// This strategy, "VIDYA ProTrend Multi-Tier Profit," is a trend-following system that utilizes fast and slow VIDYA indicators 
// to identify entry and exit points based on the direction and strength of the trend. 
// It incorporates Bollinger Bands as a volatility filter and features a multi-step take profit mechanism, 
// with adjustable ATR-based and percentage-based profit targets for both long and short positions. 
// The strategy allows for more aggressive take profit settings for short trades, making it adaptable to varying market conditions.
