Setup Keltner Banda 3 e 5 - MMS

⚙️ How It Works:
• Calculates a 20-period Simple Moving Average (SMA) as the central line.
• Uses the ATR (Average True Range) to build two volatility bands:
o 3x ATR Band (more sensitive)
o 5x ATR Band (more extreme)
• Detects potential reversals when the price closes outside a band and then re-enters it.
🔍 Signals Generated:
• 🔻 Bearish Reversal: Price re-enters from above the upper band.
• 🔺 Bullish Reversal: Price re-enters from below the lower band.
• Signals are displayed with colored arrows on the chart for easy visual recognition.
🔔 Alerts:
The script also triggers automatic alerts for each type of reversal, so you can be notified in real time.
🧱 Ideal For:
• Traders using Renko, Range, or traditional candlestick charts
• Scalping or swing trading strategies
• Anyone looking for visual confirmation of price exhaustion and potential reversals
