// The "Double Vegas SuperTrend Enhanced" strategy uses two SuperTrend indicators with different ATR and Vegas Channel settings 
// to identify market trends and generate trades. Trades are executed only when both SuperTrends align in the same direction. 
// The strategy includes configurable take-profit and stop-loss levels, and plots the SuperTrend levels on the chart.
