JPX Overview

TT supports trading on JPX (Japan Exchange Group), which is the leading Derivatives Exchange in Japan. JPX is the company created by the merger of TSE (Tokyo Stock Exchange) and OSE (Osaka Securities Exchange).

In 2016, JPX introduced the Next Generation Derivatives Trading System (Next J-GATE) platform, which includes a new ITCH price feed in addition to OM API changes. In 2021, trading on OSE and TOCOM via TT is supported by connecting to the JPX J-GATE 3.0 interface. This mandatory API upgrade merges the existing OSE and TOCOM markets into a single "JPX" connectivity and trading/matching solution using the same platform already in use by those markets.

JPX Exchange API

TT® supports the following:

  • Prices: ITCH / OM Combo
  • Orders: OMAPI

Matching Engine

The JPX matching engine is located in Tokyo.

Matching Algorithms

Prices at JPX are determined through Price/Time Priority, called Zaraba. To accomodate transactions conducted at closing price, JPX 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.

Supported JPX products on TT

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