Do the stocks move out? If so, it’ll close long term positions and be taxed. If not, it’ll be a intraday speculative business income?
With interoperability enabled, your buy and sell will be treated as intraday, while the stocks will remain in your demat, and the resulting profit or loss will be classified as speculative business income.For T2T category stocks, sell and buy will not be netted off since intraday is not allowed. Any buy order will always be treated as a fresh delivery trade.
