- For each detected pattern:
  - Plot a green upward arrow below the candle for bullish patterns with the text “BUY: Pattern Name”

  - Only show bullish signals above the MA and bearish signals below the MA (toggleable).
- Include an optional RSI panel:
  - RSI length input
  - Overbought and oversold levels
  - Allow RSI to be used as an additional filter for signals (on/off)
- Ensure the indicator overlays signals on the price chart and uses clear labels and arrows 
- Allow user inputs to enable/disable each candlestick pattern individually
