```sift
where williams_r < -80 and close > sma(200)
```

Williams %R measures where today's close sits inside the recent high-low range, so a reading under -80 means the stock is closing near the bottom of its range. It reacts faster than RSI, which makes it better for spotting the turn and worse for confirming it.
