In addition, please note that certain exchanges may impose their own price caps or bands on orders at levels that can be more or less restrictive than those imposed by the executing broker, and which may similarly affect the speed and certainty of trades.
If you have a specific order that has been price capped and would like to request that the cap be raised on a buy order or the floor be lowered on a sell order, please contact Customer Service.
