Duplicato: a complete trading engine for traders and their following

From stock orders to derivatives like futures and options. We built the engine, the portal, the mobile app and the trader dashboard.

Duplicato lets a trader fire off orders that are automatically followed by their following. This isn't just about stocks, but also more complex derivatives like futures and options, each with their own risks, margins and timing. Reemo built the entire system: the trading engine that processes and mirrors orders at high speed, the client-facing portal, a mobile app and the dashboard the trader uses to manage positions and followers.

The trading engine as the beating heart

The engine is the heart of Duplicato: the trader's orders are processed in real time and mirrored to their followers' portfolios. We built it to handle speed, reliability and correct processing of derivatives, even when the market gets busy.

Duplicato: one order from the trader, automatically followed by their following

Portal, app and dashboard in one experience

Followers use a client-facing portal and a mobile app to track their positions; the trader runs everything from a dashboard with real-time insight into orders, followers and results. Everything draws from the same source, so no one is left behind.
