## What it is
VisualHFT is an open-source Windows desktop application for real-time market microstructure analysis, visualizing live Level 2 order books, trades, liquidity, and built-in studies like LOB imbalance. It is an analytics and monitoring layer for traders and quants, not an order-execution system, and is extensible via a plugin system.

## Use cases
- visualize live level 2 order book depth and liquidity
- monitor order flow and detect toxic flow in real time
- analyze market microstructure and order book imbalance
- watch how my trading algorithm behaves under live market pressure
- compare liquidity across multiple venues
- capture and replay market events to diagnose fills and slippage

## When to choose
- you need real-time visualization of order books, depth, and liquidity on Windows
- you are a quant or researcher studying market microstructure and order flow
- you want to monitor strategy interaction with live market conditions rather than dig through logs
- you want an extensible analytics platform with community plugins

## When to avoid
- you need a system that places, routes, or executes orders - it is analytics only
- you need a cross-platform or web-based tool - it is Windows/WPF only
- you need L3 or GPU-accelerated features without a commercial license
- you want a simple charting tool without market-data connectors
