What are Trade to Trade or T2T stocks?

Exchanges move highly speculative stocks or those suspected of price manipulation to the Trade to Trade (T2T) segment. Intraday is not allowed in the T2T segment, as all buy and sell transactions will be compulsorily delivered.

• If a trade-to-trade (T2T) stock is bought, and the client tries to sell the stocks on the same day, the order will be rejected. However, it can be sold on the next trading day, i.e. T+1 day. The credit from selling T1 holdings (Buy Today Sell Tomorrow [BTST] trades) cannot be used on the same day as per regulations (PDF). To learn more, see Why is the credit from selling T1 holdings unavailable for use on the same day? and What are the risks involved in BTST?
