+# SILOQY System Motto
+
+## English
+**"Through music, not war"**
+
+## Latin  
+**"Per musicam, non bellum"**
+
+---
+
+*The philosophy of SILOQY: Finding harmony and patterns in market movements rather than forcing trades through aggressive tactics. Music represents the mathematical patterns, natural order, and underlying harmonies that govern systems - while war represents brute force and unnatural manipulation.*
+
+*JERICHO waits for the market's own "walls" to fall, then signals the breakthrough moment.*
