Moomoo has slight difference. They dont tell you exact cut off time. They also give you immediate liquidity.
The immediate liquidity is positive, but the negative is that MooMoo sell NAV is T-1, and not T. So lets say you sell Moomoo cash plus on Monday in the night, you will get previous Friday's NAV.
But if you sell the same fund with FSM or Endowus on Monday night, you will get Tuesday's NAV.
So Moomoo advantage is immediate liquidity but loss of money especially if you sell on Monday, you lose 3 days worth gains.
