Does it work? Testing supply and demand zones honestly
Decades of research on support, resistance and chart rules find effects that are real, small and fragile. This lesson reviews that evidence, shows why a bounce rate is not a profit, and builds a mechanical zone detector in Python so the method's own predictions can be tested.
What really sits at a price level: orders, clustering and stops
The supply and demand story says unfilled institutional orders wait at old prices. This lesson checks each part against how orders actually work: order splitting is real, parked leftovers mostly are not, and levels do matter, largely because stop and profit orders cluster at round numbers.
Supply and demand zones: what the method claims
Supply and demand trading marks price areas where a market left a small base and moved away hard, then trades the return to them. This lesson sets out the method as its practitioners teach it: the four zone patterns, what makes a zone strong, and how entries and stops are placed.
