Speculation profits, also known as day-to-day (Intraday) profits or losses on your positions, fluctuate based on your trading position and the prevailing market prices.
Why can't you use speculation profits on T+1 day?
When you sell or exit Intraday trades, the Exchange takes T+2 days to credit the profits to a broker and, subsequently, to your account. Using profits on T+1 could lead to a margin shortfall, resulting in penalties. To protect you from such penalties, we have decided to discontinue the use of speculation profits on T+1 day in your best interest.
In summary, what this means for you:
Starting from August 27, 2021, speculation profits can only be used to place trades from T+2 days, not on T+1 days. This change applies exclusively to Intraday Equity traders and not F&O traders.
