Dynamic Price Band
A dynamic price band is a flexible price collar, used mainly in the derivatives and high-band cash segments, that can be relaxed in steps during the day when genuine demand pushes prices to the limit.
For Indian F&O and certain liquid stocks, a fixed daily band is impractical, so exchanges apply a dynamic operating range, often around 10%, that is widened in increments after a cooling-off period if trading legitimately reaches the edge. This balances volatility control with the need for true price discovery.
The dynamic mechanism prevents both fat-finger spikes and the artificial freezing of a market that is genuinely moving on news. It works alongside fixed price bands in the cash segment and the market-wide circuit breaker at the index level to form a layered volatility-control regime.
