If the index falls 10% before 1 p.m., how long is market-wide trading halted?
Indian exchanges use online, screen-based trading: BOLT on BSE, NEAT on NSE, TWS on MSEI. Trades can be proprietary or client trades. Other features: - Mobile trading: convenient, but limited by connectivity and small screens. - Algorithmic trading: computer programs that place orders when set conditions are met; fast, accurate and free of emotion, but a badly designed algorithm can misfire. Institutions use it to slice large orders. - High-frequency trading (HFT): a subset of algo trading with very short holding periods, huge numbers of orders often cancelled before execution (high order-to-trade ratios), few overnight positions. - Co-location: brokers place servers inside the exchange premises to cut latency (the delay between sending and receiving an order), for a fee. Execution sequence: order placed with broker → routed to exchange → displayed → matched electronically → confirmed → contract note generated.
