+// ============================================================================
+// ORDER BLOCK TRADING STRATEGY - SMART MONEY CONCEPTS
+// ============================================================================
+// This strategy identifies institutional order blocks and trades reversals
+// when price returns to these zones. Based on ICT (Inner Circle Trader) concepts.
+//
+// Simplified approach:
+// - Bullish Order Block: Strong bearish candle followed by reversal upward
+// - Bearish Order Block: Strong bullish candle followed by reversal downward
+// - Entry: When price retests the order block zone with confirmation
+// ============================================================================
+
