I read the American derivative futures in cfa, it’s easy, since your u don’t pay any money while entering into contract, no need to record anything. But for margins, I invented this technique, capitalise margins

Margin balance Asset a/c 1000

To bank a/c 1000

and during the long position, don’t do anything about losses and gains related to basis risk and similarly margin  additional balance or loss. When you settle the contract, if you gain 1500, delivery of cash, then 

Bank 1500

To Margin balance asset a/c 1000

To gain 500

how does this sound? 

By the way, its a narrative principle your asking. there are positions with hedge and without hedging, And there are different hedging techniques which are available in your books. As per the tax part, 

A. Delivery based- it falls under Capital gains or PGBP

B. Inraday based- it falls under PGBP

C. Trading- Presumptive scheme of taxation and income tax slab rates applicable to income from business.
