Romazes expanded instrument coverage in the QuantConnect/Lean repository by adding support for the Australian Dollar (6A) futures option and introducing expiry rules for several new CME futures currencies, including 6B, 6M, 6J, 6E, and 6C. Using C# and leveraging expertise in API development and financial derivatives, Romazes refactored expiry logic to improve mapping accuracy and expiration calculations. Comprehensive tests were added to validate the new instruments’ behavior, enhancing backtest reliability and reducing mispricing risk. This work deepened the platform’s readiness for quant trading and broadened client coverage, reflecting a focused approach to robust financial data engineering.
