Re: SR-NSCC-2021-801

I support the implementation of the proposed amendment to the Supplemental Liquidity Deposit Requirements. I believe these amendments will reduce volatility associated with the rapid closing of overleveraged positions, which is important for investor confidence. I believe it also will increase market transparency and equity.
