Based on my deep dive into KOSEI SECURITIES, my understanding is that their offering is primarily tailored toward Japanese residents, and their main business revolves around traditional securities, investment trusts, and derivatives like futures and options. While I’ve evaluated brokers across many jurisdictions, a key distinction with KOSEI SECURITIES is the total absence of details about a conventional forex trading platform such as MetaTrader 4 or MetaTrader 5—both of which are essential for using Expert Advisors (EAs) and automated trading systems. In my own trading, EAs require a platform that openly supports third-party algorithmic tools and scripting—typically MT4, MT5, or trading APIs. From the fee and service breakdowns, KOSEI SECURITIES seems to operate through proprietary or web-based systems instead, with no signals of automated trading availability, custom script integration, or external EAs. For me, this is a substantial limitation, especially since algorithmic trading plays a larger strategic role in risk control and market monitoring. For safety and regulatory considerations, I value the fact that KOSEI SECURITIES is FSA-regulated with a long history, which helps build trust for manual trading and investment. However, if your trading approach is reliant on EAs, I’d exercise caution and accept that this broker currently doesn’t appear to meet those specific automation needs. I always recommend verifying the actual available software directly with the broker, but for my purposes as an EA user, KOSEI SECURITIES isn’t a fit at this time.
