last year I had derivative trading activities thus I filed ITR3 in that I treated my entire equity holdings as trading stock, but in current year I do not have any derivative and intraday trading activities thus no business income but have sale and purchase of equity shares activities all STT paid , so next AY of current year I am planning to file ITR2, there is no doubt about STCG but can I consider/claim LTCG on the sale of the stock which I had purchased two to five years back that is holding for more than 365 days) but unknowingly I included those shares in the closing stock of Last year while filing ITR3, can I treat last year closing stock as current years investment stock so that upon sale of those I can claim/consider them for LTCG
