Multi-EMA Indicator with ADX

DESCRIPTION:
// This indicator provides a comprehensive EMA-based trading system that identifies high-probability
// trend continuation and reversal opportunities. The strategy uses the relationship between
// 5 different EMA periods (5, 10, 20, 35, and 50) to determine market structure.
//
// FEATURES:
// - Visual indication of trend direction with color-changing fills between EMA pairs
// - Automatic detection of ideal entry conditions in both bullish and bearish markets
// - ADX filter to confirm trend strength and reduce false signals
// - Color-coded price candles for clear visual signals
//
// SIGNAL LOGIC:
// BUY SIGNAL when:
// - EMA(5) > EMA(10) [short-term bullish]
// - EMA(20) < EMA(10) but EMA(20) > EMA(35) [medium-term momentum]
// - EMA(35) > EMA(50) [long-term bullish]
// - Price closes above all EMAs [immediate strength]
//
// SELL SIGNAL when:
// - EMA(5) < EMA(10) [short-term bearish]
// - EMA(10) < EMA(20) [medium-term weakness]
// - EMA(20) < EMA(35) [medium-term weakness continuing]
// - EMA(35) < EMA(50) [long-term bearish]
// - Price closes below all EMAs [immediate weakness]
//
