Will there be any changes to existing margin and Risk Management System (RMS) requirements?

Your standard margin rules and broker safety checks stay the same. Here is a simple breakdown of how it works during the Closing Auction Session (CAS):

• Placing new orders: If you place a fresh order during the auction, you need the standard funds or margin in your account, just like during regular market hours.
• Pending orders from earlier: If you have an unfilled order left over from the regular market session, it moves into CAS automatically without requiring extra funds.
• Modifying pending orders: If you edit or change a pending order during CAS, a fresh margin check will trigger, so you will need sufficient account balance.
