Helloo,
The loss occurring in the course of dealing in derivatives could not be treated as speculation loss.
-DCIT vs SSKI Investors Services (P) Ltd.
Citation 113 TTJ 511
Therefore It will be SHORT TERM CAPITAL LOSS and not BUSINESS LOSS.
but still if you want to treat it as a business loss then the return can be filed u/s 139(3) and as you have said that the transactions is done within the same day, your gross receipts will be your sales value of commodities.
I cant say anything about cash balance because there is no infomation of other transactions of your asseessee with me but you can show any lumpsum amount (i.e.between 25000-40000) as a cash balance in ITR as no accounts maintained by the asseessee but after that you must have to filed ITR-4.
