Short-selling is strictly not allowed.
For intra-day trading, client is able to Sell as soon as the Buy trade is confirmed.

Also please note:

Limited exchange hours & follows SG holiday (vs other exchange which runs 24hrs) – i.e. Client is unable to sell position with us when the exchange is closed à For e.g. even if the price come off a lot during US hours, your client can only place order to sell in the next morning 8.30am Singapore time (actual matching will only start from 9am).

Counterparty risk – Should the counterparty fail to deliver the coins, the exchange may do the opposite trade on the next day to unwind the trade, and any p&l will be borne by your client à For e.g. Client buys 10 Bitcoin at 23k on T, counterparty fails to deliver the coin and on T+1, the exchange will sell off the 10 Bitcoins on behalf of the client at market. Assuming the market price on T+1 is 15k, client will realised a loss of 80k (23k-15k per coin).
