“OSYSTIC delivered a solid and well-structured mobile trading solution with strong attention to functionality, usability, and integration requirements. Communication was clear throughout the project, and the team handled technical challenges professionally while responding quickly to feedback. I’m very satisfied with the final result and would be happy to work with OSYSTIC again.”
MT5 Mobile Trading Interface

The challenge
Build a mobile MT5-style experience covering market quotes, account state, open positions, history, charts and account/settings workflows while integrating an external MT5 REST service.
What OSYSTIC built
OSYSTIC delivered the mobile navigation and screen structure, account/settings workflows, responsive theme utilities and the provider-facing MT5 service abstraction using Expo and React Native.
Engineering Highlights
- Structured the application around dedicated quotes, trade, chart, history and settings/account screens rather than one monolithic interface.
- Isolated MT5 REST calls inside a service abstraction for account, order-history and symbol-related requests.
- Preserved a clear security boundary in the public case study by explicitly documenting the direct-client credential-flow limitation.
- Kept public evidence separate from real account numbers, credentials, session tokens and live account data.
Capabilities
- Mobile Application Development
- REST API Integration
- Service Abstraction Architecture
- Security Boundary Documentation
Public Evidence Boundary
This repository contains sanitized public proof only. The confidential delivery/source repository remains private. Implementation source, account credentials, tokens, real account numbers, client identity, live account data, and protected evidence are intentionally excluded.
Outcomes and validation
- Completed delivery with public evidence retained in the engineering case study.
