Buying an oversold reading on its own is how you catch a falling knife: RSI can sit under 30 for weeks in a genuine downtrend. Waiting for the cross back up asks for evidence the selling has stopped, and the 200-day filter restricts it to stocks that are pulling back inside an uptrend rather than unwinding.
