Cross-Exchange Arbitrage Monitor
A real-time order-book monitor designed to compare executable spreads after trading fees and rebalancing cost.
Problem
Displayed exchange spreads can be fake opportunities once fees, order-book depth, transfer constraints, and rebalancing costs are included.
Description
What I built or investigated
A real-time monitoring architecture intended to compare executable cross-exchange opportunities rather than headline prices.
Iterations
The work did not happen in one jump.
- 01
Required live order-book analysis instead of ticker-price comparison.
- 02
Included trading fees and the cost of keeping balances distributed across exchanges.
- 03
Designed around stale-data prevention and continuous refresh.
- 04
Separated monitoring and decision support from automatic execution until risk controls are defined.
Result
Where the project landed
A scoped software architecture and UI concept, not a claim of profitable unattended trading.
Lessons
What carried forward
- The spread is not the profit.
- Liquidity and inventory placement are core parts of an arbitrage system.
- Automation should come after observability and controls.
