About
Who Builds the Rules Behind the Automation?
Mercer House is a trading automation company based in Constanța, Romania, staffed by people who have sat on the execution side of the market.
Where Mercer House came from and what it actually does.
Mercer House was founded in 2019 in Constanța by a team that had spent the preceding decade working with institutional execution desks and retail prop-trading groups across Central and Eastern Europe. The founding observation was straightforward: most retail-grade automation tools treated risk management as a reporting function rather than an enforcement function. They would log that a limit had been breached; they would not prevent the breach. The platform we built inverts that priority. Risk rules are evaluated before any order leaves the system — a technically simple principle that required significant architectural work to implement reliably at sub-200-millisecond latency. Since 2019 we have onboarded over 140 individual traders and small trading desks operating across Romanian, EU, and international instruments. Our clients include systematic day traders, swing strategy operators, and small multi-manager setups that need aggregated desk-level risk limits across several simultaneously running strategies. The team in Constanța handles product development, broker integration maintenance, and client onboarding. We operate entirely in the teal-modern, high-contrast interface paradigm that the dashboard reflects — functional clarity over visual noise.
How the onboarding process works and where results depend on you.
A new client engagement at Mercer House follows a five-stage process. First, we conduct an intake call to document the instruments, session hours, and risk parameters the client intends to automate. Second, the strategy logic is entered into the rule editor — either by the client or with assistance during the onboarding session included in Pro and Enterprise tiers. Third, we run a backtesting validation against the agreed historical window and return a plain-language results report; the client reviews this before anything proceeds to live execution. Fourth, the system runs in paper-trading mode against the live broker feed for a minimum of five trading days. Fifth, and only after the client's explicit confirmation, live order execution is enabled. We are direct about what we cannot control: the profitability of your strategy is determined by your strategy's logic and by market conditions, neither of which Mercer House influences. We do not provide signals, calls, or advisory opinions on what to trade. Clients operating in regulated product classes remain responsible for their own compliance with Romanian FSA and EU MiFID II requirements. Our operational hours are Monday through Friday, 09:00 to 18:00 EET; support outside those hours is available to Enterprise tier clients via a monitored emergency channel.
“We evaluated four automation platforms over two months before selecting Mercer House. The deciding factor was not the feature list — it was the architecture briefing the team provided. They could explain exactly what happens to an order when a drawdown limit is hit mid-fill. No other platform gave us that level of transparency on order handling.”
