From my experience evaluating institutional brokers, JaneStreet stands out as a very specialized liquidity provider rather than a conventional forex broker. The platform uses a proprietary, in-house trading system developed in OCaml, which immediately signals that mainstream retail functions like MT4/MT5 compatibility and, as a result, support for Expert Advisors (EAs), are absent. I learned that JaneStreet doesn’t cater to individual or retail traders; their infrastructure is uniquely designed for highly technical, institutional trading desks and quantitative teams who build and operate their own custom trading models directly in the platform’s native environment. This means that unless you or your team are deeply integrated into their ecosystem and able to develop within their proprietary system, you won’t have access to “plug-and-play” automated trading using EAs as understood in the MT4/MT5 landscape. In practical terms, for someone like me, who occasionally relies on established EAs for automated strategies, JaneStreet isn’t a suitable or accessible venue. Even though their quantitative research and tech capacity are impressive, the lack of public algorithmic trading support—and the high institutional threshold—makes this platform, in my view, out of reach for anyone who isn’t operating on the institutional or quant developer level. My strong advice is to consider this limitation seriously if EA usage is central to your trading approach.
