I think there are pros and cons to the new partially done allowed of the new BTS system,In fact,the problem highlighted by you  also applies to the board lot market eventhough the bid and ask quote may be one bid only.For eg,if you q to sell 5000 Hevea and some joker come and buy 100 shares from you at 4.59pm(assuming your price is the TCP price)you will still end up in the negative .
At least under the new BTS system,you need not pay prices like RM50 per share to get the one share required.
If u let someone else be the hero and put up his odd lot quote,you will be able to avoid the pitfall.

Unless and until the odd lot market becomes more liquid,(more buyers and sellers),this problem mentioned will persist.
