T2T (Trade-to-Trade) Segment
Also known as: trade to trade, be series, t2t segment
The trade-to-trade segment (series BE/T) is where exchanges place stocks under surveillance — typically after excessive speculation or price manipulation signals. Every buy must be taken as delivery and every sell must come from your demat: intraday squaring-off is banned. A stock moving to T2T is a caution flag in itself, and orders there need full upfront money.
