UI/UX Design

Experts in financial technology design, turning the complexity of trading, brokerage, and wealth interfaces into clarity, familiarity, and usability traders appreciate.

Modulus designs goal-driven financial interfaces. Drawing on technology used by millions of traders, our design teams know exactly what financial users want before they ask.

As a modern, AI-accelerated fintech company with 30 years of capital-markets experience and millions of lines of production-proven source code, Modulus delivers designs created by senior designers and accelerated by AI.

A Modulus trading platform interface designed for clarity and data density

Design that fits what traders want

An engagement with Modulus starts with your goals, not a template or a script. Whether you are launching a new product, modernizing an outdated user interface, or attempting to decipher why users struggle using your app, we shape the work to your unique needs.

Most traders have strong preferences about trading app designs and layouts. They expect apps to feel familiar and intuitive. A trading workflow has to surface prices, positions, orders, and risk at a glance, so we maximize information per pixel while keeping the layout scannable, with clear hierarchy, restrained color, and real-time updates that inform without stealing focus or shifting the layout under a click.

We design for how trades actually happen: configurable workspaces, layouts, and macros, order-entry flows with confirmations and fat-finger protection, unambiguous order and position states, and charting interactions across timeframes, indicators, and drawing tools that respond instantly. Color carries meaning for gains and losses while staying legible for color-blind users.

Interfaces for every type of application

Financial products are ecosystems, and we design across the whole of yours. From the trader-facing terminal to the back-office tools your staff rely on, we bring a consistent, branded experience to each surface.

We turn complexity into clarity wherever it lives, across trading platforms and terminals, broker CRM systems, financial charting libraries, client and administrative portals, wealth and portfolio management platforms, and the multi-asset account and AI assistant interfaces increasingly woven through it all.

Grounded in usability and accessibility

Our UI/UX designs are based on real-world consumer usage information and proven user-empathy frameworks, not aesthetic guesswork. We design and evaluate every interface against established UI/UX principles and observed user behavior.

In practice that means structured usability testing, heuristic evaluation against established principles, and information architecture that matches how financial users actually think, so the path to a quote, an order, or a report is short and obvious. We watch where users hesitate and remove the friction rather than documenting it.

Accessibility is a baseline, not an afterthought: we follow W3 standards so your product performs cleanly for every user, across every device.

On accessibility, that comes down to concrete details: sufficient color contrast, full keyboard operability, screen-reader support, and color choices that stay meaningful for color-blind users, so gains and losses never rely on red and green alone.
