Auditability first
Every decision the engine makes is recorded as an immutable operation record — timestamped, explained and replayable. No black boxes.
About us
Wall Street Cloud (wall-street.cloud) started as an internal institutional sandbox for verifying Bybit token-stock trading decisions in real time. The tooling was too useful to keep private — so it became a platform: a bot engine that shows its reasoning, a scouter that ranks entries before they are obvious, and a backtesting lab that uses the exact same decision code as production.
Today the platform runs continuous decision cycles across hundreds of assets, records every fill and rationale in an immutable operations ledger, and gives traders a keyboard-driven terminal to supervise all of it.
Principles
Every decision the engine makes is recorded as an immutable operation record — timestamped, explained and replayable. No black boxes.
The same code path that runs the live bot powers the Strategy Lab backtester. What you validate is exactly what executes.
Automation handles discipline; you keep custody and override authority. Manual orders always win over bot decisions.
Rate-limit-aware polling, typed contracts shared across services, and battle-tested tooling over exotic dependencies.
Under the hood
Money software should be legible. We chose proven tools, shared typed contracts and a service per domain — nothing you cannot reason about at 3am while a position is open.
