I know there are some counters in Bursa Malaysia able to do Short Selling. However, I am not so familiar with this. I have some question on this.

1. Are there any periods for me to buy back the share that I already short sell?
2. Is the transaction charges same as normal buy and sell charges?
3. Are there any additional interest apply during the period before I buy back the share?
4. Is the short selling transaction can be done via e-trading?
5. What is the different between Regulated Short Selling (RSS) and Security Borrowing and Lending (SBL)?
