Exchange Information

Exchange Background

The Osaka Securities Exchange is the leading Derivatives Exchange in Japan. The Exchange was originally established in 1878 as Osaka Stock Exchange Co., Ltd; by 1949, Osaka Securities Exchange was established.

The Nikkei 225 Futures and Options, based on Japan’s leading stock index, the Nikkei 225, are OSE’s flagship products. OSE launched the Nikkei 225 mini in July 2006, creating investment opportunities for retail investors.

OSE continues to improve its services for both local and overseas traders. In February of 2011, OSE introduced a new derivatives trading platform, J-GATE, which reduced processing speed and simplified trading. In 2016, OSE introduced the Next Generation Derivatives Trading System (Next J-GATE) platform, which includes a new ITCH price feed in addition to OM API changes.

Note

TT connects only to the OSE Derivative platform (J-GATE). OSE Cash products are not be available to trade through the TT OSE Gateway.

Required Connection Information

Users must work with the Exchange to acquire the following connection information:

  • User IDs

Exchange API Interface

OSE uses the Next Generation Derivatives Trading System (Next J-GATE) ITCH price feed for real-time prices, and the OM API interface for connectivity. For a list of required broadcasts, refer to the section called Exchange API Text Fields.

Matching

The OSE matching engine is located in Tokyo.

Prices at OSE are determined through Price/Time Priority, called Zaraba. To accomodate transactions conducted at closing price, OSE has introduced a Closing Auction system, referred to as Itayose, which is also present during Pre-Open and determines the opening price. In the Closing Auction system, matching is made at the same time as the closing of the order acceptance period.

Note

Previously, OSE implemented Douji-Yobine, a simultaneous bid/offer rule. This rule no longer applies in the Next Generation Derivatives Trading System, J-GATE. All prices are determined via Price/Time Priority.
