Sebi plans rules to slow down high-speed trading

Sebi is planning to introduce steps to slow down high-frequency trading in the next three months, according to its chairman, U K Sinha. Sebi is considering mandating a fraction-of-a-second speed bump and alternating execution between computer and manual orders, the chairman said in an interview at his office in Mumbai. The regulator is also examining a proposal to prevent traders from cancelling an algorithmic order until it is confirmed by the bourse, to counter the practice of seeing an order show up momentarily before it's cancelled.
