Stock Screener vs Backtest Scanner
Learn the difference between stock screening, options scanning, and historical backtest scanners for repeatable research.
Frequently asked questions
Can I backtest with live scanner output?
Only if you store point-in-time snapshots. Live output alone is not enough for historical analysis.
Which tool should come first?
Use a stock screener for ticker discovery, then an options scanner for contract selection, then a backtest process for rule validation.
