The Tokyo Financial Exchange (TFX) was established in April 1989 under the Financial Futures Trading Law of Japan. Following changes to the Trading and Exchange laws in Japan, TFX transformed from a “Financial Futures Exchange” into a more comprehensive “Financial Exchange” in 2007. By April 2010, TFX consisted of over 40 Interest Rates Futures members and over 20 FX Margin Trading/Clearing Members.

Time and Time Zone
Set the machine that hosts the TFX Gateway to run in (GMT+09:00) Japan Standard Time zone and time (Tokyo time). Do not enable Daylight Savings Time.
Required Connection Information
TFX will be migrating to a new API on Feb 3rd 2014. All previous versions of TT TFX Gateway will no longer be supported from this date.
All customers must upgrade to TT TFX Gateway 7.17.X by Feb 3rd 2014.
The exchange requires users to request new trading credentials to access the upgraded platform. This includes the following:
- ITC: Individual trader credentials (ITCs) are provided by the exchange and must be unique for each session listed in the hostinfo.cfg file.
- SenderCompID: provided by the exchange as an identifier for the firm and appears in the each session listed in the hostinfo.cfg file. This value may be the same in all order sessions.
- Primary and Backup IP addresses and Port Assignments: provided by the exchange as connectivity information.
Exchange API Interface
TFX Gateways connect to the exchange through the following APIs:
- Market Data: ITA Wave interface specification which uses UDP Multicast for real time prices and TCP for price recovery.
- Orders and Fills: FIX 5.0 protocol.
Unlike previous versions, TFX Gateways no longer require additional exchange-provided servers to establish a connection.
TFX has an in-house clearing function. For all transactions, the exchange functions as a clearing house, acts as a counter party, and ensures the performance of the obligations by the other party. TFX collects margins from market participants to secure the reliability of trading and undertakes the clearing of all the contracts made at the TFX market.
The exchange accepts only Limit and Market on Open (MOO) orders during the pre-open. Accepted orders are matched simultaneously at a single price at Market Open.
At the Market Open, order matching occurs in the following priority:
- Between Limit Orders
- Between Market on Open orders at the base price
- between Limit Orders and Market on Open Orders at the base price
During the trading session, TFX uses a price/time priority algorithm for order matching. With the price/time priority, the higher bid (or lower offer) takes priority. When the prices are identical, the earlier order takes priority.
TFX offers trading of the following products:
- Three-month Euroyen futures (EY)
- Six-month Euroyen LIBOR Futures (EL)
- Over-Night Call Rate futures (ON)
- Options on Three-month Euroyen futures (EYO)
- Calendar Spreads for Futures

Market Data: Pre-open prices do not impact a product’s Last Traded Price. Also, prices seen in Pre-Open will not impact the High/Low price for the trading session.
State Changes: Pre-Open only occurs prior to the Day (Morning) Session. The exchange seamlessly transitions from Pre-Open to Open state.
Order Entry: In the Open state, normal order entry and matching occurs. Any Market On Open (MOO) orders that were entered during the Pre-Open become active according to the exchange’s opening auction execution rules.
Market Data: All filled orders update Last Traded Price and Last Traded Quantity. In addition, only prices for orders executed in the Open state affect the High/Low prices for the trading day.
State Changes: The exchange enters the Open state at the start of the Morning, Afternoon, and Evenings sessions. After the transition from the Day session to the Evening session, as well as that from the Evening session to the Closed state, the exchange deletes all Good in Session (GIS) orders that were entered in the previous session. When transitioning from Afternoon to Evening sessions, all contracts remain in the Open state.
Order Entry: Traders may only cancel or reduce volume of existing orders.
Market Data: Modifications to orders in the Pre-trade state do not affect market data.
