Yes, here are the details:
SuperSoes
The NASDAQ is introducing a new version of its Small Order Execution System (SOES), called SuperSoes. SuperSoes will be the NASDAQ's primary order routing system and will provide automatic execution for:
1) National Market Securities only
2) Order size under 1,000,000 shares
3) Agency and proprietary orders
4) Odd-lots
The following rules apply to SuperSoes:
1) Orders may now be split
2) Allowed interval between trades reduced to zero seconds
3) No directed orders
The NASDAQ will gradually phase in all National Market Securities on SuperSoes during the next few months. Once a security is available on SuperSoes, IB will route all orders for that security to SuperSoes, rather than Soes or SelectNet.
Non-SuperSoes Orders
For securities not listed on SuperSoes, IB will continue to route to SelectNet or Soes based on the qualifying rules that were in effect prior to the launch of SuperSoes.
