hi,

I bought 10 share of A on 31/3/2010 for Rs.50.  I sold them on 1/4/2010 for Rs.100.   can I show like this?  This is short term trading.

2010 return - buy of 50 and sale of 0 = (LOSS of 50) and Ending balance of 50.

2011 return - Opeining balance of previous year of 50   and sale of 100 = PROFIT of only 50.

===> OR

should I close books of 2010 as 50 loss. and 

report all of 100 as profit in 2011 becase 2010 books were closed.

Thank you.

prasad,
