Why PI does not work in the first 8 minutes of Market Open?

I have been experiencing this problem daily with PI. In the first 8 to 10 mins of market open, when I look to put an order, the order just sits in the order window as ‘validating order.’ Then after a minute or so, that status changes to ‘order pending.’ Still the order is not placed. Then it finally after god knows when will place the order in the system as ‘open order.’

What is happening with this platform ‘PI’. There is nothing to do with too many orders in the system. The problem is with PI.

Can I get a solution for this Question?
