I think this system still have bugs based on my recent experience..
There is a stock where I Q 2 times but cancelled on Friday. I made sure that there was no Q on Monday. Alas.. suddenly that Stock of 10Lots appeared on my screen as filled.. I called CS but they say doesn't appear on their screen. Strange thing is that I cannot sell
They asked me to take a screen shot and I sent to them and CC the name of the CS, so that they can followup.
Whole day no news.. the next day, I can transfer out the funds and the stock disappeared.. a few days later.. wanted to buy stocks and TT to the securities account and ALAS, the stock suddenly appeared and appeared as Filled at the buy price on Monday !!! But now I can sell.. and
the price is higher then my buy price so I happily sell.
Since I made a profit, no point complaining so let it rest.
