Sentinel

High-performance GPU-accelerated trading terminal built with C++20 and Qt 6.

A desktop workstation for visualizing market structure, order flow, and real-time data — powered by a custom rendering pipeline and a client/server architecture designed for speed.

Showcase

GPU Heatmap Rendering

High-density order book visualization with real-time updates and smooth interaction.

---

Stock Chart + SEC Insider Signals

Integrated equity charting with insider transaction overlays and contextual signals.

---

Screener Workflow

Fast symbol discovery and routing into the charting system.

---

Overview

Sentinel is built around a single constraint:

dense market data should remain fluid, interactive, and interpretable under load

The system combines:

• GPU-first rendering (no per-frame allocations)
• Real-time streaming data pipelines
• Desktop workstation UI (Qt + QML + Scene Graph)
• Trading and simulation infrastructure

---

Core Capabilities

Rendering & Charting

• GPU-accelerated heatmap (single-quad texture sampling)
• ~110+ FPS during pan/zoom with live axis updates
• Zero-allocation axis rendering
• Candle, hollow, and line chart modes
• Consistent viewport mapping across overlays
• High-density grid support

---

Market Tools

• Live heatmap chart
• Candle overlays aligned to heatmap mapping
• Stock chart workspace
• SEC insider signal overlays
• Watchlists with smart routing
• TradingView screener integration
• Order book / DOM ladder

---

Trading & Simulation

• Paper trading infrastructure
• TP/SL bracket handling (server-backed)
• Replay and backtesting groundwork
• Shared simulation core
• Algo integration foundation

---

Platform Architecture

• Client/server split
• Custom stream protocol
• TLS / WSS transport support
• Config-driven runtime
• Deterministic render/data flow

---

Recent Platform Expansion

The latest integration introduced a major expansion across rendering, trading, and system architecture.

Highlights:

• Unified chart rendering architecture
• Major UnifiedGridRenderer refactor
• Paper trading + simulation vertical slice
• Stock chart + SEC overlays
• Watchlist, screener, and DOM improvements
• Transport security (TLS / WSS)

TPO, Footprint, and Volume Profile are implemented at a foundational level but remain disabled in the UI until complete.
