is3pm = (hour == 15 and minute == 0)  // Check if it's 3 PM

// --- 2. Daily Candle Analysis (Bullish Patterns) ---
// Bullish Engulfing pattern
bullishEngulfing = close > open and open[1] > close[1] and close > open[1] and open < close[1]

// Morning Star pattern

// Three White Soldiers pattern

// --- 4. Avoid Over-Extended Stocks (5-10% intraday gains) ---

// --- 6. Exit Strategy - Pre-Market & Opening Observation ---
// This part requires real-time data and pre-market data, which isn't supported directly in Pine Script
// But, we can simulate exit strategy by showing potential exit points based on the gap-up opening:
gapUpOpening = open > close[1] * 1.02  // If the stock opens 2% above the previous close
hold15Min = gapUpOpening and close > low[1]  // Hold if price doesn't break the previous low
