I understand a buy limit because they are not sure if you have enough fund to buy. But why they limit you to sell the stock that you already have? Why can't I sell all my stock all at once if i choose to?
It's because CDP is dopey.
The brokers can't see into CDP, so they don't know how much you hold of any particular share - and if they don't know how much you own, they don't know how much you can safely sell. Without a limit in place, you could sell eleventy-three zillion shares of DBS or whatever and they wouldn't be able to prove that you didn't own them.
That said - if you're panicking and selling all your shares because the market has gone down, STOP.
The market goes down sometimes. Sometimes it goes down slowly; sometimes it goes down quickly. But you shouldn't care. If you're investing in the market, it should be with money you need for the long term: money that you don't need for five or ten or more years. And if that's what you're doing, then this is just a blip - in five years' time we'll look back and say "oh that thing? man that was rough, but look how far we've come".
Since the Flash Crash in 2010, the SPX has gained about 60%. In the five years after the 1987 crash, the market gained about 60% as well.
Down here, you can buy the same great stocks 10% cheaper than a week ago. Is DBS 10% less valuable than it was a week ago? What about the Jardines? What about Apple? (OK, maybe I'll give you Apple, given that they reported such weak earnings out of China.) What about JP Morgan, or Kroger supermarkets (which briefly traded down 25% this morning)?
