Experience with WebSockets and real-time data processing. TypeScript and HTML5 Canvas. Experience implementing order flow concepts such as Delta, Imbalance, Absorption, Icebergs, Liquidity Zones, or similar. Ability to build low-latency systems that handle thousands of market updates per second. Nice to Have Experience with Bookmap, Sierra Chart, Jigsaw, or similar platforms. Experience with CME, Nasdaq, or crypto exchange market data. Experience building trading platforms or market data visualization tools. When applying, please include: A brief description of the most relevant L1/L2 or order flow project you've built. Your specific role in that project. The technologies you used. Any examples of order flow indicators or market data visualizations you've implemented. You should be able to help define and refine the logic behind order flow signals, including how raw L1/L2 data is transformed into indicators such as absorption, iceberg detection, liquidity sweeps, exhaustion, and confidence scores. Ability to make technical decisions about indicator calculations, data aggregation, and signal quality is required.
