Support

Support is a description of past behaviour, not a floor — it is a level where buyers appeared before, and there is no mechanism guaranteeing they will appear again. It is better thought of as a zone than a line, since exact prices rarely repeat and defining it too precisely creates false confidence. Part of its apparent effectiveness is self-fulfilling: enough participants watch the same round numbers and prior lows that orders cluster there, which is a fact about behaviour rather than about value. Nothing here suggests a price will hold at any level, and support levels break routinely.
