Negetive balance

Hi fellow members,
What happens if my cash balance is showing -ve. Am i still allowed to carry the trades ?
I took some postions and converted to nrml. it showed negetive balance but did allow me to do so.
Any problem ?

You are charged interest at some ginormous annual rate for every single day that your balance remains negative. If you are OK with paying this interest, I believe there is no problem for having a negative balance.
