TradingView's alert system is a powerful feature that allows users to receive notifications when specific conditions are met, helping traders capture market opportunities in a timely manner.

Alert Types:

1. Price Alerts

• Triggered when price reaches a specific level
• Can be set above or below current price
• Supports monitoring multiple price points simultaneously

2. Indicator Alerts

• Triggered based on technical indicator signals
• Examples: RSI overbought/oversold, MACD golden cross/death cross
• Supports custom indicator alerts

3. Strategy Alerts

• Signals generated by Pine Script strategies
• Can define multiple alert conditions within a strategy
• Supports different alert types for entry, exit, stop-loss, etc.

4. Drawing Tool Alerts

• Support/resistance level breakouts
• Chart pattern completions

Creating Alerts:

2. Select alert condition (price, indicator, strategy, etc.)
3. Set trigger conditions
4. Configure notification methods (email, SMS, push notification)
5. Set alert name and frequency

2. Through Pine Script

pinescript
//@version=5
study("Alert Example", overlay=true)
// Create alert conditions
alertcondition(close > ta.sma(close, 20), title="Price Breaks MA", message="Price broke above 20-day MA")
alertcondition(ta.rsi(close, 14) > 70, title="RSI Overbought", message="RSI exceeded 70")

Alert Best Practices:

1. Condition Setting

4. Testing and Validation

condition2 = volume > ta.sma(volume, 20) * 1.5
alertcondition(condition1 and condition2, title="MA Breakout + Volume", message="5-day MA crossed above 20-day MA with high volume")

2. Dynamic Messages

pinescript
alertcondition(close > ta.sma(close, 20), 
              title="Price Breakout", 
              message="Price {{ticker}} broke above MA, current price {{close}}")
