Self-custodial desktop trading terminal
TickWright
A purpose-built Electron terminal for short-interval prediction markets, combining live market context, order books, bracket execution and safety controls in one fast desktop workflow.

The constraint
Short market windows make browser tab switching, delayed feeds and manual exits costly. At the same time, a faster workflow could not come at the expense of key custody or execution correctness.
What I built
I connected four concurrent Binance and Polymarket feeds, kept signing and credentials inside the desktop main process and built exactly-once fill accounting for unordered events. Bracket exits, maker-only orders and kill switches are handled as product features, not afterthoughts.
