TradingView Pine Script (v6) that combines:

• Heikin Ashi candles for smoother trends.

• EMA (7, 21, 50) for short, mid, and long-term trend filters.

• SMA (user adjustable, e.g., 200-period).

• RSI for momentum confirmation.

• Auto Buy/Sell signals when trend + momentum conditions align.

How this works:

• Buy Signal: When EMA 7 crosses above EMA 21, trend is bullish (above EMA 50 & SMA), and RSI > 50.

• Sell Signal: When EMA 7 crosses below EMA 21, trend is bearish (below EMA 50 & SMA), and RSI < 50.

• Plots: EMA 7 (teal), EMA 21 (blue), EMA 50 (red), SMA (orange).

• Alerts: Auto alerts for BUY and SELL signals.

• RSI Panel: Separate RSI indicator with OB/OS lines.
