Can I buy stocks using Pay Later (MTF) on a settlement holiday?

Yes, stocks can be bought or sold using Pay Later (MTF) on a settlement holiday. However, T1 holdings (i.e., BTST holdings) cannot be sold on a settlement holiday. For example, if Friday is a settlement holiday and you bought stocks on Thursday using MTF, you won't be able to sell them on Friday.
