How to read it

• Amber means funding was positive, so longs paid shorts. Holding a long there costs you.
• Green means funding was negative, so shorts paid longs. Holding a long there paid you.
• A row that is consistently darker than the others is a venue where the same position quietly costs more, which is exactly the cost the fee table never shows.
• Two venues with opposite colors at the same moment are a spread. The funding page ranks those pairs.
