+function detectMarketRegime(indicators) {
+  if (fearGreed < 25 && vix > 30 && dollarIndex > 105) {

+  if (vix > 30) multiplier += 0.3;
+  if (socialSentiment === 'extremely_negative') multiplier += 0.2;
+  
+  // Greed indicators (decrease size)  
+  if (fearGreed >= 75) multiplier -= 0.5;
+  if (vix < 15) multiplier -= 0.3;
+  if (googleTrends > 80) multiplier -= 0.4;
