Although it is not easy to obtain a key, one can bid for the maximum subscription if there are high subscription numbers.
It all depends on the rate of oversubscription. The only thing you can do to increase your chances of getting maximum lots is to apply for last-day lots. However, this increases the risk of an underperformance IPO.
Make sure you include the correct DP ID number and Client ID details on the application/bid forms.
