Pre-Trade Risk Controls
Pre-trade risk controls are automated checks applied to orders before they reach the exchange, such as price bands, quantity limits and exposure checks, to prevent erroneous or excessive trades.
For Indian DMA and algo flow, brokers must run pre-trade filters that reject orders breaching price collars, maximum order size, available margin or position limits. These checks are mandated so that an algorithm or fat-finger error cannot send a wildly mispriced or oversized order to the market.
The exchange layers its own controls on top, including dynamic price bands and per-order value limits. Together with the kill switch, pre-trade risk controls form the safety net that lets regulators permit fast automated trading while limiting the chance of a systemic accident.
