General Information

NSDQ Order Routing

 

Order Types Description

Limit

Matched against existing orders on the NASDAQ Single Book or routed to other exchanges if a better price is available.

Limit Invisible

These orders are never displayed on the book or in Level II.

*Market Peg

Pegs the order price to the ask if buying or to the bid if selling, meaning the order price will automatically adjust as the bid or ask moves until the order executes or the stock trades beyond your limit price. Orders may be adjusted a penny up or down to avoid locking the market.

EXAMPLE

  • XYZ is currently quoted at 20 bid x 20.05 ask.  
  • A Market Peg order to buy XYZ with a limit of 20.10, will be submitted at 20.05.
  • If the quote changes to 20.05 bid x 20.10 ask, the order price would change to 20.10.
  • If the order is not executed, it will not update beyond the limit price and will remain posted at 20.10.

*Primary Peg

Pegs the order price to the bid if buying or the ask if selling OTC securities, or the best exchange bid/ask for Listed securities. The order price will automatically adjust as the bid or ask moves until the order executes or the stock is priced beyond your limit price.

EXAMPLE

  • XYZ is currently quoting at 20 bid x 20.05 ask.  
  • A Primary Peg order to buy XYZ with a limit of 20.05, will be submitted at 20.
  • If the quote changes to 20.05 bid x 20.10 ask, the order price would change to 20.05.
  • If the order is not executed, it will not update beyond the limit price and will remain posted at 20.05.

 

Times in Force Description

Day

Can be entered after 7:00 AM ET and expire at the end of the extended trading day (8:00 p.m. ET)

IOC

Portions of the order not filled immediately upon reaching the market are canceled.

 

Special Conditions Description

*Min Qty

A special condition that specifies the minimum execution quantity the client will accept (with any amount up to the specified Quantity thereafter). Available for limit IOC orders only.

*Max Floor

Specifies the reserve size for the order. Must be a round lot equal to or less than the order quantity. Reserve size has no time priority in Level II. Only the displayed portion of the order will have time priority.

EXAMPLE  You enter a bid with 5,000 as the total quantity, but 1,000 as the Max Floor value. Your order will display as 1,000 shares, but if yours is the only bid when an offer arrives for 10,000 shares at your price, your entire 5,000 shares will execute.

However, if 3 other bids for 3,000 shares each were behind you at the same price, only your displayed 1,000 would execute, along with 9,000 shares from the other three bids.

*Peg Diff

Added to the bid or offer to produce the actual order price. Allows more flexibility in your order.  

EXAMPLE  To peg the offer minus .02, Peg Diff must equal -0.02 (the negative sign is required).

 

* Features only available when Spec Cond & Brackets is checked in the Trading window.
