CBOE Begins Order Price Reasonability Checks

February 21, 2013

[ by Howard Haykin ]

CBOE Trading Permit Holders ("TPHs") are advised that earlier this week - on Tuesday, 2/19/13 - the exchange began applying price reasonability checks to incoming orders.   That means: 

  • any buy order that is received with a limit price exceeding the amount specified in Regulatory Circular 12-47, or
  • any sell order that is received with a limit price lower than the amount specified in Reg Circ 12-47
  • will be routed to the firm’s designated booth order management terminal to allow a price check to be done.
  • Orders received before the product is in open state will be checked against the previous trading day’s closing price. 
  • Market Maker origin (M) and Away Market Maker origin (N) orders received pre-open are excluded from this reasonability check.

CBOE Contact:  Direct questions to CBOE Help Desk at helpdesk@cboe.com and (866) 728-2263.
