Short answer

iRage sets the retail allotment price as the default average price for shares allotted in an IPO to your iRage demat account. If the allotment price is not the same, you can create a ticket for the iRage team to manually update your holding price.

If you transfer shares to your iRage demat account after allotment in a different demat account, you need to update the acquisition/allotment price in Console.
