Basic Price Action Indicator

Key Features:
Support and Resistance: Identifies support and resistance levels based on the highest and lowest values of the last 20 bars (you can adjust the lookback period with the input).
Bullish Engulfing Pattern: Recognizes when a bullish engulfing candlestick pattern occurs and marks it below the bar.
Bearish Engulfing Pattern: Recognizes when a bearish engulfing candlestick pattern occurs and marks it above the bar.
Background Coloring: Highlights the chart background with a green or red color based on the pattern detected, providing an easy visual cue.
How to Use:
Support and Resistance levels will be plotted on the chart as green and red lines.
Bullish Engulfing patterns will be marked below the bars with a “BUY” label.
Bearish Engulfing patterns will be marked above the bars with a “SELL” label.
The background color will change based on the detected price action pattern (green for bullish, red for bearish).
