Connectivity

The IEX Production system will be available through Subscribers' existing sessions, IPs, and ports. No changes to physical or logical connectivity will be made for the Saturday test.
New Members of the Exchange who are not current IEX ATS Subscribers will have access to IEX only for symbols that are running on the Exchange. Such symbols are detailed below.

Scope

During the test, the following securities will transition to the Exchange, while all other securities not listed below will remain on the IEX ATS:

  • Test symbols: CBO, CBX, ZBZX, ZJZZT, ZTEST, ZVV, ZVZZT, ZWZZT, ZXZZT
  • Non-test securities: All symbols starting with 'Y' - 'Z', VALE.P, VG, VHC, VIAV, VIP, VLY, WIN, XOMA

For current IEX ATS Subscribers, all IEX functionality will be available on all securities, e.g. matching, routing, quoting. TOPS v1.4 will publish quotations on all symbols. TOPS v1.5 will publish quotations and trades on only the symbols that have transitioned to the Exchange for the Saturday test.

For participants who are not current IEX ATS Subscribers, all functionality of IEX will be available limited to symbols that have transitioned to the Exchange for the Saturday test.

Assistance

For any questions or issues during Saturday's test, please contact IEX Market Operations at 646.343.2300 or MarketOps@iextrading.com.

How does the Investors Exchange FIX Specification differ from the ATS FIX Specification?

Identifying Exchange Executions

For the securities that migrated to the Exchange for Saturday's test, IEX will populate two (2) new FIX tags on Execution Report and Trade Bust messages for executions from away venues and on the IEX Order Book, in accordance with the Investors Exchange FIX Specification.

  • NoContraBrokers (382) = 1
  • ContraBroker (375) = IEXG

Executions processed on the IEX ATS will not populate NoContraBrokers (382) or ContraBroker (375).

Routing Options

The following routing options will be replaced by the newly announced routing options, Router and Router Basic:

  • Route to Rest; a.k.a. SweepPost+ (18=r)
  • Route to Rest with Resweep; a.k.a. Router+ (18=s)
  • Route to Take; a.k.a. SweepPost (18=t)
  • Route to Take with Resweep; a.k.a. Router (18=u)

The following two new (2) routing options will be provided as a replacement for the four (4) options listed above. The two new routing options will use existing FIX Tag 18 (ExecInst) values in the Exchange FIX Specification. Therefore, participants may use the two new routing options without configuration changes.

  • Router (18=u) (Note that 'r' and 't' are accepted and converted to 'u')
  • Router Basic (18=s)

The following routing option will be retired for all symbols; there will be no replacement or mapping for the below option, so orders with utilizing this option will be rejected:

  • Route to Rest Away (18=v)

The following diagram illustrates how today's current routing options will be mapped to the new target routing options:

Default Behavior Port Setting

The Default MaxFloor (111) Override port setting will not be available, which means the MaxFloor (111) value will be used to define the number of shares displayed on the Exchange. If MaxFloor (111) is left blank, IEX will no longer default to "0" (zero) for limit orders, and the entire limit order quantity will be displayed. Omission of MaxFloor (111) for pegged orders will continue to express non-displayed pegged orders only.

Additionally, the port setting to convert orders with a time-in-force ("TIF") of SYS or GTX to a TIF of DAY will not be available.

What changes should participants expect in the Matching Engine?

Broker Priority will not be enforced for any securities during the test. Orders will be matched according to Price-Display-Time book priority.

Additionally, unlike displayed orders for securities on the ATS, displayed orders for securities that have migrated to the Exchange on Saturday will be subject to the "price sliding process" pursuant to IEX Rule 11.190(h). Displayed orders for securities that have migrated to the Exchange will no longer be subject to the Midpoint Price Constraint, which will now only apply to non-displayed orders on the Exchange.

An order eligible for display by the Exchange that, at the time of entry, would create a violation of Rule 610(d) of Regulation NMS by locking or crossing a Protected Quotation of an external market will be ranked and displayed by the System at one (1) MPV below the current NBO (for bids) or one (1) MPV above the current NBB (for offers) ("display-price sliding"). An order subject to display-price sliding will retain its limit price irrespective of the price at which such order is ranked and displayed. In the event the NBBO changes such that an order subject to display-price sliding would no longer lock or cross the Protected Quotation of an external market, the order will receive a new timestamp, and will be displayed at the most aggressive permissible price. Such orders may be re-priced once, or more than once, depending on changing market conditions and the order's limit price.

