tools to build process habits—especially risk and review—before increasing live exposure.
