// ====== INPUTS =======
// =====================

// Trend Settings
fastLength     = input.int(21,  "Fast EMA Length")
slowLength     = input.int(55,  "Slow EMA Length")
trendLength    = input.int(200, "Trend Filter EMA Length")

// Momentum Filter
rsiLength      = input.int(14,  "RSI Length")
rsiBullLevel   = input.int(55,  "RSI Bullish Threshold")
rsiBearLevel   = input.int(45,  "RSI Bearish Threshold")

// Volatility Filter
atrLength      = input.int(14,  "ATR Length")
atrMultiplier  = input.float(1.0, "ATR Volatility Multiplier")

// =====================
// ===== CALCULATIONS ==
// =====================

// EMAs
fastEMA  = ta.ema(close, fastLength)
slowEMA  = ta.ema(close, slowLength)
trendEMA = ta.ema(close, trendLength)

// RSI
rsiValue = ta.rsi(close, rsiLength)

// ATR
atrValue = ta.atr(atrLength)

// Volatility condition
volatilityCondition = ta.tr(true) > atrValue * atrMultiplier

// =====================
// ==== TREND LOGIC ====
// =====================

// Bullish condition
bullishCross = ta.crossover(fastEMA, slowEMA)
bullishTrend = close > trendEMA and rsiValue > rsiBullLevel and volatilityCondition

bullishSignal = bullishCross and bullishTrend

// Bearish condition
bearishCross = ta.crossunder(fastEMA, slowEMA)
bearishTrend = close < trendEMA and rsiValue < rsiBearLevel and volatilityCondition

bearishSignal = bearishCross and bearishTrend
