Next weekly (Thursday) and monthly (last Thursday of the month) expiry: 27 August 2026 (Thursday). Lot size 10. Sensex retained its weekly expiry slot on BSE under SEBI&#8217;s one weekly index per exchange rule; Bankex and Sensex 50 weekly contracts were discontinued instead, in November 2024. Both weekly and monthly Sensex contracts remain available.<\/em><\/p>\n<div style=\"background: #F0F9FF; border-left: 4px solid #2E7D32; border-radius: 6px; padding: 14px 18px; margin: 18px 0;\">\n<p style=\"margin: 0; color: #1f4e79; font-size: 14px;\"><strong>Quick Answer<\/strong><\/p>\n<p style=\"margin: 8px 0 0;\">The butterfly spread Sensex is a three strike, four leg options strategy that combines a bull call spread and a bear call spread sharing a common middle strike, creating a payoff that peaks when Sensex closes exactly at the centre strike at the monthly expiry. With Sensex at Rs 77,538, the butterfly spread Sensex costs a small net debit at entry, which is the maximum loss, while the maximum profit is concentrated in a narrow zone around the centre strike. The butterfly spread Sensex may be considered when a trader has a precise view that the index will pin near a specific level by the monthly expiry.<\/p>\n<\/div>\n<p>The this strategy differs from the iron condor in an important way: rather than offering a wide profit zone between two short strikes, the butterfly spread Sensex concentrates its maximum profit in a narrow band around a single centre strike. This makes it a higher precision, generally lower cost strategy, but one that requires the index to land close to a specific level rather than simply staying within a broader range.<\/p>\n<p>Because Sensex only trades monthly contracts, the the position requires the index to be near the chosen centre strike specifically at the monthly expiry, which is a longer and less certain prediction window than a Nifty 50 weekly butterfly would require.<\/p>\n<p style=\"margin-top: 24px;\"><a

Sensex is the one BSE index that retained its weekly expiry slot after the November 2024 SEBI rule limiting each exchange to a single weekly expiry index; Bankex and Sensex 50 lost their weekly contracts instead. Sensex offers both weekly and monthly contracts, both expiring on Thursday following the September 2025 NSE and BSE expiry swap. The example in this article uses the monthly contract, but the same structure can be built on the weekly contract as well.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_is_the_current_lot_size_for_Sensex_options\"><\/span><strong>What is the current lot size for Sensex options?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Ans.<\/strong> The Sensex lot size is 10 units effective from January 2026, reduced from 15.
