Terrace

What Terrace does

Terrace (テラス) is a privately held Japanese company, incorporated as 株式会社テラス (Terrace Co., Ltd.) and headquartered in Tokyo, that operates one of Japan's largest marketplaces for automated system trading strategies. The platform is a two-sided marketplace connecting independent developers who create trading algorithms (Expert Advisors and strategy files) with Japanese retail investors who purchase them. Products span three asset classes: FX (MetaTrader 4-based EAs), Japanese stocks (compatible with System Trade Master and Shisutore Tamashii verification platforms), and Nikkei 225 futures. Each listed system is verified against 11 standardized performance metrics including total profit rate, average annual return, win rate, profit factor, maximum drawdown, Sharpe ratio, and expectancy, with forward-test performance tracked separately from backtest results post-listing. The platform additionally offers a portfolio comparison tool for up to three systems, user reviews, and an EA WEB Authentication anti-piracy service for MetaTrader 4 EAs.

The underlying technology is a web-based marketplace built around performance verification, product listing, and transaction processing. The platform integrates with multiple execution environments including MetaTrader 4, MetaTrader 5 (discontinued), TradeStation, Autore (server-based Nikkei 225 futures execution), and Trade Studium. Product prices range from free (promotional/reports) to ¥500,000, with most systems priced between ¥29,800 and ¥298,000. Terrace monetizes through a 29.8% commission on each sale (currently reduced to 19.8% for stock systems under a promotional campaign), a two-tier affiliate program paying 10–65% commissions to promoters, and direct sales of certain trading systems. Distribution is exclusively through openterrace.jp, the company's own website, supported by earned media coverage in major Japanese financial publications.

Terrace was founded in 2008 and operates as a small, privately held company with no disclosed external investors, funding rounds, parent company, or institutional ownership. The company's stated mission is to make Japanese individual investors' investment performance the best in the world. There is no disclosed headcount, no public revenue reporting, and no published contact information beyond a website-based inquiry form.
