TickDB API development tutorials, WebSocket integration and SDK examples
When a quantitative team grows from three to eight researchers, something breaks silently. Strategies stop having clear owners. Backtest results live in scattered spreadsheets. One developer's "alpha
--- The Moment Every Quant Team Reaches Three years into running a systematic equity strategy, the team's Python scripts that once processed gigabytes of daily tick data without complaint start timing
--- The Problem That Haunts Every Quant Developer Imagine you are building a cross-asset trading system. You need real-time data from US equity markets, Hong Kong stocks, and cryptocurrency exchanges
--- Three people. Tight budgets. Ambitious alpha targets. The 3-person quantitative trading team occupies a strange middle ground: too small for enterprise infrastructure, too ambitious for spreadshee
The most expensive mistake a quant researcher makes is not a bad signal — it is trusting a backtest built on the wrong architecture. Vectorized backtests are fast. They are also dangerously deceptive
--- In 2021, a proprietary trading firm in Singapore spent three months building a custom adapter layer just to normalize TickDB's raw order book data into the format their internal risk engine expect

Most aspiring quantitative traders never run a single backtest because they believe the barriers are too high. They assume professional-grade systems require professional-grade budgets — proprietary d
--- In a production trading system, the mismatch between data arrival speed and processing capacity is not an edge case — it is the default operating condition. A 10Gbps market feed can generate thous
The decision between REST and WebSocket is not a philosophical debate — it is a matter of engineering trade-offs that directly affect latency, server load, and the complexity of your client code. Choo
--- The 3 AM Realization At 3:14 AM on a Tuesday, you find it. The paper that promises everything: a novel alpha factor with a Sharpe ratio of 2.3, published in a peer-reviewed journal, backed by five
