What is Perpetual Futures?

Perpetual futures simulate spot exposure without expiry through funding rate mechanism.

Formula

Funding Rate = Clamp(Premium Index, -0.05%, 0.05%) + Interest Rate

Indian market context (NSE)

Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Perpetual Futures shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Nifty at 24,300: weekly/monthly option chains centre on round strikes (24,000 / 24,500). Perpetual Futures on ATM Nifty options shifts quickly into expiry — India VIX and event risk (RBI, budget) reprice premiums independent of spot.

Bank Nifty futures perspective

Bank Nifty futures at 55,000: hedging with options or trading perpetual futures on Bank Nifty weekly contracts — theta and gamma rise sharply into Thursday expiry; futures leg has no time decay but carries overnight gap risk.

How to validate

  • Validate Perpetual Futures separately for index weeklies vs stock options.
  • Stress-test with expiry-week and event-week subsets (RBI, budget, results).
  • Confirm margin and tail-loss scenarios are logged for short premium books.
  • Discard readings polluted by untagged discretionary adjustments.

How to track in TradeLyser

  • Tag every leg: structure, DTE, moneyness, and whether Perpetual Futures was a primary driver.
  • Log planned max loss ₹ on entry for short premium strategies.
  • Weekly: list open short ITM/ATM legs before expiry with a written roll/close rule.
  • Separate F&O account tags from cash equity for Perpetual Futures statistics.

Best practices

  • Size Perpetual Futures trades with margin headroom for gaps and assignment.
  • Prefer defined-risk structures when learning a new options concept.
  • Roll or close based on written DTE rules, not convenience.
  • Keep weekly index and monthly stock books in separate tags.

Common pitfalls

  • Short premium without defined max loss while Perpetual Futures risk builds.
  • Holding illiquid stock options into expiry without a plan.
  • Blending index and stock gamma exposure in one tag.
  • Ignoring margin spikes on gap opens.
