Smart Money Scanner Suite v6 - Optimized

WHAT IT DOES (longer version in the script):
// Identifies "Smart Money Stepping Back" (SMSB) zones where institutions quietly
// build positions without moving the market. Signals appear when ALL 4 conditions align:
//
// 1. OBV DIVERGENCE → Price up/OBV down (distribution) or Price down/OBV up (accumulation)
// 2. LOW VOLUME → Below 1.5x average (stealth activity)
// 3. NEAR VWAP → Within 0.5% (institutional fair value)
// 4. HTF CONFIRMATION → Higher timeframe shows directional momentum
