The Securities and Exchange Board of India (SEBI) has modified the existing Block Deal Framework to introduce specific trading windows and pricing mechanisms for large trades. The revised rules establish a morning window from 08:45 AM to 09:00 AM based on the previous day's closing price and an afternoon window from 02:05 PM to 02:20 PM based on the volume-weighted average price. These provisions apply to both T+1 and optional T+0 settlement cycles, mandate a minimum order size of INR 25 Crores, and require implementation within 60 days of issuance.
