When you place an order, we block some extra amount (known as margin) to make up for the fees you might be charged.
However, the actual charges can be equal to or greater than this amount (margin). Exact charges are known only after the bill is posted after market hours. That is when your balance can change.
We also recommend checking if your balance has changed due to some of your orders that might have got executed.
To do this, check your transaction history.
