The fillable edge,
not the headline.
APE is a dedicated application for cross-exchange spot arbitrage — separate from TIP, with its own install, its own workspaces, and a different job entirely. It discovers, validates, ranks and executes opportunities across integrated venues — with pre-funded inventory, coordinated multi-leg execution, and policy-bound automation. For desks that trade what actually fills.
What you see above is the real computation APE runs every few hundred milliseconds across every configured pair. Fill the target notional at the VWAP of each side's book, subtract fees, slippage, and a safety buffer, publish net edge in bps. Only opportunities that clear min_edge_bps reach the execution queue.
Three
non-negotiable principles.
Lifted verbatim from the APE master spec — the rules that separate an operational arbitrage engine from a spread-watcher.
Execution realism beats theoretical spread
Net executable value only. VWAP against the target notional, fees both legs, slippage model, safety buffer. If it won't fill, it isn't ranked.
Pre-funded balances beat post-signal transfer chasing
Both legs must sit on both venues before APE looks at the opportunity. No bridge risk, no transfer windows, no race to fund.
Manual-first before automation
Paper for weeks. Manual for months. Auto only after live evidence on a whitelisted workspace. Automation is earned.
Three gears,
each earned.
Paper
Same signals, same risk engine, same slippage model. Zero real fills. Stays on for as long as your book wants reassurance.
Manual
Operator approves each execution plan. APE computes the ranked opportunity; a human clicks Execute. For low-cap go-live.
Auto
Policy-bound, feature-flagged off by default. Enabled only on whitelisted workspaces after live-trading validation.
Professional desks,
four roles, one workspace.
Owner / Operator
Sets workspaces, capital rules, exchange accounts.
Trader / Analyst
Reviews opportunities, executes manually, monitors P&L and venue performance.
Risk Supervisor
Defines policies, per-venue caps, emergency stops, auto-trade permissions.
Developer / Maintainer
Integrations, deployments, metrics, recovery.
Five gates.
Each unlocked by live evidence.
