What is Contango?
Contango describes a forward curve where later futures prices are higher than nearer ones — or futures trade above expected spot fair value. Rolling long positions in contango often means buying higher and selling lower across tenors, creating negative roll yield.
What contango is
Contango is a curve shape, not a trade signal. Commodity markets made it famous, but index futures show similar patterns when financing costs dominate. Negative roll yield erodes long-only futures carry strategies.
Indian market context
Nifty term structure varies with RBI rate path, dividend season, and risk sentiment. Before monthly roll, compare near vs next prices on NSE — steep contango favors timely roll timing or spread awareness.
Multi-week long futures strategies on Nifty should budget contango drag as a recurring cost line — similar to brokerage. If your directional edge is +120 points per month but roll costs −90 points, the journal should show net +30, not headline +120.
Steep contango sometimes coincides with bullish sentiment; do not confuse curve shape with edge. Tag calendar rolls separately from directional entries so TradeLyser expectancy math stays honest.
Worked example
| Contract | Price |
|---|---|
| Near month | 24,260 |
| Next month | 24,340 |
| Spread | +80 pts contango |
| Long roll cost | ≈80 pts if rolling long (simplified) |
Common mistakes
- Ignoring roll when reporting futures strategy returns.
- Confusing contango with bullish trend.
- Rolling on illiquid wide-spread minutes.
- No tag for calendar/roll trades in analytics.
How to validate
- Validate Contango 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 Contango 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 Contango statistics.
Best practices
- Size Contango 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 Contango 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.

Related terms
Backwardation is the opposite curve shape to contango: nearer futures trade below further ones, or futures trade below fair spot. Long positions rolling in backwardation may capture positive roll yield — common in some stress or tight supply narratives (more typical in commodities than indices).
Basis is the difference between the futures price and the spot (or fair) price of the same underlying — typically futures minus spot. Positive basis (futures above spot) is common in index futures when financing and dividend expectations embed in pricing.
A futures contract obligates parties to transact the underlying at settlement per NSE rules, with daily mark-to-market and margin.
Index futures are standardized NSE F&O contracts on benchmark indices (notably Nifty 50 and Nifty Bank) that cash-settle against official closing prices. They offer leveraged exposure to broad market direction with transparent lot sizes and deep liquidity relative to most stock futures.
Mark to market (MTM) is the daily revaluation of open derivatives positions against the exchange settlement or closing price, with profits credited and losses debited to your ledger. On NSE F&O, MTM runs on open futures and options positions so capital reflects current risk, not just entry price.
Rollover closes or shifts positions from near-expiry contracts to the next series, avoiding delivery or illiquid last days.
FAQ
Is contango bad for long futures?
It imposes roll cost when you extend holding across tenors. Direction can still profit if move exceeds roll drag — log both components.
Do Nifty weeklies show contango?
Weekly vs monthly structure differs — compare relevant tenors on the same underlying for your hold period.
