How much financial info to reveal?

[coltsrock]

Guys,

Looking to get some info about financial information to reveal in the "Affidavit of support" form. I have couple of bank accounts and 2 trading accounts. I do not wish to reveal more info than needed. I an showing bank account info about 2 accounts where my salary gets credited. However in these accounts they show activities where I am transferring money to my trading account and to other bank account that I am not showing in the form. So my question is two-fold here
1) Do I have to reveal information about all my bank/trading accounts in the form?
2) Will it be OK if I don't show information about trading and other accounts although there are activities showing in the bank statements.
P.S. There are enough funds in the the bank accounts that I am listing for financial support.

BTW I am trying to fill out the "Affidavit of support" to sponsor my parents visitor's visa

Thanks guys.
