About ZEROHUE
Practice crypto trading with live market context and no signup required.
What is ZEROHUE?
ZEROHUE is a crypto trading simulator built for deliberate practice. It pairs live market context with simulated execution so traders can rehearse entries, exits, and risk decisions without funding an exchange account.
It is local-first by design. Prices come from Binance and Coinbase, execution stays simulated, and your practice record stays on the device without signup.
- Live market context from Binance and Coinbase
- Simulated execution with order and risk controls
- Local-first storage in browser storage and IndexedDB
How local-first storage actually works
ZEROHUE keeps lightweight app state in browser storage and structured trading records in IndexedDB. The goal is simple: restore the practice session locally without needing an online profile.
Browser storage for lightweight state
Preferences and small pieces of app state stay in browser storage so the app can recover quickly after a refresh.
IndexedDB for trading records
Orders, transactions, and market-history snapshots are stored in IndexedDB so the main practice record stays in the browser.
Privacy, with a tradeoff
Less data needs to leave the device by default. The tradeoff is that moving between devices is less seamless than in a cloud-synced product.
Traditional online simulators vs ZEROHUE
The main difference is where the practice record lives and whether practice starts with signup.
Signup model
Traditional online simulators often need signup and an online profile so the service can save sessions, watchlists, and practice history.
ZEROHUE works without signup. Simulator state lives in the browser, making it easier to start and reducing default data collection.
Where records live
Orders, journals, and settings are usually stored in a hosted database so they can be restored across devices.
Orders, transactions, and replay history stay in browser storage and IndexedDB on the device unless you move that data yourself.
Main tradeoff
Remote sync makes cross-device access and recovery easier because the server keeps the main copy.
Local-first design favors privacy and control. The tradeoff is that moving between devices is less seamless.
