// 🔹 DATA
//----------------------------------------------------

// Moving averages for trend direction
sma20 = ta.sma(close, lenTrend)
sma50 = ta.sma(close, 50)

// Relative Volume
volAvg = ta.sma(volume, relVolLookback)
relVol = volume / volAvg

// Trend condition
uptrend = close > sma20 and sma20 > sma50

// 🔹 BREAKOUT + PULLBACK LOGIC
//----------------------------------------------------

// Recent breakout reference
recentHigh = ta.highest(close, 10)
isBreakout = close > recentHigh[1]

// Pullback logic
nearSupport = close > recentHigh[1] * 0.98 and close < recentHigh[1] * 1.02
lowVolPullback = relVol < minRelVol

// Reject single-bar news spike
rejectSpike = relVol > maxSpikeVol
