Follow a curated reading path through the systems, markets, and questions behind HFT API engineering.
API Architecture
Understand the system before optimizing a component. These guides connect the meaning of trading messages to market-data health, order ownership, session recovery, and reproducible performance tests.
4 GUIDESMarket Engineering
A shared API vocabulary does not make every market identical. Explore the contract definitions, quote conventions, and execution evidence that change when moving between stocks, futures, forex, and derivatives.
