Multi-MA Crossover Alert by Funded Relay

136
Multi-MA Crossover Alert is a simple yet powerful trend-following indicator that combines three moving averages to help identify trend direction and potential reversal points.

What it shows:
• Fast SMA (default 20 periods) – reacts quickly to price changes
• Medium EMA (default 50 periods) – smoother medium-term trend
• Slow SMA (default 200 periods) – long-term trend reference (often called the "death/golden cross" level)

Features:
• Dynamic coloring: Lines turn green when above the slow SMA (bullish bias) or red when below (bearish bias). The slow SMA stays gray for clear reference.
• Background tint: Light green/red background highlights the overall trend based on Fast SMA vs Slow SMA.
• Crossover alerts: Triggers notifications when the Medium EMA crosses above/below the Slow SMA (classic trend change signal).

How to interpret the signals:
• Bullish trend: Fast and Medium lines are green and above the Slow SMA → price is in an uptrend. Look for buying opportunities on pullbacks.
• Bearish trend: Fast and Medium lines are red and below the Slow SMA → price is in a downtrend. Look for selling/short opportunities on rallies.
• Bullish crossover (alert): Medium EMA crosses ABOVE Slow SMA → potential start of stronger uptrend or reversal from downtrend.
• Bearish crossover (alert): Medium EMA crosses BELOW Slow SMA → potential start of stronger downtrend or reversal from uptrend.

How to use it correctly:
1. Add the indicator to your chart via "Indicators" → Community Scripts.
2. Adjust the input lengths to match your timeframe and style:
- Shorter periods (e.g. 10/30/100) → better for intraday / scalping
- Longer periods (e.g. 50/100/200) → better for swing / position trading
3. Enable "Enable Crossover Alerts" if you want TradingView notifications (set alerts via the alert menu: condition = "alert() function calls only").
4. Use in combination with:
- Support/resistance levels
- Volume confirmation
- Other indicators (RSI for overbought/oversold, candlestick patterns)
5. Best on higher timeframes (1H, 4H, Daily) to reduce noise. On very low timeframes, false signals increase — always confirm with price action.

Important notes:
• This is NOT a standalone "buy/sell" system — no indicator is 100% accurate. Always use risk management (stop-loss, position sizing).
• Backtest on your assets/timeframes before live trading.
• Works on all markets: stocks, forex, crypto, futures, etc.
