// 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
