Game portfolio shows the shares that you are holding currently.
Here is an interpretation of how to see it.
What's the difference between the cash at hand and game limit?
I will use a simple example,
you have RM100,000,
and you place order of 60,000.
If the trade isn't completed yet,
then, you will still have RM100,000 in hand.
But, you have only RM40,000 limits for trading.
