Nexgent Trading Engine

Nexgent is an open-source, self-hosted trading automation framework for Solana. Deploy your own instance, create trading agents, and execute trades with ultra-low latency.

Trading dashboard showing performance metrics, live positions, and balance history

Why Nexgent?

Feature	Description
Self-Hosted	You deploy and control your own instance. Your data, your keys, your infrastructure.
Open Source	Full source code access. Audit, modify, or extend any feature.
No Fees	Zero per-transaction fees. Only pay Solana network costs.
Ultra-Fast	Sub-500ms signal processing, sub-1ms stop loss evaluation.

How It Works

Signal → Agent Eligibility → Trade Execution → Position Monitoring

Signal Creation – Trading signals arrive via API
Agent Evaluation – Each agent checks eligibility (balance, config, filters)
Trade Execution – Eligible agents execute via Jupiter Aggregator
Position Management – Real-time monitoring with stop loss, DCA, and auto-close

All state changes broadcast via WebSocket for live dashboard updates.
