Pledging of Shares

What is CSMFA and why are my shares auto pledged in MTF in CSMFA?

It is an account the broker maintains with the depositories to manage pledges of securities bought through the Margin Trading Facility (MTF). When you purchase shares under MTF, they are automatically pledged in favour of ICICI Direct – CSMFA in your demat account. If the pledge cannot be created, any unconfirmed MTF position will be squared off (closed) within five working days of the payout date.
