Trade divergences

Bars bit-exact vs TV

Live numbers as of 7 August 2026. Zero trade divergences across 53,116 compared trades, and 99.62% of 14.1M compared bars land on the same double as TradingView — the rest inside a published 1e-9 relative band. Script-by-script results at wild.pynesys.io.

Why client-side execution

Trading platforms face the same architectural choice when adding strategy automation: server-side execution comes with infrastructure costs, data handling overhead, and customer data flow concerns. Client-side execution removes all three.

Compliance

Customer trading logic and execution data stay on the user's device. No additional data residency questions, no third-party processing pipeline, no shadow infrastructure to audit.

Cost

Strategy execution and backtesting run in the browser via WebAssembly. Your infrastructure scales with what you already run — not with a separate compute layer on top.

Branding

White-label embed. Your colors, your domain, your UX. End users see your platform, not ours.
