Show HN: Open-source market screener and backtester for algo traders

I built an open source toolkit to scans markets for setups and runs fast backtests so you can validate ideas before committing to it. It's entirely built with algo traders in mind and gives you options to connect screening with multi symbol multi strategy backtests.

Repo with code and docs: https://github.com/GuntharDeNiro/gunbot-quant

Optional integration with Gunbot lets you pipe signals or push a validated strategy to live trading. It also runs fully standalone.

I’m looking for critical feedback on the workflow, default metrics, and what outputs would help you iterate faster.
