Opening Balance and Closing Balance for a day in TRM

Hi all,

I have a requirement to show opening balance and closing balance for the day for treasury module.  I am explaining the requirement below.

Date              Opening Balance     Purchase    Sale     Closing Balance

01.04.2014      1000                                                     1000

15.04.2014      1000                     500                           1500

20.05.2014       1500                                       200        1200

Can you please help me to get this done.

P.S - Its one amount key figure based on flow type we bifurcate to Purchase and Sale , and Opening balance and closing balance should be derived.

Regards,

Venkatesh

Thanks in advance
