DeployQuantOversold
A condition where a price has fallen hard and fast enough that an oscillator like RSI reaches a low extreme — conventionally RSI below 30. Oversold does not mean cheap or safe: in a genuine downtrend an asset can stay oversold for weeks. Mean-reversion systems treat oversold readings as candidate entries, usually in assets with strong long-term upward drift.
