@RKSV,
This is regarding the annual updation of financial documents in Keystone for derivatives traders. Please consider increasing the file size limit to at least 5MB (currently it's only 2MB max).
I uploaded my past 6 months bank passbook scan onto Keystone BO and had to compress the PDF file a couple times to get it under 2MB without losing resolution. Minimum 5MB limit is essential since there can be a lot of passbook/statement entries over the course of 6 months which can increase file size.