In the event that the market becomes locked, the System will observe the following practices for displayed orders:

  • Resting orders that are displayed at the price of the locking quotation ("locking price") as defined in IEX Rule 11.310, and were originally displayed in compliance with rules and regulations of the Exchange and the Exchange Act of 1934 will maintain their displayed price and quantity.
  • Displayable orders posting to the Order Book on the same side as an order which is locked and was originally displayed, as per the above statement, are not permitted to join the locking price. Such orders will be displayed and ranked by the System pursuant to the Exchange's display-price sliding practices described above.

In the event that the market becomes crossed, the System will observe the following practices for displayed orders:

  • Resting orders that are displayed at a price which has become crossed and were originally displayed in compliance with rules and regulations of the Exchange and the Act will maintain their displayed price and quantity.
  • Displayable buy (sell) orders being posted to the Order Book during a crossed market will be displayed and ranked by the System one (1) MPV below (above) the lowest Protected Offer (highest Protected Bid).

What changes should participants expect to the IEX Router?

IEX will offer the following two (2) new routing options for securities that have migrated to the Exchange for Saturday's test.

  • Router (18=u) (Note that 'r' and 't' are accepted and converted to 'u')
    • Router is a routing option under which an order is sent to the IEX Order Book to check for available shares and then any remainder is sent to destinations on the System routing table, which may include the IEX Order Book. If shares remain unexecuted after routing, they are posted on the Order Book or canceled, as per User instruction. Once posted on the Order Book, the unexecuted portion of such order is eligible for the re-sweep behavior. This routing strategy is most similar to the existing Route to Take with Resweep (a.k.a. Router).
  • Router Basic (18=s)
    • Router Basic is a routing option under which an order is sent to destinations on the System routing table, including the IEX Order Book. If shares remain unexecuted after routing, they are posted on the Order Book or canceled, as per User instruction. Once posted on the Order Book, the unexecuted portion of such an order is eligible for the re-sweep behavior.

Additionally, for securities that have migrated to the Exchange on Saturday, all communication between the IEX Router and the Exchange will be subject to an additional 350μs of latency, meaning orders from the IEX Router to the IEX Order Book, and quote data and fills from the IEX Order Book to the IEX Router will experience the additional 350μs of latency. No additional latency will be placed between the IEX Router and away markets.

How will IEX display orders for securities that have transitioned to the Exchange?

Existing TOPS feed (TOPS v1.4)

There will be no change to the existing TOPS feed (TOPS v1.4) during the Saturday test; TOPS v1.4 will continue to publish the aggregated best quoted bid and offer for all securities, including securities on both the IEX ATS as well as those transitioned to the Exchange (TOPS v1.4 does not and will not distinguish between IEX ATS and Exchange securities).

Exchange-only TOPS feed (TOPS v1.5)

The "Exchange-only" TOPS feed (TOPS v1.5) will publish the aggregated best quoted bid and offer (i.e., top of book) exclusively for securities that have transitioned to the Exchange during the Saturday test.

Note that TOPS v1.5 will be published on different multicast addresses than TOPS v1.4, so Data Recipients must submit the necessary Exchange Data Agreements and Forms prior to being configured.

How will IEX be identified on the SIP?

IEX will be identified in CTA (CQS/CTS feeds) and UTP (UQDF/UTDF legacy feeds; i.e., ASCII feeds) with a Market Center Originator ID of "V". See the CTA or UTP websites for technical specifications, the latest are linked below:

IEX will also be identified on the UTP binary feed with a Market Center Originator ID of "V". See the UTP website for technical specifications, the latest is linked below:

How can participants test OATS?

FINRA has assigned the Exchange a Destination Code of "XV".

After the test on Saturday, OATS will attempt to match Route and Combined Order/Route Reports submitted to OATS CT against the Exchange Order Data. Additionally, IEX will produce and submit OATS Route and Combined Order/Route Reports to OATS CT for the IEX Router. IEX recommends that participants also produce and submit OATS Route and Combined Order/Route Reports to FINRA.

How can participants test clearing and settlement?

Trades matched on IEX will be disseminated to the National Securities Clearing Corporation ("NSCC"), which will process clearing and settlement.

  • All clearing records sent to the NSCC by IEX will be submitted to NSCC PSE environment on Monday, July 11 using the Universal Trade Capture ("UTC") format.
  • Clearing files will be made available by the NSCC by end of day Monday.
  • Members and their clearing agent systems should be prepared to handle clearing for IEX in UTC format.
  • Client output will carry the Exchange's UTC Market Code of "170".
  • For more information regarding the UTC format, please refer to https://www.dtcclearning.com/learning/clearance/topics/universal-trade-capture.html.
