# Trading overview: Lite and Pro modes on QuantDesk

> Introduction to QuantDesk trading on the V2 unified zero-copy portfolio, with Lite mode for quick monitoring and Pro mode for active execution workflows.

# Trading overview

QuantDesk V2 is built on a **unified zero-copy portfolio** architecture: sub-millisecond **account parsing** for bots and the UI, atomic on-chain state updates, and Redis-backed order-book cache reads where enabled. End-to-end click-to-fill latency still includes wallet signing, RPC, and network time.

QuantDesk offers two terminal modes:

* **Lite** for fast monitoring and straightforward actions
* **Pro** for deeper execution context and active workflows
