Could you build this?
Partial Creating the web UI and custom query parser/validator is straightforward, but running low-latency screener queries against multi-asset financial market datasets requires specialized streaming and time-series data infrastructure.
What it would actually take: A production version requires a dedicated time-series database (e.g., ClickHouse or TimescaleDB) continuously ingested from expensive market data feeds (crypto, forex, indices) via WebSockets. The query engine needs an AST parser (built with ANTLR or Tree-sitter) that translates XQL constructs into optimized SQL/vectorized operations over rolling windows (RSI, moving averages). The hard part is managing real-time data subscription costs, high-throughput calculation of technical indicators across thousands of tickers simultaneously, and sub-second screener execution.
