The footprint: how to read it

The footprint chart is the heart of order flow. Instead of a coloured body, each candle displays a column of prices, and beside each price two numbers: what was executed as aggressive selling at the bid, and what was executed as aggressive buying at the offer. This way you see inside the candle, not merely its outer shape.

How to read the cell

Each cell is read like this: [aggressive sell] × [aggressive buy] at that price. When buying dominates, the cell is coloured green; when selling dominates, it is coloured red. The difference of each row is computed to tell you which side controlled at that specific level.
