Dear Sir or Madam,

I heard you were requesting public comments on proposed rule NSCC-2021-801 until April 9 and I wish my voice is still going to be heard and taken care of.

I extremely agree with the new transparency approaches of this rule and think it would have to be applied as soon as possible (to have public control about dark-pool trades, naked shorting, Fails To Deliver and other usual practices which, thanks to their abuse, members of the DTCC so widely use to manipulate the price of stocks).

I also agree and look forward for the NSCC assessing the risk of members in a daily basis, it's possibility to demand higher SLD daily, and for the DTCC having allowance to liquidate member's possitions if they jeopardize the NSCC's ability to complete the day's trades.

Thanks a lot, I wish this necessary rule is applied as soon as possible.
